I suppose the best way would be to build the shape in illustrator and use clean pathfinder operations, so you end up with one contiguous path to use. Otehr than that you could try to use shape layer merges and copy&paste the mask in a shape path...
Building your shape in Illustrator would be my first choice. Shape layer merges would be my second choice. It depends entirely on the complexity of the shape. A screenshot would help...
I'd like to extrude these shapes.
Now I know these are made from solids, but the original is an ellipse mask with some other masks drawn over it.
I was able to make these same half rings with a shape layer and some masks. I'd ultimately like to make that shape a shape layer of its own with no masks so that I can extrude it in 3D.
I wish there was some sort of magic wand tool that would let me select the shape, save the selection as a path, then use that... man I really have to go into a whole nother program to do this? Geeze.
Pre-compose, use Layer--> Autotrace on the ppre-comp, then copy&paste the resulting masks into shape layer paths.
Ah never got to thank you guys for your help! That ended up working and doing just what I wanted... Only thing that was still messing up was the ancher point. But no problem now.
Thanks again guys!
