Frequently asked questions and answers

In File – Options – Data Fields I entered values for the „title“ and „titleSup“ fields, but they do not appear in the title block.

These two fields are different for each page. That is why they need to be entered in the Page panel (double-click the page). If you want these two fields to be the same on all pages, enter them in File – Options – Data Fields and delete them from the Pages panel.

At program startup there is no grid nor any page frame

Go to program settings (press F12), select Document - Size, "According to Printer", press button Setup and select the paper format you wish to use.

How to setup numbering of a symbol, for example to be W1, W2, W3 instead of R1, R2, R3

  1. Open the symbol (right-click the symbol in panel "Symbols Graphically" and select open symbol)
  2. Press F12 and select Symbol
  3. Change default reference
Also, see this video.

Message "out of memory" appears

This may happen if the drawing contains too large images (data size of many MB). There are two possible solutions:

  • Use the menu command File - Purge. This will delete unnecessary objects from the drawing.
  • Remove the images from the drawing, edit them in a graphics program (to have smaller size) and insert them again.

My line types disappeared - I can only see a solid line

The symbols library must contain folder _LIN with a file lines.lin . You can determine the path to the library in program settings (F12) - Paths

There are several objects on my page but I cannot select anything

The objects may be in a different layer. Switch into the right layer.

How can I add symbols to the favorites pane?

Drag them onto the heart icon.

How to import from PDF?

PDF can not be inserted directly into a ProfiCAD drawing. One can take a screenshot and then insert it as an image.

How to export to PDF format?

For export to PDF we can recommend programs like:

Foxit (

and many others

These programs operate on the principle of virtual printers, i.e. in ProfiCAD choose to print and select one of these programs as a printer. Additionally, select paper size, page orientation and location on the disk where to save the resulting document.

You may also use the "Microsoft XPS" format, which is Microsoft's alternative to PDF. The advantage is that it is pre-installed in Windows already. XPS documents can be opened on any MS Windows computer.

Sometimes there is a need that the arrow is pointing backwards and has to be drawn again.

To reverse the arrow, select it by clicking on it and then select a link flip arrow at the bottom of the Properties.

What symbols are available in the full version? Do you have other symbols?

The full version contains the same symbols as the home version. The symbols library is being enhanced continuously. You can easily create symbols in the ProfiCAD symbols editor.

You can find additional symbols on If you created symbols on your own, please consider submitting them to the library.

If I modify a symbol in the symbol editor, will this symbol be changed in all diagrams I have already drawn?

No! It is not possible as each symbol is stored as a unique copy in every diagram. Your diagram is therefore independent on you library of symbols and it can easily be transmitted to anyone else. This applies for versions 3.0 and up (for IC versions 3.1 and up).

When I attempt printing the diagram on the 5L laser printer, some lines blur and some parts of the diagram are not printed at all.

Adjust the resolution of your printer from 600 DPI to 300 DPI (see Printer property settings).

Dashed line prints as solid line

Invoke Print (by Ctrl + P or the Printer icon)

The next step is somewhat different for each printer.

Click on “Properties” Click on “Advanced” Locate “Print Quality” Locate “Resolution” Find the “Vector” and “Raster” options, select “Raster”

An object cannot be selected - when clicking on an object it cannot be selected and a different object, further from the pointer is highlighted instead.

When creating a symbol, graphical shapes need to be placed in a symmetric way, so that the symbol is symmetric to axes of the working screen.

Correct Incorrect

A yellow frame, which is much larger than the circuit symbol itself, appears around the circuit symbol.

The problem can have two causes:

  • Various artefacts (e.g. very small lines, forgotten outlets, etc.) have arisen during the creation of the circuit symbol, which have been overlooked. The result is that the circuit symbol appears larger, because the surfaces of the frame are also included. The solution is to remove these artefacts, preferably with the aid of Panel Explorer. Should that be the case, the circuit symbol is to be replaced in the circuit plan by a corrected circuit symbol.
  • The circuit symbol is not drawn in symmetrical to the axes of the work surface. The solution is to draw the circuit symbol symmetrically.

Can I customize the gates? When I insert a gate, the program lists only the default gate symbol to select and I have not found a way how to customize it.

After you insert the gate, press the Escape key (to make the cursor change to arrow), place the arrow over the gate and click the right mouse button. A dialog box allowing you to customize the gate parameters (number of outlets, gate type, etc.) will appear.

Program Relocation

If you need to move the program to a different directory or a new computer, just move the above mentioned files. It is not necessary to reinstall the program. The program may also be run from an external hard disk or a flash disk.
