One of the major barriers to getting going with Archicad has been realizing that it's going to be a year long learning process until I'll be at the level that I'd like. Ever since using my parents clone Mac as a kid with Adobe Pagemaker, I've just been able to teach myself design programs pretty quickly. With the complexity of the BIM and CAD programs. I'm organizing my notes to create a guidebook for myself to document everything I'm learning.
