--0000000000009be043059c0aa7b9 Content-Type: text/plain; charset="UTF-8" Hi Richard- What's wrong with wide traces? The end caps? What about using a large element pad for your connections instead of a polygon? I'll have to look and see if there any facility for polygon-polygon clearance. I've only delved into polygons a couple times, but I have a vague recollection of something.
