Kurt Magness Posted May 14, 2002 Share Posted May 14, 2002 Does anybody know how to do this? I am trying to make tree trunks or slightly curved or bowed tapered extrudes for sailboat masts. Also how would you warp a 3d ploygon to look like a sail? Kurt Quote Link to comment
Marc Posted May 14, 2002 Share Posted May 14, 2002 Try lofting. And... Create nurbs surface and then manipulate the U and V degrees in the oip. Quote Link to comment
Matthew Giampapa Posted May 14, 2002 Share Posted May 14, 2002 I know nothing about sails, but I wanted to try this and it's a good opportunity to post a picture. Draw your mast (I lofted two circles together) then draw a polygon in the shape of the sail, extrude it 0 depth and use the convert to nurbs command to turn it into a nurbs surface. Now change the number of vertices for U and V, then pull one of them out to put a little curve in the surface.

QB] You don't have to extrude the shape, just use the "Create Surface From Curves" command. It will convert any 2-D object into a nurbs surface. Quote Link to comment
Kurt Magness Posted May 15, 2002 Author Share Posted May 15, 2002 I am unfamilar with the term "lofting" and I can not find it referenced in the manual. The mast should be tapered and curved slightly towards the top 1/3 of the mast. Tapered extrude along a path? Quote Link to comment
Vectorworks, Inc Employee Biplab Posted May 15, 2002 Vectorworks, Inc Employee Share Posted May 15, 2002 Lofting is the process - where you draw 2 or more cross-sections of the final shape you want and then use this tool to create a skinned surface. I believe there are examples and tutorials in the 3DPowerPack manual. Quote Link to comment
