Is there a way to create an obstruct that only affects the solder mask? I would like to create an area of exposed copper that a heat sink can be attached to.
Thanks for any help.
Are you using PADS or Xpedition? I can move your question to the appropriate sub-group if you're still looking for an answer.
Draw a Filled shape on the SolderMask layer where you want exposed copper.
I'm pretty sure that anything you draw on the solder mask layers will appear in the output data.
Have you tried drawing something and then creating Gerber data?
