If you check out the Bryce forum this evening (see the list on the right and go to Bryce--we need more posts over there anyhow), I'll try to do either a printscreen or save the image of the meshes of these-perhaps you can see what I did. Its really not hard once you get the gist of how the boolean thing works-however-all this really belongs on the Bryce forum, not here-sorry. Diane
