QElectroTech is an application to create primarily, electrical, electronics, automation and control circuits. However, QElectroTech can be exploited to create mechanical objects to illustrate processes, instrumentation drawings among various creative possibilities. QElectroTech is a good professional quality drafting application for various drawings that form a project.
QElectroTech has a large collection of standard and custom symbols, referred to as elements, that describe most of the commonly used components in electrical, hydraulic, pneumatic, computer systems. These elements can be selected drag dropped with mouse on to a diagram editor and connected with lines to represent or describe a system. A large number of such diagrams can be drafted under a project. QElectroTech is easy to use professional software that is free to download, install, use and develop.
QElectroTech also consists of an inbuilt element editor that permits creation of newer elements that do not exist in the collection. Elements in the QET collection are not editable i.e read only. But, once the element is drag dropped into a diagram, it is automatically added to “imported” collection in a duplicate copy. This copy of the element will be available for editing to effect suitable changes to create customized symbols.
The finished diagrams can be exported to various formats like dxf, pdf, jpg, png etc.,. QElectroTech is available in many international languages. It is also possible to use multiple languages in the same drawing / project.
The elements in QElectoTech are saved in a xml format. The projects and diagrams can be saved as *.qet format for further editing.
QElectroTech is distributed as a Free Software released under the GNU / GPL license. As on the date, a stable version 0.4 is released for systems operating on MS Windows, GNU / Linux and MacOS.

Tool bar houses buttons (icons) for performing basic operations in the QElectroTech window. The tool bar icons are segregated in groups with a separator. Individuals segments that form the “Tool bar” are shown and discussed here. The tool bars can be moved by left clicking and holding to select these separators and drag dropping to a new location.
Fig.2 QElectroTech Toolbar:
The Fig.2 shows the first segment of the tool bar containing some active buttons and some inactive buttons. The options provided here apply to the entire but, to the selected project only. Clicking New will create a new project in the same window, similarly other active options are Save or Saveas changes, Close the project, Print the project etc.,. The inactive buttons shown here work on individual element or selected elements that is / are added to the drawing. These options are activated when elements are selected. Individual element can be selected with a single left mouse click. Multiple elements can be selected by holding the control key from keyboard and selecting each element with a left mouse click. The tool bar buttons perform the action on all the selected elements simultaneously. The buttons provided here are Undo, Redo, Cut, Copy, Paste, Delete, Rotate and Properties.
Fig.3 QElectroTech Toolbar:
The Fig.3 shows the next segment of the tool bar containing active buttons. The options provided here are Addatextfield, Addapicture, Addamechanicalconnection (straight line tool), Addarectangulararea, Addanellipsearea and Addapolylinearea. The options from Addamechanicalconnection are primarily special drawing aids in the main window. These are selected by single left mouse click and deselected by pressing the Esc key from the keyboard. The operation of these geometry buttons are enumerated here:
Straight line, rectangle, ellipse tools:
Single left click the button in the tool bar to select. Left click two points on the drawing area between which the shape is to be created.

Single left click the button in the tool bar to select. Left click the required number of points on the drawing area connecting which the shape is to be created. Double click at the final point to complete the geometry.
Hover over the completed shape with the cursor, when a gray shadow is developed around the shape, double click to open special formatting options for the shape like, choosing line styles, locking the position and scaling the shape.
Fig.4 QElectroTech Toolbar:
The Fig.4 shows the next segment of the tool bar containing three active buttons. The options provided here are Diagramproperties, Resetconductors, and Automaticconductorcreation.
Reset conductors: Conductors can be adjusted / altered by :
Fig.5 Reset conductor tool: (The following steps are animated in here.)
Moving one of the element that is connected by the conductor.
Single left click the conductor with left mouse button.
Observe the conductor changes to thick red line with green squares at least one on each horizontal or vertical sections of the conductor.
Select the little green square with left mouse click and drag drop to alter the conductors.
If you decide to revert back the conductor modification to initial drawing, just click the resetconductor option in the tool bar.
Automatic conductor creation: This is a new feature included in QElectroTech version 0.4. By default the tool is “active” upon starting the application. It permits automatic conductors creation when two terminals of an element are aligned in either vertical or horizontal plane.
Fig.6 Auto conductor creation:
To use this setting, reposition the element relative to another element between which conductors are to be drawn.
Observe the vertical or horizontal guides that appear during repositioning.
For vertical conductors (North/South), the vertical guide line, which is thick blue in color turns green on alignment.
Drop the element being moved at this point to automatically create conductors between them.
You may now adjust your elements (reposition) to suit your requirement. The conductors will take shape automatically as you reposition your elements.
The elements panel tools are shown highlighted with green box in the Fig.1. The panel contains essential tools for creating or editing or deleting elements and categories that can be used in the `Work Area’. These tools perform operations on elements, templates or categories. The entire column of utilities effect templates and elements and are discussed below:
A filter is provided to quickly search elements by looking for matching input keywords typed into the search bar. When a keyword is entered, each matching element is displayed along with its tree, i.e. under the category in which the element is located. Only the categories which hold a matching element for the searched keyword are displayed (refer Fig.1). The entered keyword can be cleared by left clicking the X button (provided left to the search keyword text input field) to display normal categories and QET elements. The keyword can also be cleared by using backspace key or delete key from keyboard or selecting the text with mouse and deleting the entered keyword(s).
Elements panel tool bar
The “Elements panel tool bar” contains tools to create, edit, delete and reload categories and elements. The function of each of the tool is explained in animation Fig.36 under Section.10.
QET Drawing templates (QET title blocks)
The “title block” has a number of templates to select for the drawing. User can also design his custom template for the project. A set of Standard templates are provided with the QElectroTech installation. A template can be applied to the drawing by selecting the template and drag dropping it on to the “drawing or the work space”. The templates can be edited from “diagram properties” using the drop down box provided right to the template field. The QET standard templates are read only and cannot be edited in place. However, once a template is applied to a drawing, its copy is imported under the project title shown with a blue highlighted box in Fig.1. You can right click the imported template and choose to edit the template. Refer to a sample tutorial —– under section — .
