Hi Brian,

>>>just how did you do that in such a short time

I just created as already mentioned, which was, I loaded the picture of the frame, then I followed (traced) the path of the frame (piping) using the "free form~ through points" and placed a point at each intersection (where the pipes cross over) I did that first for the first path:-



I then added any needed points to correct the shape (keeping points to a minimal), then I selected all the points where the pipe moved behind (at the intersections) and moved them using align.
I then repeated for the other 3 paths.
