Hi John, I've tried multi-segmenting the background object to no avail. That works on basic shapes it seems but not on more complex ones. I've gotten around the problem temporially by repairing the carved object after the boolean subtract (whew!). I've noticed this problem even when I try to carve two box type shapes. Sometimes it works without a hitch and sometimes it doesn't. Weird heh? Has anyone in this forum had this problem????
