Yeah ill have a look around see if i can get a copy. I know it seems silly and a big cost tbh we mainly got it because the m.d is planning on moving onto tool design, but we also have a company that we work close to which uses it, so they can send us designs over and we can do what we need to do with them, it also means if or when our m.d is teaching himself he can call up and ask how somethings done so easier reference, and we can also transfer tooling paths onto our 3axis CNC mills (hurco) to do all the 3d tooling to either the main job or electrodes for spark eroding. But most our jobs are done on a favour basis for this other company, if they do one then we'd have to out source or make multiple electrodes to do what could normally be done using a CAD program, which is why i plan on getting involved
