Boolean Difference

Rhino Rhino for Windows

Hi,

I would like to ask when Boolean difference fails and to avoid these cases.
I have a case below that is not possible to cut from the grey geometry (Rhino File attached).

Could someone give guidelines considering tolerance and cases that would work?
I was trying to find an error prone process for boolean difference for quite some time, but always there are cases where it fails. RhinoCommon behaves the same. I do not mind waiting for a longer time, but I really need cut volumes that are often coinciding with existing edges or surfaces.

Yes, what did you do to make it work?

Just use boolean split instead boolean difference. That’s what I used.
