Thanks for the prompt response. I consider you "one of the masters," judging from your excellent work for the 3DCC, etc. I am still baffled....How to do all this? Is there a good tutorial on this subject? One with pictures for illustrations, whatever? I've been frantically looking at some tutorials, and have been flabbergasted and frustrated by some. Unfortunately some folks might be great with a program, but they can't write for beans or spell. Some don't provide any pictures, etc. So I'm just about reduced to the point of blindly fiddling, and I haven't learned much that way.
