Can anyone enlighten me as to the software used to design the layout for a diecut jigsaw puzzle? Or at least, how would you go about programming it? Simple designs would be easy, but with more complex pattern, the possibility for impossible pieces increases. How would the program achieve something like; http://www.oldpuzzles.com/ Plus an interesting article; http://www.oldpuzzles.com/styles/styles.htm The closest I could find is; http://www.drescherpuzzle.com/process.html but it's like they don't want to tell us something. Or is the diecut made by hand?
