drmdzh Posted August 24, 2007 Share Posted August 24, 2007 Why can't I subtract these solids? Quote Link to comment
Ray Libby Posted August 24, 2007 Share Posted August 24, 2007 Because they are groups. Quote Link to comment
Guest Posted August 24, 2007 Share Posted August 24, 2007 You have groups of nurbs surfaces. To use subtract solids, you need solid entities. Quote Link to comment
Ray Libby Posted August 24, 2007 Share Posted August 24, 2007 Here you go. I recreated the wall as an extrude then selected the parts to subtract and did add solids, then subtrated that from the wall. Quote Link to comment
drmdzh Posted August 24, 2007 Author Share Posted August 24, 2007 So how would I go about making them solids? I used extrude to form the wall. Then I tried doing the "Extract Curve" - Extrude along path thing, just like in the tutorial to create the top of the wall. I turned the extrude into a nurbs curve while I was doing that I think, nothing I tried could make it work. I managed to extract the curve, but couldn't extrude along it. So I traced the top line of the wall and extruded along that. I have read the entire book, worked my way through the tutorials, some of which don't even work (see my other post) and still find that almost everything I try to do doesn't work. I have never been as frustrated and angry with something as much as this. It is driving me crazy and the book really doesn't explain things, like the answer you just gave me. It WAS a solid, I converted it to try to do something else, can I convert it back? Quote Link to comment
drmdzh Posted August 24, 2007 Author Share Posted August 24, 2007 I really appreciate it. So did you use the top of the wall I created, and just re-made the bottom part by doing an extrude? Then subtracted from that? Quote Link to comment
Ray Libby Posted August 24, 2007 Share Posted August 24, 2007 I left the cap and recreated just the wall, then subtracted from that. Quote Link to comment