QElectroTech provides a set of readily available elements in “QET Collection” under a relevant category. Elements can be selected with mouse and drag dropped onto the work space to add them to a drawing. It is possible to search for an element using keywords in the filter discussed earlier under the topic filter.
User title block
A user can edit the standard templates as mentioned earlier and use it for a project. These edited templates are only available under the project or to the projects opened simultaneously in the same window. However a user can also create a custom template and preserve it for future uses by adding it to the user title block. The title block is a place where user(s) can design their own templates and preserve them for future use. New categories (folders) can be created under the title block to hold custom templates.
User collection is the place where user(s) can add new categories and elements or to delete or modify earlier added categories and elements. The user can create a new element using basic shapes or tools in the element editor or modify imported elements and save. The user also has an option to import new elements stored in a file. Refer to a short animation graphic in Fig.36 under Section.10.
Two tabs are provided to the bottom left corner of the QElectroTech application main window, to switch between the elements panel and the Undo panel. Elements panel is default view in QElectroTech. Undo tab records each change to a diagram in the chronological order. The user, can at any point of time may wish to go back to any previous point in the diagram by selecting it in the undo tab. Each change that is effected by user’s action in the diagram are recorded vertically in the Undo window. Select a point in the history where he/she wishes to return to and switch back the tab to “elements panel”. The changes that were effected after the event will be undone. After the undone action, the user will find that the actions that were undone are highlighted in light pink color, under appropriate category in the elements panel. These actions are marked internally by QElectroTech as unused in the project. The tabs can be turned off or on from the tool bar settings and selecting the display. Unchecking the options will turn off the corresponding views tab or tools in the main window.
However, it should be understood that only actions that are related to drawing can be undone such as adding or deleting of elements, conductors etc.,.
The help bar is the space below the control tabs, the bottom left most corner of the main window. It is very useful for beginners of QElectroTech in the way that it gives information about the field that is pointed by the cursor. A user can learn about a field by simply pointing it with the mouse and looking at the help bar.
The drawing or diagram can be given a name in the diagramproperties. Either click the diagramproperties from the tool bar or double click the drawingtab. There are many other options that can be set in the diagram properties window. Once a name is given to the drawing, it gets displayed in the drawingtab.
The project is named by “Project XXXX” where XXXX is the name of the file (*.qet) as which it is saved. In QElectroTech each project is a different file. Individual drawings forming part of the project are displayed when a project is selected. It is possible to work with many projects in the same window.
By default, QElectroTech displays the project name as “untitled project” in the project title tab and “Untitled” in the diagram title tab. The user can save the project by giving it a name of his/her choice as a file. The project title tab displays the name of the project, which is saved as “*.qet” file on the computer. There is an option to close the project, by clicking at the top right corner of the project title bar. A new project can be opened in the same window, which opens as a new tab in the project title. User can switch from one project to the other by left clicking the tabs with the mouse or pressing control+tab key from keyboard. The project title can be changed from the main menu bar Project, then selecting the ProjectProperties and entering a name for the project in the project title field.
The workspace is analogous to the drawing chart. The work space is directly affected by the template applied. By default, work space is divided into cells rows from `A’ to `H’ and columns `1’ to `17’. The rows and columns can be modified by adding or deleting rows and columns from the diagram properties window. The default size of each column is 60 pixels and that of each row is 80 pixels, both of them can be adjusted in the diagram properties. Workspace is the area where the diagram is prepared, by including elements, conductors, text and pictures. The title block section of the workspace contains information related to the drawing such as - `Author’, `date’, `Title’, `File’ and reference `Folio’ numbers.
A “name” for the project created can be given in the ProjectTitle field of Projectproperties. Click Projects from main menu to access these options. The project title tab now displays the project name as Project"name"[modified]. The project should now be saved as a file file_name.qet, the project title tab then displays project"name". A project can have this “name” different from the name of the file as which it is saved. Alternatively, a project which acquires its name from the file name can be overwritten by this action. The Projectproperties window has several options to be set. Such options are applied to all subsequent drawings added to the project. The present drawing properties should be set from the Diagramproperties option in the tool bar or by double left clicking the drawing tab. Project properties window is further explained under `Project properties`_.
By default, QElectroTech opens an Untitled diagram under an Untitled project when a new project is created (refer Section.2). A new diagram can also be created by pressing Control+t keys from keyboard or by clicking the addadiagram button located rightmost on the diagramtitlebar or by selecting the addadiagram from the Project option on the main menu bar. The drawing name and other properties can be set by invoking Diagramproperties button from the tool bar. The Diagramproperties can also be launched from the menu bar Edit and selecting the Diagramproperties or by pressing Control+L keys from the key board. The diagram properties window has options to assign a name to the diagram, author’s name, date, changing the dimensions of the work area by adjusting number and dimensions of rows and columns, or selecting a standard template for the drawing etc.,. There is a custom tab provided for user defined keys.
QElectroTech permits customizations through configure option. To open the “configure window” click Settings from the main menu bar and select ConfigureQElectroTech. The customizations can be effected to
Configuring General window
Fig.9 Configuring General window
General window has the following customizations permitted in QElectroTech:
Appearance: (Default value is Systemcolors)
Checking the option for `Use system colors’ will make QElectroTech to pick up the same color profiles that are applied to the Operating System environment, like MS Windows or Debian Linux etc.,.
Uncheking the option will make QElectroTech appear with a default appearance, which will be immune to the Operating System Environment color profiles.
Projects: (Describes how projects appear in the main window, default value is Tabs.) These options require restarting the QElectroTech application to effect the changes.
Tabs: Checking the option will make projects appear as tabs in the QElectroTech window. Projects that are added subsequently will appear as tabs in the ProjectTitlebar.
Windows: Checking the option will make projects appear as individual windows with its own set of diagrams. Newer projects added subsequently will also behave as new windows. The Minimize, Restore and Close options for the windows appear to the right most on the “main menu bar”.
Use gestures touchpad: Use the option for touchpad control of projects tabs in QElectroTech.
Elements Management: (Default value is both options selected).
