I've been playing with an idea for a few days now in my "spare time" and have run into some problems. The basic concept is to let users build "tracks" from a part library. This is quite simple to do when you have straights and 90 angles, but when I start throwing in curves that are say 45 deg rounded it becomes more difficult.
Has anyone worked on a project where you would snap parts together in an arbitrary fashion, and if so do you mind sharing some of your wisdom (or source code )?
