<<I, too, have been having a lot of problems with boolean and flipped normals. What I don't understand is why object unify doesn't seem to correct this. Because of this "bug" I tend to avoid using boolean operations altogether.>> Object Unify does not always fix the problem, not becuase of a bug, but simply because of the position of the face in question. The algorithim will look at a certain face, and based on its position and relation to the bounding box and center point, will determine whether it is facing inward or outwards. <<Also, I think it is a poor policy to suggest that the solution to a bug like this is to use ACAD. If boolean is in 3DS then lets just fix it so it works>> The boolean functionality between ACAD and 3DS are very different. The 3DS modeler was not designed as a full function Boolean editor. It is a question of using the right tool for the right job. If you need to create complex booleaned objects, you need to use a full function boolean editor. -Brian
