Add faces problem for internal profiles

[gdo35]

Hello,

I have problems to generate internal profiles.
When I select the four faces and click on add button, faces are not added to the profile operation and the following error is displayed :

Code: Select all

Can't find Origin for "Part"
Can't find Origin for "Part"
Can't find Origin for "Body"

CommandManager::addTo() try to add an unknown command (Path_ToolLibraryEdit) to a widget!

I made a video to show the problem :

Hi,

If I use libarea instead of OCC Native, the bug does not seem to happen... (as I am not on the same computer, I'll have to confirm this)
But is it "good" to use libarea instead of OCC Native ?

Just saw your post now. I don t know much about the programming side of freecad but I have found lib aria seems to give more consistent results and better cut paths.

Hi Linden,

Thanks, I only use libarea now.
g-code seems ok even I did not test it on my CNC.
