Yes - and many will say NO WAY, as it can result in snapped drills for them. (And possibly not give a good plated slot). We don't support this (from inside the footprint), but what you need is a mechanical layer which defines the shape of the slot to be routed. You would need to talk to your prospective board vendor(s) to find out what would suit them best. It is unfortunate that this info can't be part of the foot-print. You will have to draw it on the board directly. A plated slots layer might be what is needed - although you may have to kludge what you need in PCB by calling the layer "route" or "outline", so PCB doesn't copy all pin / via pads onto that layer as well. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
