Hi, I have to create a 3d complex geometry using boolean operations between volumes. It works good for some volumes but for others gambit want's to create the intersection ( surfaces ) and everyting goes like the volumes are not intersecting. In other words it seems like the solids haven't a portion in common, but shading the drawing everything seems ok. Is this a bug or I made a mistake? The geometry ( 2d) is imported fom an iges file but I tried also creating that in gambit.

i don't know your problem is but maybe your volume isn't intersecting at all.
