I work in the automotive industry, and design engineering products using Catiav5 solid modeling. I want to increase my understanding and experience with surfacing concepts, and I believe the knowledge Nikita is willing to share in his tutorials will do the trick! I'm going to start with the watch tutorials, and I already bought the beginner pack that I'll move to after that. Thanks, Nikita, for taking the time to share your knowledge. It is so hard to learn without someone like you doing so.
