I have not found any software that uses the same post processor or the same methods. The best way to learn is to work with a known good post, modify it, save it as a different name like 'test1', and work from there. CAMWorks has some files for working with the posts but is is fairly vague. Also, if you download the UPG from CAMWorks you can use that as a template however, there are some features that one cannot change or access from that. I mainly use the UPG for compiling.
