PhiiLL Posted April 24, 2017 Share Posted April 24, 2017 Hey guys, I want to make a simple screw in Houdini, but the boolean operator is not very helpful when I try to make the thread out of a helix :/ The aim is to subtract the helix from the body of my screw, which should create my thread. But it won't subtract it entirely :/ Could you help me please? screw.hipnc Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted April 24, 2017 Share Posted April 24, 2017 I did the cap after the convert to polygon plus a fuse. It works after that. screw_fixed.hipnc 1 Quote Link to comment Share on other sites More sharing options...

Maybe I can avoid similar problems in the future if I understand what the problem was Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted April 26, 2017 Share Posted April 26, 2017 The NURB cap wasn't lining up with the rest of the tube. NURBS are good for some stuff and not for others. The polygon cap matched the rest of the geometry perfectly. 1 Quote Link to comment Share on other sites More sharing options...
