This scene-based tutorial covers the basics of using SketchUp's Intersect with Model command. You use Intersect with Model to automatically generate edges wherever faces in your selected geometry intersect. Confused? It's really a lot simpler than it sounds.
To use this tutorial, just download the SketchUp 6 version of this model onto your computer, then open it in Google SketchUp 6. If you don't have SketchUp 6, you can download it for free at http://sketchup.google.com.