Integrate automatically the elements in to the projects: The option is reponsible to automatically import the elements added to the drawing into the Importedelements under Embeddedcollection of the project in the elements panel. In QElectroTech, the elements that are provided with the installations (in QET Collection) are not editable. However, once they are imported to the Importedelements of the project, they are available for editing in the element’s editor. They can be modified and reused in the drawing. The choice is therefore recommended. Refer to the section on `Elements editor`_ to learn to use the elements editor. You may gain quick overview by watching the animation in Fig.20 under `Section 10`_.
Highlight freshly integrated elements in the panel: The choice will generate highlighting colors over the elements imported in the Importedelements.
Yellow color flashes over the parent element and the element imported to the Importedelements at the time of importing.
If the elements that are imported to the project under Importedelements are subsequently deleted from the drawing(s), then these elements will be permanently highlighted in light pink color indicating that they are unutilized in the project. The highlight is however only displayed under the project in the elements panel and will disappear if they included again in any of the drawings under the project.
Language: (Default value is System ) QElectroTech comes with many languages and the default language can be selected here. The language option can be set from the combo box next to language settings. You can either choose a fixed language in the QElectroTech application by opting your choice or leave it to the System option. In which case, QElectroTech automatically starts with the Operating System Environment language preference. Changing the system language would automatically change (update) the language for QElectroTech application.
Fig.10 Configuring New Project - Diagram
(2.1) Diagram (Folio): Some of the workspace settings are provided here. The customizable options include:
Diagram size (Dimensions of folio):
Number of columns and rows for the grid.
Size of each column and row.
The headers for the columns and rows can be turned on / off. Headers are the `A’, `B’, `C’ etc., for rows and `1’,`2’,`3’ etc., for columns.
Option to fill gray color in the back ground.
Information title block: The template drop down box contains six options (drawing templates) to be set as default for new drawings or projects. The specific terms (fields) that are used here will be explained together with their use. The fields provided will be applied by default to all subsequent projects / diagrams as the case may be. The information title block comes with two tabs Main and Custom. The Custom tab is discussed under template editor in Section.11 .
Title provides the default name of the diagram that will open with each of the subsequent projects. Title name is usually given to describe the drawing for example, like a power generation system, distribution system etc.,
Author provides field to enter the name (or a pseudo name) of the person creating the diagrams in the project.
Date field has options to :
Not specify a date for the drawings
Apply today’s date i.e. the computer systems date will be applied to all subsequent diagrams. The value is dynamic changes with each passing day.
To set a default date (fixed) to every subsequent drawing. The value is fixed and do not change.
File name applies to the top right field (cell) in the drawing / diagram title block. The file name can be for example the name of the system in a project. A system can have its drawing spread over several drawing sheets and all carry the same system name i.e. file name.
Folio name is an additional field to specify the drawing in a file. Folio names are usually provided to specify the current diagram in a sequence of files across which a file is named (system is specified). The field is by default set as %id/%total, which is a dynamic nomenclature. When a new diagram is added in the same project it is updated as “the number of the current drawing” / “total number of drawings created”.
Fig.11 Configuring New Project - Conductor
(2.2) Conductor: Conductor is basically the line that connects two elements in the drawing. The customization window has options to tweak conductor type and conductor appearance.
Conductor type: The options that are provided to customize the conductor type and its text appearance as:
Multiline: The optional default text that should appear with each conductor can be entered in the Text field. The size of the font can be specified in the adjacent Size field. On the otherhand, the text field can be made invisible by “Unchecking” the Visible option i.e. no text will be displayed across the conductors, when they are created. Note: The Showonetextperfoliopotential option is still under development.
Angle of conductor labels: The option to set an angle to the text that appears together with each conductor created can be set here. The options are provided under two categories, namely -
Vertical: The vertical option is to set the default angle to the text that appears in the vertical direction. The angle can be set in eight specified intervals with the graphic interaction tool. Click the green squares on the yellow circle to set the specified angle. Also, a finer control over the angle precision can be achieved upto two decimal places in the adjacent combo box in degrees, by keying the value from the key board. Clicking the up or down keys in the combo box increments or decrements the angle by one degree only.
Horizontal: The horizontal option is to set the default angle to the text that appears in the horizontal direction. The angle can be set in eight specified intervals with the graphic interaction tool. Click the green squares on the yellow circle to set the specified angle. Also, a finer control over the angle precision can be achieved upto two decimal places in the adjacent combo box in degrees, by keying the value from the key board. Clicking the up or down keys in the combo box increments or decrements the angle by one degree only.
Single line: The single line formatting provision is strictly included for the electrical diagrams. The provision shortens the representation of conductor(s) between two or more elements by including added information over the conductors, to convey a more meaning. In a typical domestic AC circuits we use a phase, a ground and a neutral wire. A drawing for such a circuit will require adding three conductors running parallel between the elements. This may clutter drawing and an alternate way exists to specify that a single line shown in the drawings represents a phase, a neutral and a ground cable. This is possible by choosing the Singleline radio button and checking out the options (default) ground, neutral and phase. The neutral option has additional option called PEN to specify that the neutral cable is a specific Protected Earth Neutral. It is therefore logical to have a requirement for PEN to be active, that both ground and neutral be checked out first. The following points will summarize operations under Single line.
A conductor can be formatted as any one or a combination of ground, neutral and phase. The small conductor snippet is provided to generate a preview of the likely conductor appearance after effecting the options.
Selecting both options ground and neutral will permit to specify whether the conductor is a PEN type or not.
The phase option is additionally facilitated with a slider and a double spin box, to specify the number supply phases. Provision exists to set a maximum of three phases only.
The number of phases can be specified either by selecting and dragging the slider bar or keying in direct value in the double spin box or also by clicking the up / down keys of the double spin box to increment or decrement value by 1 unit.
Conductor appearance: Options that are provided to customize conductor appearance are:
Color: A default color can be specified for the conductor from the color selection box. Left click on the color setting box, and pick up a color either from the existing basic colors or define a custom color by using the color mixer options and select it in the pop up color window. Click Ok to apply the option or Cancel to exit without applying the changes.
Style: Currently three styles are available to choose from, for the default conductor appearance. The option can be selected from the list box next to the Style: option.
The text that appears for the conductors created can switch between horizontal or vertical by adjusting the conductors. Refer to Section.8 to learn how to adjust conductors.
