Another goal of the project is to generate 2D prints from 3D models. Any idea how hard is this going to be? Basically it needs to identify features (holes, edges, etc), then project these features to an orthographic plane, alone with associated dimensions.
are you familiar with Jan Sabinski's solid modelling in Haskell http://web.archive.org/web/20010605003250/http://www.numeric-quest.com/haske... he implements 3D projects onto 2D plane (although no feature selection etc) and is more a proof of principle. if you are interested in industrial strength solutions, I can recommend the openCascade (http://www.opencascade.org/) library. A Haskell binding would be very useful and something that I have thought about doing for some time, but alas had no time for. jvl
