I have been building models for a quite a while. I have recently bought a copy of Rhino 4.0 and decided I would try to learn how to design them. I have successfully created some little models but there are two things that am just not understanding. 1) Not all modeling solutions produce surfaces that are developable. Is there a secret to setting out to create a model that will have developable surfaces? Or is the old "Smash" function the way to go? 2) I have figured out how to put complex textures (like the markings, paint, and panel lines of an aircraft fuselage) on a model but when I unroll (smash) it the ENTIRE texture is inserted on each individual part. Can anyone provide some advice on this? Thanks for your help.
