Removing a pad's  cutout

Normally a pad generates its own solder mask cutout. However you may want to define a custom no solder mask area and do not want the pad to automatically create a no solder mask region. You do this by selecting the pad and unchecking the Add Solder Cutouts checkbox in the pads properties panel.

Adding a custom soldermask cutout

You can add a custom solder mask cutout to the top or bottom side of the PCB. To add one you must have either the top copper layer or the bottom copper layer selected. You can do this using the layers panel.

A custom solder mask cutout can be rectangular (with optional rounded corners) or circular/elliptical or polygonal/curved.
