You may have noticed, that I rewrote the whole application to C++ and released that code in October 2022!
From that time there were many updates to the C++-code: Latest in December 2025.
Only the subject of this forum-thread is left to original...

Additionally you do not need to compile it yourself, if you use ReactOS, win or Linux: There are binaries available in Release-section of my GitHub-repo.
EDIT:
Even back in the days of Pascal code, executable files for ReactOS, win and Linux were already available, so there was no need to compile them yourself!
Have a look here: https://github.com/plc-user/QET_ElementScaler/releases

You are expressly permitted to use the existing C++ - code of QET_ElementScaler to implement mirror and flip to QET!

Hello,

on last version 0.100.0 be able to flip or mirror a symbol of an electrical component vertically or horizontaly on element editor without need to add plc-user's plug-in.

Installing plug-ins in the element editor in version 0.100.0 is very straightforward: simply click on the File menu, select ‘Resize an element’ or ‘Import a DXF file’. You will be guided through the download and installation process. Just extract the binary maybe rename it, and put it in binary folder asked by widget.

Bonjour.
The request to be able to flip a symbol of an electrical component vertically or horizontaly has been on this forum since before 2014.

Thanks, Scorpio 810 [24 July 2025], but at 75+, having to set up a whole development environment and learning Pascal just to do all this work is becoming too much of a hassle. For me, it would be fine if it were in C or C++.

I find it hard to believe that, after 12 years at least, one of the latest versions of QElectrotech still hasn’t addressed such an important request.
Why?

Thanks for the information!

That is good to know:
Then I can save myself the effort of building and uploading these packages in future!
As written in release-section:
I can't test the macos-binaries myself anyway. And if they don't work, I don't need to create them any more...

I build new QET_ElementScaler 0.5.4 macOS aarch64 binary, because binary provided by plc-user didn't work!

Hallo plc-user,

I tried your macOS aarch64 binary on new UTM virtual machine:
https://github.com/plc-user/QET_Element … /tag/0.5.4

The binaries for macos are to be seen as a “trial version” to see if the toolchain from the Docker image works, I don't have the possibility to test the executables.

FYI, QET_ElementScaler was saw as a document, so chmod +x QET_ElementScaler but binary crashed with:

Hello everybody!

Maybe you already noticed?

Available in current 0.100-dev-version of QElectroTech:
In the last few days I implemented mirror (shortcut ) and flip (shortcut ) into element-editor.
Also the rotate-function was reworked, so that rotating of ALL primitives is made in increments of 90° with .
Rotation with smaller increments of 5° can be made with "text", "dynamic_text", "line" and "polygon" with +.

"Merci" to Laurent, who supported with building all binaries!

Merci pour l'aide, j'ai en fait assez de puissance, vous pouvez créer mes composants et les adapter à ceux que vous ne souhaitez pas, et mes plans électriques sont ceux que j'aime. Salutations et merci d'avoir créé ce programme incroyable !

Did you notice the menu-entry just below "Import scaled element"? (see attachment!)
AND: Use the conversion-tool dxf2elmt! The other tool is VERY outdated!
You find the download-link for win64 in this post: https://qelectrotech.org/forum/viewtopi … 520#p20520

What do you want to do?
QET works with own file-formats for elements and schematics!

I think, many of your questions about scale and dxf-import will be answered, if you read in the other thread and follow the links there:

I appreciate the prompt response provided, I was able to install the qelectrotech plugin satisfactorily, now I have another couple of questions, I hope this doesn't sound overwhelming.

1.What is the correct way to create a new element from a DXF?
I am currently importing my DXF to the new elements editor in qelectrotech, to be able to add the necessary connections, but I see that the DXFTOQET tool is suggested in the forum. Does this program perform the same procedure or does it perform any additional processes?

2.What scale does Qelectrotech work on?
Currently, from the element editor I exported a DXF with measurements of 100mm 27mm (100 X 49.92mm).

As the name QET_ElementScaler might suggest, only QET-Elements can be scaled by that software!
You need to convert your dxf to a QET-Element before using QET_ElementScaler!

Hello,

in last version 0.100-dev "Import an element to resize" was implanted directly on element editor, no need to use terminal if you want.
See the plc-user's quick-guide -> https://download.qelectrotech.org/qet/Q … ick-guide/

https://qelectrotech.org/forum/viewtopic.php?id=2795

For installation and can be launched in element editor it's the same way like dxf2elmt install see:

Hello everyone, I have many doubts regarding the use of this program, I am not an expert in program issues and their execution at the CMD level, but I need to scale a DXF so that it is the actual size of the design, qelectrotech makes it smaller. Could someone tell me how to use this program properly on Windows, please?

There are several new topics for me at once:
For the beginnings in Pascal I only needed to add a little XML to the Pascal knowledge. The change to C++ was then already bigger. But then to integrate that into an existing, grown QT project, that's quite another matter...
For the moment I have put together a small (and from my point of view) usable package. There is no question that in the foreseeable future it will make sense to integrate scaling and mirroring directly into QET's Element-Editor!

Bravo plc-user! QET becomes more and more appealing by the day - many thanks for your great work!
