I'm on a Win 7 machine using Illustrator CC, using a mouse with the pen tool.
I created some shapes on one layer, and now want totrace just the outside of those shapes on a different layer. It worked well enough on the first two shapes I did this with (both comprised of ellipses layered to create a particular shape) but on this third one, it keeps bouncing me back to the original layer. This is the only shape that includes straight lines but I can't think of a reason that would keep me from being able to trace the outline of shapes on a different layer. Any idea of what I might be doing wrong?
