>>How do you mean load it into Imagine and trace the edges? Apparently this is something I have no yet come across. And as far as the fill to edge command, I haven't figured that SOB out yet!!<< Load it as a backdrop, add an axis, then use add lines to trace out the shape. You can try "convert image," which will sometimes, but not always work. Sometimes you can get a useful outline by using convert image and then choosing "no" when the requester asks if you want to add faces. Adding faces has almost always been a disaster for me, even when using fairly simple black and white images. I had trouble with fill to edge at first, too. I got some good advice about it, here, I think, and on IML. Though it was originally meant to help join different objects, it also makes short work of filling any irregular outline with faces. Just make sure that a) the set of edges you choose under "set edge" and "fill edge" are pretty much concave in shape (that is to say lines connecting the chosen points won't go outside the curve described by the edges), and b) make sure to pick one set of edges, hit "set edge," then deselect those edges, choose the second set, hit "fill edge." You should be there. One reason I'm going on and on about this, is that this feature (and smooth line, and the better fracture routine it allows) were the main reasons I upgraded to 3.2, and they've definitely been worth it all by themselves.

Micheal, Thanks for the advice on the Fill to Edge, I'll try it out. Sorry so long, been kind of hectic… Take it Easy, Doug
