The test isn't really equivalent to IsPointInBox, it does computation with real polygons - its not just looking at the bounding box. I forgot to mention, that I did cut out the "rectangle polys only" tests in GatherSubnets. OTOH, I've not tested the auto-router - I don't generally use it. From the comments in the code (which I gather you wrote), I thought it implied that the rectangle poly requirement was due to the via-rats code using IsPointInBox. If there is some limitation in the auto-router's understanding of Polygons which means they are treated as boxes, then perhaps I need to take another look. (Any ideas where to start prodding, or how to test that?)
