I just want to recommend ProArchitect tutorials for C# beginners who is learning Rhinocommon basic.
I have just taken Rhino Developer C# Level 1 course and it is really, really great!
It is not free course, but the contents are superbly understandable.
The teacher guy’s philosophy truly opened my eyes.
Please do not get me wrong, I am not an advertising guy.
If you know any other tutorial or reference for learning Rhinocommon, please share it.
I really would like to know it.
