    I am modeling antique furniture pieces from pictures found on the web and many of these old pieces have a lot of carving and appliques used to decorate them. What I've been doing is to trace the shapes as best as I can onto the pictures themselves, then lifting the line work off using copy and paste. I have resized the pictures to scale so the line drawings of the appliques are pretty accurate as to size. Anyway, I then use push/pull and scaling and such to add depth to the different areas and find some sort of texture that helps to make them a bit more obvious. It is working so so, and I would like to make them better.

    Anyone else doing anything like that who might be able to give me some pointers?
    Here's a skp of a door on a buffet I'm making. The carving is a handle to open the door with.

      Jerry, it would be helpful to have the original you're working from to see what it is supposed to look like.

            Thanks Marcus, I'll need to spend some time over there checking it out better, but it looked quite interesting.

              I think that thing in the middle of the scrollwork is more a medallion than a knob. I think you would normally use the key to pull the door open. We have buffet that, although there's no ornamentation on the door, it has no knobs or pulls.

              As to drawing the scrollwork, I think I would start drawing the perimeter and then use a method similar to the one that Marcus linked to. I would simplify it a great deal, though. By the time you get all the ornamentation drawn the model will be huge even by your standards. 😉 I expect the upper and lower scrollwork on that applique are the same just rotated 180° I would make a component of just one and use that.
