New boolean function ...

[Stiglr]

I don't think the improvements will show so much if you just cut a square hole out of a flat object.

Try something like a section of a globe cut out of a cube, or cut an object out of a complex 3D shape; then you'll see the gains made.

Even with that first example, all it would take to improve that is to Combine a few of the polygons and that's all the cleanup you'd likely need. Before, you might have dozens of vertices hanging around an area where they all ought to be welded together as one.

I think the new Boolean is a HUGE improvement over earlier versions. In its effect as well as in making the setup sequence more intuitive. Hats off, Andy and crew!
