I created a part for the PCI-E x1 board, but I can't seem to figure out how to make it so that once I add the part to my board, I can just extend the outline of the part with layer 20, dimension to fill in the top part of the board. I have attached an image of my part so you can see what I'm talking about.
Right now I have to try and overlay the board dimension outline right on top of the part outline. It would be nice if I could just continue off the part outline to finish up the board outline. Thanks.
