I have a circular PCB and would like to do a ground pour on the entire thing. I’m thinking I could just draw a rectangle enclosing the circle, and that the fab house would just cut it off. That seems like more of a hack though. I’ve also been experimenting with all of the wire routing options in the polygon mode. That seems to only get me a quarter-circle at a time at best and my skills are not always good enough to match up the final quarter circle when I come around.
Does anyone know how to do a circular ground pour for your PCB in Eagle?
Magic incantation for the CLI window, to draw a circular polygon (using the current layer and line width, centered on the “mark”, with radius 10 in current grid units):
poly gnd (P 10 0) +180 (P 10 180) +180 (P 10 0);
That translates approximately to “draw a 180 degree arc for the first half of the circle (from 0 to 180 degrees), and then another 180 degree arc from there back to the beginning of the circle.”
(every time I hear people say how clunky EAGLE’s odd GUI/CLI combo interface is, I remember how it can do things like this, too…)
westfw, that was awesome! Thank you so much both. Yes, EAGLE does offer a lot of great features and I’m happy there’s a lot of smart people on this forum who collectively know many of them. I wonder if some kind of photoshop online video course might be worthwhile? I’d certainly be happy watching a little series on lynda.com about using more of EAGLE’s command line interface and writing my own ULPs.
