I've been trying to locate some information on how to create the segmented paste mask openings in a SM part that requires a central thermal pad. I looking at some of the conversation, I see that some people use copper. How do you accurately create a rectangle to the size and shape that you want?...and then how to you accurately place that rectangle at the origin so that you could do a step and repeat process?
So far, I've simply been placing thru hole pads and adding the paste layer that I want for each one, thereby creating a grid.
Also, since this drafting tool is so challenging, can I create shapes in AutoCad and dxf into Pads Layout?
