We use DP Technology Esprit (California) for NC turn, mill. It works well. It reads .mi files and generates the NC files. I think they have a folding module. Merry Mechanization (Florida) has a NC folding module. It used to be able to read MI files. Haven't used it for about 2 Revs, so I don't know if they still do or not. I did use it in the past for making flat patterns (on HPUX 8 and 9). I had problems with multiple users on a c-node system. It only worked on the host machine. Perhaps they have resolved that. Very few users of c-nodes anymore anyway. I didn't use the NC portion of the program. Lynn
