Hey Michel, I've never been able to stand people complaining about Moi3D's bevels/chamfers in the past either, actually, I think I even posted something about it once, explaining that you could do bevels using surfaces too. So when I said Moi3D doesn't do bevels either, I was specifically talking about that model (crash1.plasticity), nothing more.
That said, I just tried again with the latest stable version, Plasticity 25.3.4, and I managed to reproduce the issue.
Anyway, I gave it another shot and was able to recreate the problem.

P.S.
I never badmouth other programs, I've never done it and I'm not about to start.

Cheers and happy holidays!