On the low voltage circuits, sometimes the earthing and neutral functions are combined in the same conductor of the supply cable; this is known as a PEN conductor. The PEN conductor is earthed at multiple locations along its length using separate conductors (earthing). The conductor will be branched at each consumer (in domestic supply it may be a house) as a “neutral” and “earth”. This kind of distribution of electrical power supply is called TN-C system. This PEN conductor will provide a return path for both operating conditions - a neutral current flow under normal operating conditions and for the earth fault current during the duration of a line to earth fault.
Fig.12 Configuring New Project - Reports folio
(2.3) Reports Folio: A set of parent and child elements are provided in QET Collection along with two other special referencing elements in QElectroTech. The two special referencing elements are Previousfolio and Nextfolio located in the tree QETCollection –> Electric –> All-pole –> Sheetreferencing. Refer to section uuuuuuu for more description on reports folio. The referencing index that these elements generate between different drawings with in a project or within the same drawing can be customized from Label of report folio in the Reports Folio tab. There are three keys f (the number of folio), l (line number), c (the column number), which are internally defined in QElectroTech. User can shuffle these keys to customize his/her default reference indexing. % symbol should be used prefixed to these keys to replace the keys with corresponding numbers in the drawing. A short explanation to the set of parent and child elements is provided in Cross References.
Fig.13 Folio elements in QET Collection
Fig.14 Configuring New Project - Cross references
(2.4) Cross References: The cross references tab is provided to improve electrical diagrams, particularly when using relays. Often electrical diagrams for example, like motor starters and protection systems will have a number of contacts and coils (Relays), with the coil often located at a different place (or sheet). Correct referencing of the contacts for their actuating coils in the diagram is of prime importance to interpret the functioning or operation of the system. A set of referencing relay elements are provided under QETCollection –> Electric –> All-pole –> Relays,contactorsandcontacts. The referencing customizations can be effected from this Crossreferences tab for subsequent projects or drawings. A brief explanation about the customization options are enumerated here:
Positioning: Two options are available to place the references of the contacts linked to a coil, either below the coil’s label or in the footer region (bottom of the drawing & inline below the parent coil).
View cross: The referenced contacts (actuated by the coil) are displayed as a table of two columns, one for Normally Closed (NC) contacts and the other column for Normally Opened (NO) contacts. The sequence of the entries in these columns is decided by vertical distribution of the linked contacts i.e. a contact located above the coil in the drawing is displayed first than a contact located below the coil.
View contacts: The referenced contacts (actuated by the coil) are displayed as a contact, unlike the earlier option of a two column display in Viewcross. The sequencing of the entries falls in the same order as described for Viewcross.
Option display cross: The fields customize a prefix to the texts that appear under Viewcross. The options provided here are:
Show the power contacts in the cross: Checking the option will permit the power contacts to be displayed when the references are customized as a cross under a coil.
Prefix of power contacts: The text field lets the user to define a customized prefix to the power contacts.
Prefix of delayed contacts: The text field lets the user to define a customized prefix to the delay contacts.
Prefix of change over contacts: The text fied lets the user to define a customized prefix to the change over contacts.
Fig.15(a) Illustration of Referencing fields using an example(Combustion system); Note the positioning option is set to ``view contacts`` (not cross)
Fig.16 Configuring New Project - Export
The drawings from QElectroTech can be exported to different formats. Currently it is possible to export the drawings from QElectroTech as svg (Scalable Vector Graphics), bmp (Bit map), dxf (Drawing eXchange Format), jpg (Joint Photographers’ Expert Group format) and png (Portable Network Graphics). The various configuring options provided in the export window are:

You can only choose one of these two options (a) or (b).
The default settings are Exporttheborder, Drawtheborder, Drawtheinset and Keepconductorscolors only. Other options are left for the user to choose.
Fig.17 Configuring New Project - Printing
The printing options are similar to the export options. Refer to the description for Export. The default values are Drawtheborder, Drawtheinset and Keepconductorscolors only. Other options are left for the user to choose.
QElectroTech has a number of elements listed as a tree under QETCollection in the left pane of main window. The collection of elements (shown highlighted in yellow square in Fig.1) is organized under relevant categories (folders). Users can click on the + symbol located left to the category to surf the elements or more categories under its tree. Alternatively an element can be searched quickly using Filter field, refer to filter. Each element can be selected using left mouse click and drag dropped on to the work area to include it in a diagram. The elements can be positioned any where in the work area. Some of the tools in the tool bar apply to elements such as cut, copy, paste, delete, rotate, element properties and select tools. Refer to from tool bar.
Some of the operations possible with elements:
Cut and Paste
Elements can be cut paste by using the `scissors’ icon and `Paste’ icon from the the tool bar.
Standard keyboard shortcuts like Control+x will also cut the element and Control+v will paste the element.
Restrict the cut and paste functions within the same project. The elements would suffer data loss if the operations are effected over more than one project.
Elements can be copied by clicking the “Copy” icon from the tool bar or using Control+c from the keyboard. Copied elements can be pasted in the same drawing or another drawing of the same Project. Pasting into a new project may cause loss of data.
Always use add an element (drag dropping into drawing) for new projects.
Added elements can be deleted by selecting the element with a left mouse click and pressing either Delete key from keyboard or clicking the delete tool in the tool bar.
It is possible to Delete more than one elements at a time by selecting them and applying delete option. Refer to Selection properties to know how to select more than one element.
Fig.18 Rotating element (in steps of 90o)
Rotation of elements can be performed by selecting the element in the work area with left mouse click and pressing space key from key board.
Elements can be rotated in quantum steps of 90o (degrees).
Rotate option in the tool bar turns active upon selecting at least one element in work area, which can be clicked to orient the selected element(s) to the required rotation.
A number of elements can be selected together by holding control key from key board and left clicking required number of elements in the work area. Once the required elements are selected (evident from light gray box enclosing each selected element), rotation operation can now be performed on all the selected elements together as described earlier. Some elements like for example, a horizontal ammeter that cannot be rotated for obvious reasons.
Fig.19 Rotating more than one element (with and without text selected in steps of 90o)
Clicking the `Selection properties’ tool will pop open a properties window for the selected element.
