So you can first remove the overlap from each part. union() { difference() { ObjectA; ObjectBWithoutHoles; } difference() { ObjectB; ObjectAWithoutHoles; } } This is only a sketch. The rotates and transforms have to be duplicated in the relevant locations. As written it would probably create a non-manifold surface where the two touch; you should probably scale down or move the subtracted objects so that the union ends up overlapping the the resulting objects by a tiny amount. In creating "ObjectXWithoutHoles" you could simplify it further; in some cases a bounding cube would be good enough. -- View this message in context: http://forum.openscad.org/Logic-operation-among-objects-tp18725p18727.html Sent from the OpenSCAD mailing list archive at Nabble.com.
