Go on YOUTUBE and type in anything you want about Sketchup and you will get many videos showing you how to do something. You can definitley learn something form those videos.This program looks great so far but damn it is hard for me to pick up!
Any guidance other than the Google vids and trial and error?
Do the "Dummies" book. They have interactive examples online. It is an easy program for novices, but people with any other cad experience seem to have a steeper "relearning" curve. But it WILL come to you.
I have years of AutoCAD experience, but I've come to LOVE SU, and now use it much more than any other program.