At a time more than one element can be selected either by holding Control key from keyboard and selecting each element by left clicking it with mouse or by clicking a point in the workspace, holding it and dragging a selection square encompassing the elements to be selected.
When more than one element is selected, the selection properties window will have no options. Or in otherwords the software will not permit defining properties for a collection of elements simultaneously. It has to be done element by element.
Fig.20 Illustration of selecting more than one element with mouse
Folio report is included in the QETCollection –> Electric –> All-pole –> Sheetreferencing in the collection of QET Elements. The element performs the referencing roles in the drawings. Refer to the section Reports folio .
AddaTextfield tool is provided in the tool bar of the main window. To add a text field into the work space
Click the AddaTextfield tool and click at a point in the work space, where the text field should be added.
The text field by default appears as an underscore and it can be either used in association with an element or as an additional field inserted in the work space.
Some elements are provided with a text field at each of their terminals and / or one for the entire element. Additional text fields can be added any where in the work space by the procedure described earlier. The text field can be edited in the work space by
Double left clicking the text field with the mouse and keying in text from keyboard.
To exit editing, click any where else in the workspace. The text field supports multi-line entries and a few formatting options.
All the text fields are horizontally oriented in the work space by default but, they can be oriented in any direction. The text field can be re-oriented by rotating it as described below:
Select the text field by left clicking it with the mouse.
Rotate it with the Rotate tool from the tool bar - refer to section on rotating elements. Alternatively the element can be rotated in quantum steps of 90o by pressing the Space bar from the keyboard.
The text field has special rotation attribute that it can be rotated precisely upto two decimal places of a degree.
Select the text field and press Control+Space keys from keyboard to pop open a GUI window to rotate the text field in any direction.
The GUI window facilitates rotation in quantum steps of 45o degrees by clicking the green squares on the yellow circle.
A double spin box is also provided to manually enter an angle of orientation upto two decimal places. The double spin box can also be interacted with a left mouse, by clicking the up or down arrow keys, to increment or decrement the angles in steps of 1 degree correspondingly with each click.

Text field can be moved any where in the workspace by
Selecting it with a left mouse click and holding it and drag dropping the text to a new position.
Text fields that are associated with the elements require controlkey to be pressed from the keyboard to permit moving its text field along with the earlier described procedure.
Moving an element’s text field produces a blue colored highlight over the element during relocation as shown in the Fig.22. This feature of QElectroTech helps user to perform such actions in a large diagram and still conspicuously keep track of its parent element.

Text fields that are not associated with elements have an additional editing options -
Select the text field with a left mouse click and use the keyboard short cut Control+e or from the main menu bar, select Edit-->Editthetextfield. A simple text editor window opens up to facilitate some basic text formatting features such as increasing the font size, font color, applying bold / italics / underlining formats to texts and inserting a hyperlink.
The hyperlink is preserved only for the diagrams that are exported to `pdf’ format. For other picture exporting formats the hyperlink appears as a underlined text.

Elements have terminals, a conductor generating extension to elements to connect them with other elements or connectors. Making connections between terminals can be summarized as follows:
Position the cursor on the element connector or terminal you want to connect; you will see that a blue dot appearing on the terminals you want to join.
Left click the blue dot and hold and drag the pointer to the connector or terminal to join the other element you want to connect. If a green dot appears on the target terminals, it means that the conductor path between them is complete. A red dot means a ``forbidden connection”.
Release the left mouse button and the conductor will be completed. The conductor assumes a path between the two elements. However, the connectors can be edited by selecting the conductor with a left mouse click and dragging the green squares on it. Refer to Section.8 for more operations with conductors.
Fig.24 Animated graphics showing making of connection (by way of conductors) between two elements(Top) Graphic illustrates that for a connection to be made between the two terminals, blue dot should be selected and cursor should be dragged to the other terminal in a fashion shown by arrows. (Bottom) graphic animates connection between a relay and a push button. When a terminal of the coil is pointed with the mouse, a blue colored dot develops at the terminal tip. The dot turns red upon clicking and holding it. Holding and dragging the dot to the terminal of the push button causes a green colored dot to appear at the terminal of the push button, indicating that the connection is permitted. Releasing the mouse button at this point creates a conductor between the two terminals.
Select a connector with a left mouse click. The segment of the selected connector between two elements turns red, indicating that the conductor is selected.
Position the cursor over the selected connector; you will find thick green colored squares appear over this segment, one each in a bend.
The connector can now be adjusted as per the users demands by left clicking these thick little squares and holding and dragging to a new position. The connector changes its path during this action.
To reset the altered path, left click the short cut icon `Reset conductors’ provided in the tool bar with the connector selected (highlighted red). This action will undo all the earlier changes effected to the connector.
Fig.26 Animation showing adjusting conductors with handles and reset tool
Connectors are provided with text fields, which can be configured from the new project option and conductor tab. Additional text fields can be inserted at desired locations. Text fields for connectors have the same behavior as the text fields for elements discussed under creating a new diagram. Double left click a connector text field and enter the text. The text can orient horizontally or vertically depending on the section of the connector where the test field is provided. The text fields can be rotated and re-positioned as required. Refer section on configure conductor for a complete list of configuration options.
A connector’s properties window can be activated by double left clicking it. The connector and its text field properties can be set from this window. Only multiline connectors have text fields. Selecting the singleline radio button deactivates the text field. The single line option has further options to format the connector as an earth, phase or a neutral conductor or a combination of any. Selecting the neutral option further facilitates formatting the conductor as ProtectiveEarthNeutral (PEN). Number of phases can also be set upto 3 by selecting the phase radio button and using the slider or keying a value into the double spin field. Color and styles to a connector can be applied irrespective of other choices. Refer section on configure conductor.
Element can be viewed as a physical object (component) that is symbolically represented. An electrical, electronic, process or an instrumentation diagram employs a large number of symbols that are linked to each other that forms a system. Symbols can be standard, like those issued by ISA (International Society of Automation), or a custom defined by a design house. In QElectroTech such symbols are called elements. They can be given names to describe them and saved either in a *.elmt or a *.xml format.
