I have a student version of Autodesk 3d Studio, but the instructions are pretty skimpy. I was just wondering why the program, at times, will not subtract one object from another, but requests a change fo geometry.

David The student version of 3DS is release 2 and boolean operations can be very fussy. Try to tesselate the objects so that each object has about the same number of faces and avoid trying it on object with long thin faces. Good luck TedB -Ted Boardman !^NavFont01F0007MGHHGC3200C

YG sent some interesting material to me on this a while back. It basically biols down to the skinnier and longer the face being intersected, the less likely it is to work. Sometimes the tesselations work, sometimes not. There are others who are more fluent at describing what steps can be done to get around this flaw, but I reccomend trying to use booleans as little as possible until r5 comes out. Booleans in 3DS are, thus far, inhernetly limited. It's one of the greatest weaknesses of the program. R5 SHOULD be better, however, with as many people screaming to correct this as there have been.
