Parametrically modeling folded paper is hard. The problem is physics -- paper has actual dimensions and folds in it constrain the spatial configurations it can achieve. These real-world constraints inevitably imply that any model will require the solution of simultaneous equations, which propagation-based systems cannot do. (The Goal Seeker pattern demonstrates a partial solution to this problem.) That said, approximations can be useful in design and this sample shows a way to simulate a folded paper system, ceding from reality some dimensional variation in the individual panels.      ... more on Design Patterns CA