Elements in QElectroTech exist in “xml” format. The QETCollection of elements provided with default QElectroTech installation parameters, are saved in a invisible folder $HOME/.qet/elements. User may however save his/her elements anywhere on the disk. But, QElectroTech detects its elements only from this default folder whenever Reload is executed from the Element'spaneltoolbar. Alternatively, users are also provided with a tool in element’s panel tool bar, to import elements from a different folder. Refer to animation tutorial Fig.36 of Section.10.
Elements provided in the QET collection are read only and cannot be edited. However, they can be added to “User collection” and subsequently edited and saved. The animation graphic presented at Fig.36 of Section.10 will explain the steps in creating a new element.
Select the Usercollection with a left mouse click. The elements can be directly created under it. However, it is a good practice to first create a category under the Usercollection.
Left click the shortcut icon Newcategory. Addanewcategory wizard pops open, which will prompt the user of further steps to create a new category. Category is analogous to folders on a disk. Each new category will create a folder under $HOME/.qet/elements.
Enter a name to the new category field (internal name); the field takes only small letters, numbers and `-‘, `_’ and `.’.
The field displays Nameofthenewcategory and language as en for English versions. Additional languages can also be added by left clicking the Addaline button. Double left click the text field and enter a name that the category should display. Hit enter from keyboard. Now left click Ok button to add the category to the user collection.
The new category is added and appears under the Usercollection. Point the cursor to the new category, its internal name is displayed in the tool tip and the text entered in the text field (explained in step 4) will be displayed as its name.
Click on the shortcut icon on the tool bar to create a Newelement.
A wizard pops open prompting the user for subsequent inputs to Createanewelement. Select the category in which the new element has to be created.
Click the Next button. The action prompts for assigning a file name to the element. It is the name of the file on the disk in $HOME/.qet/elements. Overwrite the default filename new_element and click Next to continue. The field accepts only small letters, numbers and `-‘, `_’ and `.’.
The action leads to a elements name field; double click the text field to enter a name by which the element is displayed. The default language is en (english). More languages can be added and corresponding names set by clicking Addaline button. The fields can be edited by a double click. After completing entering the name click Finish to begin drawing the element in the elements’ editor.
The element will be displayed under the Usercollection under the category chosen after it is drawn and saved in the elements’ editor. However, a reload of the collection of elements is required. Refer to the graphic Fig.36 of Section.10.
The element editor facilitates drawing of a new element or editing imported elements. The element editor has a plain drawing area with two thin red colored reference cross hairs, whose center is origin with coordinates (0,0). The cross hair is basically a set of coordinate axes, that helps in dimensioning, positioning and scaling of drawings. However, it does not appear in the finished element. Refer Section.9.2 for a description on elements’ editor.
This is the dotted grid area over which the elements are drawn. The grid area has two kinds of markings . and +. The distance between two consecutive + is 10px and between two consecutive . is 5px.
User can pick up a drawing tool from the drawing tools with a single click. A faded gray cross hair mark now appears with cursor, with its intersecting point at the cursor position. These reference marks assist in the drawing. The information window describes the properties of individual part in the drawing and it is accessible only when the part is selected. The interactive behaviour with mouse in the drawing editor window on a macro level includes :
Selection of drawing parts is possible using left mouse button, in a manner described for selection of elements; refer Selection properties. Individual parts can be selected with a left mouse click.
Mouse middle button can be used to zoom in and out.
Right mouse button click in the window gives access to many interesting functions, that includes most of the keyboard shortcuts described under main menu bar.
Undo & Parts windows are related to each other, in the sense Undo keeps a record of each of the user’s action in the drawing and Parts keep inventory of the parts. A brief use of these tabs are explained here -
User may go back to any previous state by selecting the point in the Undo window. The states are listed in the chronological order with the latest state highlighted at the bottom of the list.
Parts window will show the inventory of the parts in the state specified by Undo. Reverting to a previous state from Undo (by point (a)) will also update the corresponding inventory in the Parts window.
By default the parts tab is displayed. It contains all the individual parts that make up the drawing.
As the complexity of the drawing or element increases, it become easier to define properties of individual parts from the parts window. Select a part from the parts window, its referencing component in the drawing is highlighted in red color (other than texts). User can now define its attributes such as position, color, fill, thickness etc., in the information window.
User can also exploit keyboard shortcuts Del (delete), Ctrl+c (copy), Ctrl+x (cut), Ctrl+v (paste) and Ctrl+z (undo) after selecting a part from the parts window, to speed up his/her work in the elements editor.
Information window displays the properties (attributes) of the selected individual part in the drawing. The properties of each part is its type dependent. However, a few things are common to some common shapes and they are described here.
Appearance (For Line, Square, Ellipse and Arc tools)
The appearance properties for a part are line style, outline color, weight (thickness of lines), filling color for closed geometry like rectangle, square etc., and antialiasing, which is to remove distortions of the skectches and smoothem for better smoother appearance.
Outline color specifies a color for the lines of the part selected. The selected part can be any geometry such as an ellipse, a curve, a straight line or a rectangle etc.,. There are five colors that a user can choose from namely - Black, White, Green, Red and Blue.
Filling lets user to fill colors in the area bounded by the part’s closed geometry such as a triangle, square, ellipse etc., User can keep the bounded area transparent by assigning None as the filling option or choose a color from Black, White, Green, Red and Blue.
Line style describes how line(s) should be displayed for the part selected. Options include
Normal: Straight continuous lines
Dashed: Dashed lines
Dotted: Dotted lines
Dots and dashes: One dot followed by a dash and repeated.
Weight defines the thickness of the line segments of the selected part. The options are qualitatively provided in QElectroTech such as None, Thin, Normal, Strong and High.
Antialiasing is an option to remove distortions from the selected part. Some lines (especially slanting) appear with stairstep-like distortions at the edges, referred to as jaggies in computer graphics. These distortions can be minimized by choosing this option.
Geometrical properties for a part varies with the part selected. A simple line, a square or a rectangle, a circle, text fields, a terminal and an arc will have their own set of specific parameters, which are displayed in the information panel. Try drawing each of the drawing tools in the work area and select them to check the information area. Watch how the parameters change with each geometry. Try changing the parameters from the information window to note their effect on the part in the drawing.
