How can I create a custom opening in the solder mask?

by DesignSpark

This tutorial requires:

DesignSpark PCB V11.0.0
DSPCB automatically adds openings in the solder mask for pads, however you may wish to add an opening for example under a power transistor tab to allow a copper area to act as a heatsink.
