I'm working on a board in Eagle that need a oblong hole cut/routed through the PCB, but cant work out how to do it, any chance of some help?
Eagle really SUCKS for drawing tools. One of it's many (many many many) failings and shortcomings.
But in short, you can create arcs at each end of your hole - specifying start point, end point and (IIRC) arc radius. Then just manually type in coordinates for wires to connect them. As long as the start of your arc matches the start of your wire, they will be "connected" and move together.
The other option is to use a CAD program to create your outline and try to use one of the years-old user programs to import it into Eagle. Unfortunately I rarely have luck with this, as most of the import tools don't support splines or (sometimes) even arc segments, so they either import nothing or the straight lines only, which doesn't achieve what I want.
