Hi Tom, thanks for responding (and so quickly!)
I'm attaching an example of what I'm talking about--I'm just trying to figure out the technique, because the hard drive on my laptop crashed last night and I want to recreate some of the designs I had there while I can remember them, but I don't want to take as long as I did the first time....
At any rate, you'll see it's just a basic edge-joined table top, and I put a line on the right edge to indicate the basic kind of detail I'm talking about. I'm thinking that my problem has to do with not knowing the proper configuration of components/groups etc. to get this to work. I've tried drawing a line like you said, but there's always some sort of problem: I can't select the full line, or I can't select the chamfer with followme, etc.
Sorry to be asking such tedious questions...
*EDIT: Holy crap, guess I posted a minute too late--that's incredibly awesome mon frere, and merci beaucoup
