for the first part you shouldn't have any problem creating the 7 rectangular pins, for the large one in the middle add a terminal, draw copper in the shape you need, then associate it to the terminal
do the same for the last one, add two terminals, draw the 2 pieces of copper, associate each piece to a terminal
the last piece of the puzzle is when you output Gerber make sure Pins With Associated Copper is set correctly in CAM setup - Layers
out of the box, the default should be already set correctly, but I don't know what else you may have going on so play with each of the selections there to see the difference using preview
Hi markl, thanks for the quick reply. I think I was on the right track, trying to use the Copper option. I'll try what you suggest later and see how I get on.
Okay, so I've nailed this now (and of course it was much easier than I thought!). Thanks to markl for his help.
