Hi mjs, if I understand what you are asking correctly - yes there is a tolerance involved when testing for surface/surface coincidence as well. But usually it helps with various mechanisms if overlapping areas are within a pretty tight tolerance, if they wiggle through each other by too much it can be detected as a complex intersection rather than a overlap/coincidence type situation.

Hi Michael,

It is exactly what i was after. In Spaceclaim there is a command called Inteference (or something like that) that point and - if you want - fix it, but in Moi i just need those areas to be pointed out.

Thanks a lot.

Cheers
