Hi ale,
Welcome to the forum.
Please post your ViaCad file, the screen shots were blurry
when Zooming in.

did you check the preferences: imperial ./. metric ?.....inches ./. millimeters ???
best regards !

If I save a new file as vc3, the unit and measurement are correct again when I open it. I save as dwg or dxf for example it is 25.4 x more. but the default settings are set to mm and when exporting to dxw or dwg it is also set to mm. :(

Hello and thank you for the answer.

Now in notepad I can't find any information about the dxf being in metric like you did. I just tried again to draw a circle with 60mm and then export it as a dxf. After opening it again, the language was changed from German to English and everything was set to inches again. Then I closed it without saving and then everything was back to mm and German as set.


At the same time, the circle in the DXF is not saved as 60mm but as you can see as 1524mm.

How can that be and where is the error? The support from Punchcad itself seems to be awfully bad to me.

What do I have to do?

If someone speaks German and can help me then also in German.

I've been trying to solve the problem for a day but I just can't seem to get it right. Every time I export to DXF or DWG it is saved x 25.4 larger. Except in the VC3 file it stays as it should.

It's also strange that every 2-3 times the program starts in English and not in German as set in the default settings. That's why it always sets it back to inches.


sollte jemand deutsch sprechen und kann mir helfen dann gern auch auf deutsch.

Ich versuche seit einem Tag, das Problem zu lösen, aber ich kriege es einfach nicht hin. Jedes Mal, wenn ich in DXF oder DWG exportiere, wird es 25,4 x größer gespeichert. Außer in der VC3-Datei bleibt es so, wie es sein soll.

Es ist auch seltsam, dass das Programm alle 2-3 Mal auf Englisch startet und nicht auf Deutsch, wie in den Standardeinstellungen eingestellt. Dann ist es auch wieder auf Zoll zurückgestellt :(

have only viacad 15.. and with viacad 10 i have no one time this problems.

I'm still on V14 and have had issues like this in the past.
In 14 preferences are very flakey, things often don't stick.
I always do a quick check to see that I'm working in metric.
I then check that in the inspector panel under value, then standards I have my settings selected.
Lately every time I start a new project or load an old job it defaults to ANSI.

I think windows upgrades cause a lot of the problems because it used to work but something changes whether its the graphics drivers or windows upgrades, I don't know.

Just a thought,
Perhaps try and export or save as a v10 file.
And see what it does when you reopen it.
Might be a workaround for now and hopefully they fix it.

Hi Ale.
Because its v15 I cant open your files as I use v14.

Another random thought.
If you are trying to rescue your files, Could you use the scale tool?
Draw a 60mm line, select all to be scaled and scale it to the 60mm line.