Active area is the part of the element that is selected with a left mouse click. The active area attributes (properties) are displayed in the information window and the segment will be highlighted in the parts window.
The following actions will describe a general behaviour in the elements editor. An instance of usage of a drawing tool is referred to as a part in the elements’ editor.
Drawing tools can be selected by a single click on the tool from the drawing and labelling tool bar.
Deselecting the tool is possible either by pressing Esc key from the keyboard or using a rightclick with the mouse.
The entire element or each drawing part can be selected using left mouse button. Single part can be selected by left clicking it (no drawing tool should be active). Multiple parts can be selected as described earlier under Selection properties. Selecting the part(s) creates a rectangular dotted box with small square handles around the object(s) (part(s)), which can be dragged (click + hold and move) with mouse to scale its size. The selected part(s) can be repositioned anywhere in the drawing area by drag dropping with mouse.
While working with the Addapolygon tool the following points should be kept in mind:
User must use a double click to complete one instance of drawing.
User must checkout the closedpolygon option in the information panel, after completing a geometry to achieve a truly closed geometry. Options like filling with a color is possible only with closed geometry.
A right click un-does the last action.
The option closedpolygon can produce a closing line. For example, While drawing a triangle, a user can actually leave the tool after drawing a “V” shaped geometry and click closed polygon to complete the third side.
There are two tools for adding text to the drawing - Addatext and Addatextfield. Addatextfield has few additional options, namely Tag and Donotfollowparentelementrotations and a defaulttext field. The specific purpose they serve are enumerated here
Every drawing or element requires at least one text label, which is achieved with Addatextfield tool and then tagging the field as label from the combo-box in the Information window.
Addatextfield provides a text field with the element which is editable in the QElectroTech main drawing window. But, the Addatext field is used to add permanent text to the element. This field is not editable during the element usage in the main drawing window.
Checking out the option Donotfollowparentelementrotations will fix the alignment of the text field during its usage in the QElectroTech main drawing window i.e. if the element is rotated in the QElectroTech drawing area, the text field orientation remains fixed and does not follow the element.
The text fields cannot be resized by dragging the selection handles. However, the font can be adjusted from the information window, by choosing a font size.
The drawing bar has a set of tools like a line, rectangle, ellipse etc., for constructing an element. Each instance of usage of a tool is called a part. Each tool has its characteristic properties displayed in the Information window. Refer to section on Geometry to know in detail about specific features of the corresponding tool. In the following topics, detailed procedure to apply each tool is described.
Use a left mouse click to select and activate the Addaline tool from the drawing bar. From basics of geometry we know that a straight line is defined between atleast two coordinates. In the elements editor, we use left mouse clicks in the drawing area to select two coordinates to define the line segment. The line segment can be re-sized either from its information panel or using the sizing handles from its activearea. Drag dropping a line segment, to move it to another location in the drawing is also possible.
Fig.28 Line tool and formatting:
The line segment information is shown here in Fig.28 . The line segment geometry can be defined by a start coordinate and ending coordinate. The default end style is normal; optionally the endings can be set as a simplearrow, trianglearrow, circlearrow or a diamondarrow. End 1 is the initial point from where the line segment is drawn and End 2 is the ending point of the line segment. The triangle, circle and diamond arrow spaces can be filled with a color using the Filling combo box; the default is set as None indicating transparent. The line color can be set from the outline combobox. The options available are black, white, green, red or blue. The line style can be normal (continuous black line), dashed, dotted or dashed&dotted. The thickness of the line segment can be defined from the weight combo box. A slanted line can have rough outline with stairstep-like distortions, which can be smoothed by selecting the anti-aliasing option.
Select Addarectangle icon with a left mouse click from the drawing bar to activate it. Use left mouse clicks to select two points that would become to top left corner coordinate and bottom right coordinate in the drawing area for the rectangle. The rectangle would be generated and it can be also be re-sized from its information panel or by using the resizing handles from its activearea. The rectangle can be shifted to a different position in the drawing area by drag dropping it to the other position.
Fig.29 Rectangle tool and formatting:
The Rectangle tool permits drawing of rectangular geometry in the element editor. Formatting options that are provided (information window) for a rectangle are tabulated under Appearance and Geometry. The geometry is defined by a point and the size of the rectangle (length and breadth). The appearance options are similar to those available for line tool.
Elements require terminals to provide for connections with other elements in a circuit. Terminals offer an interactive point in the QElectroTech main drawing area, to create conductors between other terminals of either the same element or another element. The terminal tool in the elements editor provides for creating or rather adding terminals to elements. Click the red-blue (colored) terminal tool from the drawing tools bar to select it. A terminal is created at a point in the drawing area with a left mouse click. Several elements can be added with subsequent left clicks as long as the tool is selected (active). The terminal is not scalable but its orientation can be changed from the information panel. The blue colored square on the terminal corresponds to its position in the drawing.
Fig.30 Terminal tool information:
A terminal has a fixed set of dimensions and cannot be changed. It has a special directional property (orientation) and is specified as North, South, East and West, from the information panel. This direction is determined by the blue square of the terminal, in the direction that it points relative to its red tail. It is described in the working area by a single coordinate, the point where it is added (blue square). The red tail of the terminal should be placed inside the element geometry. The terminal gives the element an interactive property in QElectroTech main drawing area. Refer to the animation describing creation of connections in Fig.24.
Select the Addanellipse icon from the drawing bar to activate it. Use a left mouse click in the drawing area to select a point to start drawing with the tool, click a second point to form an ellipse. The ellipse can be re-sized either by using re-sizing handles from its activearea or using its information panel. Drag dropping the ellipse to shift to another position in the drawing area is possible.
Fig.31 Ellipse tool with different format options:
Ellipse tool permits drawing ellipses and circles in the drawing editor. The geometry of an ellipse is defined by the center point coordinate and its horizontal and vertical diameters. Standard line formatting styles are possible with ellipse tool. Some of them are illustrated in the Fig.31 . Anti-Aliasing option can be applied to smooothen the ellipse. This option is deselected for some of the illustrations shown in Fig.31 (zoom to view closely). For a range of ellipse properties in the elements editor refer to Appearance and Geometry.
