This thread is still saving the minds of new SketchUp users!
Thanks for the clear explanation and direction.

I am using SU for planning and modeling woodworking projects. I started with SU 2 weeks ago so I'm definitely at the Beginner level.
My first projects have been a workbench and a washer/dryer pedestal. The good news/bad news scenario is now that my wife has seen the SketchUp models she is coming up with all kinds of new projects for me!
