Problem description

When padding a face in the UpToFace mode, if the boundaries of the face to be padded exceed the face to be padded up to, FreeCAD LinkStable breaks with the following error message:

Document.cpp(3424): Failed to recompute Test#Pad001: BRepFeat_MakePrism: extrusion failed

When trying the same with LinkMerge, the pad works as intended:

Anything else?

Please try the flatpak build in my release. I packaged a patched version of OCC the CAD kernel library. In next release, I'll try improve compatibility with the official OCC.

Thanks for the quick response, the Flatpak from https://github.com/realthunder/FreeCAD/releases/tag/20240407stable works with the given example. The about page for it states OCC 7.7.2 (patched or not), while my Flatpak still has OCC 7.6.3, so I'll need to update that first to see if it fixes the issue. I presume your patched OCC lies here, so I can also test that until upstream compatibility is improved.
