Thanks Joe - I've often tried to make tubes and handles in Bryce and have always used symetrical lattices, which sort of works, but the results are never really round like using the method you explained. And as for the cloud tutorial, I knew about most of it, but not the part about having all the options checked in that  drop down menu in the mat lab. I'll have to experiment with both methods you described and see what I can come up with. Again.....thanks, they are much appreciated!
