Probably a dumb queston....but...any way that Google's free Sketchup program will do simple resizing of ribs? I envision putting in tables of particular rib; having Sketchup draw the ribs, and then do all of the resizing as shown in the very first set of drawings on this thread. I do not know Sketchup, but see that it has some very powerful functions that might work for a simple guy like me. thanks Rich
