Hi all,
I've read on the forum about problems with using the boolean Cut operation on tangent faced solids. Now I've encountered my own little problem. I have two solids (see attached image) from which one is a hexahedron (1: blue, translucent) which should be cut from a more complex solid (1: red). I imported these solids into DRAW (2) and ran
> bcut result a_1 a_2
The result is shown in (3). It looks like the boolean operation was successfully, but the w r o n g boolean operation was performed. Anyone any idea on this?
Thanks,
Dennis

Okay,
this error also occurs in another CAD program which is based on the ACIS CAD kernel. So it's something wrong with the geometry/topology, though the standard tools for error recognition fail to find any errors.

Dear Dennis G.
The images attached can not clarify the problem.
Could you attach the compound "a" instead.

Problem solved. Thank you for your attempt to help me.

Are you sure that you don't swap the arguments in the command line? Is a_1 a red shape and a_2 a blue one?

No, the arguments weren't swapped. The solid was all wrong, although I do not know which part exactly. The solid had a negative Volume and as I've said in a previous post, the cut result was identical in another ACIS-based CAD-software. I asked my CAD designer to renew the solid and suddenly it worked flawlessly.
Thanks for your idea,
Dennis
