We have KeyCreator here at work. There is no easily accessible way to learn it. I have bought Dr Walts books and used the software's tutorials. Both have show-stopping mistakes.
Dr Walt spends a lot of time explaining how the software is different from earlier versions. This is like asking road directions and being told to turn where the buggy whip factory used to be. If I knew where the buggy whip factory used to be I would know the area and I wouldn't be asking directions! Then there are the mistakes. Trying to precisely follow along with the book ends up hitting multiple brick walls.
The Kubotek tutorials are not much better. Perhaps they are made for the initial numbered release, but when you get to the 3rd or 4th level of updates [e.g. 1.2.3 (4444)] the tutorial is broken.
I'd love for Kubotek to contact me here and win me back. But for now, no matter how good it may be, one of the 3D cad programs with a better industry support in training is a better way to go. I wold think they would realize people who don't learn the software are missed customers.
