OCCT7 +TBB

Good morning
Yesterday I've changed to the PPA freecad-stable, and installed occ 7.2.
I can see changes in multisection, at least. Very subtle changes in its behaviour, breaking my scripts which were working perfectly with occ 7.1.
Excuse me for my poor description. I hope the next days to have a better understanding of the issue.

Hi damian.

I can confirm different results when OCC 7.1 or OCC 7.2+ being used. I don't feel this results are related to BOA "multiple arguments" methods as discussed in this thread. In your example you don't use them anyway. You would need to provide the shape(s) as a list or tuple to do that. Therefore they have likely changed something in OCC. Might be intentional change or they introduced a regression.

P.S. Just noticed another thread that might be related:
