Well, as a sort of prelude to some sort of SketchUp "bootcamp" which still needs to be figured out, let's have a little exercise. Everyone down on the floor and give 10 push pulls!
Alright, so for our first exercise I've chosen Doug Stowe's little Friendship Box. I've given you all the dimensions you need to draw it. And lest someone should say there's missing dimensions, you're woodworkers. Figure it out. do what makes sense. Where's that master sergeant smilie?
You get 10 minutes. Be honest.
Remember to save the SketchUp file. You're gonna need it again.
