Can't save after use of thickness on loft

[DeepSOIC]

For me, it only reported a bunch of C0 geometry. That isn't a problem... usually...

Really? I'm getting an invalid solid with the Part Thickness (2mm outward, Arc join type) from the OP's file and mine.

Really.
But I'm on OCC 7.2, not 7.3 as you are.

Really.

I wasn't doubting you, just surprised.

I just checked with the FreeCAD 0.17.13522 AppImage (with OCCT 7.2.0), CheckGeometry reports the Solid as "Invalid", but below it reports BOPAlgo_GeomAbs_C0 for 4 of its faces.

Very odd that the message is changed in 7.3.

... Anyway there should be a freecad bug reported against check geometry to update the error messages. I implemented the error messages as a const list and then indexed into that list using the enum. That was a poor decision. The errors should be in a map and the enums as a key and that would at least avoided this confusion.

Thank you all for response and help. I tried Mode to "Skin" + Join type to "Intersection" - that is combination that works.

I also tried to do some modification on part before use of thickness, but that cause new problems - setting of Join type cause hang (test_2 file). You can try it on your Ubuntu, it could be some Windows problem. But I can do thickness on base part as you suggested, it works great, so my problem is solved. I am triing to make camera lens hood for 3D print.

Thanks to NormandC for file with geometric constraints. I'm learning the program for a few days. I have some experience with CAD programs, but it is almost five years when I did something, so I am exploring now. It is amazing what FreeCAD can do.
