Hi Michael,

I've just tried to create something similar to your example above, but Boolean Union doesn't seem to work after selecting the bar and the outer shell of the cup-like solid.

I've attached the MoI file.

Thanks,

Metin

Hi Metin, thanks for attaching the problem file. That seems like it should work, I'll investigate why it isn't.

Hi Metin, it seems to be getting confused when there are some vertices (ends of edges) right in the intersection zone.

I'll investigate it some more to see if I can make that work better, in the meantime if you rotate your sphere piece in the front view by 90 degrees (as in the attached example file), it should then work ok.

Thanks Michael. Glad I could give you a pointer to a possible problem case for the new face Booleans.

I've been able to investigate the case you posted, and I've got it fixed up so it will work properly in the v3 final version.

It had to do with some additional processing happening with coincident surfaces (the 2 overlapping planes in your case here) that could end up making some intersection results outside of the subset area, confusing the boolean mechanism.

Thanks for posting the problem file!

You're welcome, Michael, and great to read that it'll be fixed in v3. And a tap on the back of the current MoI for not crashing or freezing in such a case.
