Am trying to make a footprint for this Osram TopLED.
The pads are enormous - for heatsinking reasons I guess - but the exposed area for the pads should be much smaller than the pads and in the corners of said pads.
I assume one needs to untick the solder mask box on the pad and then draw a filled polygon on the soldermask layer. However, although it’s obvious how to draw lines, I just can’t see a way how to draw a filled rectangle. How does one go about doing that please?
