Since there is no CAD newsgroup (the LSI cad group is not for mechanical type CAD) I am posting here to ask for help. Does anyone have a simple way to convert a complex 2D outline into a 3D surface (faces or mesh)? Basically I need something that works like EDGESURF but with more complex shapes (edgesurf only works with 4 sided shapes). What I have is a 2D logo I drew from lines and polylines to form an outline. The logo basically spells the word DISK in fancy outline letters. I need to fill in the letter shapes to make them a solid (I don't want to use hatch, it only consists of lines). for example suppose I have this shape: ________ |_______ \ _ | | | | | | | |_____| | |________ / I want to make it a solid 3D face or mesh like this: ________ |_|_|_|_|_\ _ |__| |_| |__| |_|_____|__| |_|_|_|_|_/ Then I will take the logo and translate it into a DXF file that can be converted and read by the DKBtrace raytracer program. There I will render it as a metallic logo. Without converting the logo to 3D faces or a poly mesh, the raytracer bombs out, thinking that its just a wireframe and the lines have no thickness. My only other alternative right now is to go in by hand and divide the logo into smaller and simpler 4 sided shapes and use EDGESURF to make each little part into a separate mesh. This will be really tedious and I am hoping someone out there knows a way around it. Email me. [btw: I did RTFM already. from what I read autocad doesn't support what I want to do directly. I am hoping someone knows a trick, or has a autolisp routine that will do what I want] -- John Sparks |D.I.S.K.
