I second what others, such as Dick Mahany, have said about the video tutorials by Joe Zeh (a/k/a Chiefwoodworker). I struggled mightily with SketchUp, and had almost given up hope of doing any computer drawing. Chiefwoodworker saved the day. Joe's tutorials are extremely user-friendly, thorough, and easy-to-understand. I think for anyone who has had (or, is having) troubles with the SketchUp learning curve, the eight-part "beginners" series is a must. Joe has done us all a real service.