Select the Addapolygon tool with a left mouse click to activate. With the tool activated, use left mouse clicks to select a number of points that define the polygon in the drawing area. A polygon is formed by straight lines forming between to consecutive clicks. To finalize the geometry, use a right mouse click. To deselect the tool press Esc from keyboard. User may subsequently re-size the polygon using the handles from its activearea or from its information panel. A seemingly closed geometry created using mouse clicks may not be a truly closed geometry. The option closedpolygon should be checked-out in the information panel to achieve a bounded figure. Refer to the topic working with drawing tools to know more about using this tool.
Fig.32 Polygon tool in different formats:Addapolygon tool is flexible tool to create varied geometry. It is a handy tool for creative users trying to sketch complicated symbols using the elements editor. Some sample sketches are drawn in Fig.32 to display some of its capabilities. The geometry of a polygon is defined by two columns of coordinates for x and y, which are created for every left mouse click in the drawing area. The appearance properties are same as that of a line tool. For more information about using this tool refer to working with drawing tools , Appearance and Geometry.
Select the Addanarc tool with a left mouse click to activate. With the tool activated, use left mouse click to select two points between which an arc is created. The arc tool draws an ellipse and crops it between the two points that were selected with mouse. Its geometry in elements editor is described by a center point, horizontal diameter along x-axis and a vertical diameter along y-axis and the angle between the first and the second clicks between which it is cropped. The arc may be re-sized using the handles from its activearea or from its information panel. Arc tool has anti-aliasing as its default option for smoothness.
Fig.33 Arc tool with some formatted styles:
The arc tool permits creation of an arc along an elliptical path. Some samples using arc tool are drawn in the Fig.33. The appearance properties for arc are same as that of a line tool. Drag and drop functions are possible to move the arc in the drawing area. Refer to sections on Appearance and Geometry for more explanation.
Some elements require a name to be associated with it. Addatext tool permits inserting such text with an element. It can be activated by a single left click on the Addatext the tool in the drawing bar. Select a point in the drawing area by a left mouse click to insert the text field. Text can be entered from its information panel. Few basic formatting options are also included such as font size, color, orientation etc.,. The add text field is used to label the element or its components and it cannot be edited during the elements use in QElectroTech main drawing window. Also refer to sections on working with drawing tools , Appearance and Geometry for more information.
Fig.34 Text tool and information:Addatext tool permits fixed naming of the element or its parts at the time of its drawing in elements editor. Add text appears as a text box with a default text T. The text can be resized from the font size field in its information panel. Drag and drop functions to reposition it in the elements editor drawing area are provided. The information panel describes the text box position by a single point coordinate, font size, color, text to display and orientation. Text can be set in any direction from 0 to 359.99o (degrees). The Fig.34 shows text QET added to rectangles filled with different colors for demonstration.
Select the Addatextfield tool with a left mouse click to activate it. Use left mouse click to select a point in the drawing area to add a text label. A text box with a default font _, appears at the point selected. The field size is defined by the font size and can be set from its information panel. The add text field should be included as a label to the element or its components. The field is editable during its use in the QElectroTech drawings unlike the Addatext field. User may add information to the element using the field, while working with it in the QElectroTech main drawings. Also refer to sections on working with drawing tools , Appearance and Geometry for more information.
Fig.35 Text field inserted for an element:
Every element requires at least one Addatextfield, which is tagged as a label from its information window. Drag and drop functions are possible for this field in both elements editor and in the QElectroTech drawing window independent of the parent element. The information panel describes the text box position by a single point coordinate, font size, default text as _. Add a text field can be oriented in any direction possible from 0 to 359.99. The Fig.35 shows the Add a text field in its default appearance. The tool has an additional option of Donotfollowparentelementrotations to lock its orientation in the QElectroTech drawing window. With this option selected, the text field does not rotate even when the parent element to which it is associated is rotated in the QElectroTech drawing.
10. Sample tutorial - Creating a Globe Valve Element¶
The tutorial here explains the creation of a globe valve element. You may click on the animated graphic to zoom to understand the sequence of steps followed to create and import elements in diagrams. The graphic is provided with text to offer guidance to each action required in the stage.
Fig.36 Steps for creating and importing elements in QElectroTech (Right click the image and select view image to watch the animation in full screen)
QElectroTech comes with six different templates to work with, namely - A4\_1, default, DIN\_A4, double-logo, ISO7200_A4_V1 and singlelogo. QElectroTech also permits custom template designing with user defined title block. The default template loads with a new project, this is the default setting with the QElectroTech. The user can apply a ready to use template from options provided or can also edit a template after it is imported into a drawing, when it appears in the tree - embeddedtitleblock under the project in elementspanel. The templates behaviour is much like the actions of other elements, a template can be applied to the current drawing by drag dropping it on to the drawing area from the elements panel. Alternatively, users can also choose a template to load with each new drawing created in a project refer to information title block of Section.4 . This attribute can be set from the projectproperties window with newfolio tab.
In this section, an introduction to the title block editor is presented. Also, a tutorial to design a referenced title block is included, to familiarize users with the behavior of the title block editor.
Right click in the drawing area and select the folio properties from the options
Double click the title block of the drawing
Left click `Folio properties’ button on the tool bar
On the folio properties window, under the section `Informations title blocks’ click the drop down box next to the template field and select `Edit this template’ option . After completion, save the template with a suitable name under one of the categories available. Further, it is possible to use different title block layouts for each drawing within the same project.
QElectroTech will not permit editing the master templates provided under the `QET Title blocks’. However, a user can import one of the template to his/her collection and edit the template as per the requirements and save it for subsequent use.
A suggested sequence for creating a customized template is illustrated here in snapshots.
(1) Launch QElectroTech application(2) Right click a suitable template and select `Edit this template’ or a double click also will do(3) Template editor opens the template with read only access(4) Click `Save as’ option
(5) Save as window opens up with default values(6) Set `User title blocks’ for parent collection option and give a name say `My company’ to save the template(7) Template editor saves the template copy by the new name `My company’ under `User title blocks’ and this is editable(8) You can now figure out this `My company’ template under “User title blocks”
