P*otel help

Use Via instead of pad :)
 

Re: Protel help

Protel doesn't do central cutouts yet. The only way to get the representation you want is by using a pad for the hole.

A polygon to the edge is done by using a keepout boundary, then copper flooding. The flood will stop at the keepout (you can make the keepout boundary as narrow as you need to make the proper shape and limit).
