Frequently Asked Questions

How do I run the build of Ondsel ES for Windows?

After unpacking the 7zip archive, please navigate to the 'bin' folder and double-click 'freecad.exe'. This is a temporary workaround. We will provide an installer soon.

We are in extended validation process, we will sign our builds as soon as we get the token.

Is there a tutorial for using the integrated assembly workbench?
