CAN ANYBODY HELP ME, I HAVE GOT A VERY MAJOR PROBLEM, I HAVE CREATED A SURFACE REVOLVED OBJECT WITHIN 3D STUDIO, AND THEN CUT HOLES OUT OF THE SIDE OF IT, BUT IT HAS LEFT SOME FUNNY FACES WITH A DIFFERENT SHADE OF THE SAME COLOUR. I THOUGHT THAT SMOOTHING GROUPS MAY RESOLVE THIS PROBLEM BUT IT DIDN'T. ANY THOUGHTS AT ALL WOULD BE VERY WELL RECEIVED AS WE HAVE A VERY TIGHT DEADLINE TO MEET. THANKS.

Hard to tell excatly what's going on with your file, Phil, but I'll give it a couple of shots…*Some* of the problem may stem from a coincidental vertice thing happening in the center of your SurfRev object. Zoom in and select all the vertices in the center, Weld them, and then Boolean your object. If the "changing colors" problem shows up after Booleaning, this is just a artifact of the process. If it is just colors that have changed, and not the edge-sharing faces ability to "smooth together", then simply select the faces in question and apply the appropriate material. Hope you get some ideas from this, -Alan Iglesias

Phil, It doesn't sound like a core vertice problem like Alan suggested – but you never know. It sounds like you are just booleaning with objects that are not detailed enough. Try tesselating the faces of one or both of your objects and do the boolean again. I had this same problem last week and that was the culprit. I tesselated my cutting object and bingo – no extra faces. Hope that helps. Dave Mennenoh
