I think I’m being dense. I’ve searched for an answer to this but I can’t find the answer or the question asked like this;
I’m trying to reveal parts of the copper on the edge of a board. This is with a view to soldering it directly to a screening can. I have already defined a copper pour for the entire board. What I want to do is selectively reveal areas. I’ve tried selecting the F.Mask layer, then Add Filled Zones, draw a rectangle and it doesn’t reveal anything.
this is the result - Nothing. Keepout is not useful because it only includes Tracks, Vias and Copper.
Any ideas? Is it possible? (I’m sure I used to do it in Eagle).
