I am making a group of fine pitch parts with heat pads.
I see the check boxes in pad properties to automatically create "stop" and "cream" layers but the default exapansion values are not appropriate for these chips.
Can I change the expansion values when creating a library part?
Also, is there any way to change the mask expansion values on a board for a subset of parts?
Right now I'm creating the stop and cream layers with polygons but this is very slow.
