Rounded EAGLE Routing?

Trying to spread traces around, I wondered how the rounded wire bend routing options worked in CadSoft EAGLE. There's a free-form, spline sort of wire bend option, and I went around to all the traces on the latest minimalduino version (which needs a better name btw), widening and pushing and pulling traces to try to fill empty areas. Sort of looks hand-drawn, kind of hippyish. I was hoping to find a way to eliminate one of the jumper wires, but no luck. I introduced an air-wire, actually, but can fix that with a little nudging.

Not sure whether to get a few of the rounded or "normal" versions when the DorkbotPDX PCB order is due. I got the idea trying to arrange the traces in the lower left and upper middle areas, after working in some patterning in the diagonals. Your opinions are most welcome!

Update 5/21/10: The mail to Laen at DorkbotPDX never sent?! Went to mail him asking him if they worked out, and the mail was in "Drafts". Stayed up late Sunday night tweaking them and... crap! Guess I'll have to wait for the next order; had a 3-digit 7-segment display board too, based on an SAA1064..:(


  1. I think the curvy might be interesting. As far as the rectangular goes, I find the .16 traces very hard to iron on at home. I would personally change them to .24 or .32 traces.

    Final Vote: Do 1 dorkbot batch curvy. Keep the rectangular for home etching. (with thicker traces)

  2. Thanks, I tweaked the curvy one and submitted it to the Dorkbot PCB order, but it had some DRC issues so I'm not sure if it will work. I'll keep working on a fatter trace board though.

  3. Sweet PCB, I was never really aware of the rounded routing modes! I've been working on similar things lately, using the topological autorouter TopoR. It often does a decent autorouting job, but of course, polishing existing routings or fully manual routing is also possible. Got a basic converter running to get the results back to Eagle, if you want a copy, drop me a line! (info@).
