Re: [PEDA] Arc's in the keepout
The only other thing I tried to do was put a square keepout around the board and try to place a polygon plane on the outside of the board. I couldn't get it to work right. This is not a round board, it has three arcs both + and -, and I chose to use Arc Any Angle. I do not know if this has a different effect then using place an arc.

Re: [PEDA] Arc's in the keepout
No, you did the right thing. For Autorouting, you can use arcs, but they must somehow be contained within an enclosed polygon shape keepout with no arcs. You have to enclose corner arcs with a 90 degree corner etc. To make a circular board you would create the keepout circle(arc) and then surround it with a rectangle so it will work. The router will stay within the circle, but requires the rectangle to initialize. Then... remove the 'workaround' tracks when you are done if you do not want them. -- Colby Siemer** Custom Battery Chargers ** Custom Power Supplies PowerStream Technology ** Custom UPS 140 S.

I've been told that early versions of Autocad couldn't draw true circles -- it drew 32 sided polygons instead -- but most people never noticed that the circles weren't true circles. Ik think it is also possible to photoplot the arc to a gerber file and use the option 'Use software arcs'. This option could be found in the 'advanced tab' of the Gerber setup. The arc will be replaced by short straight line segments. The gerber file could be imported back into the pcb. This is not my own idea, in the past it was mentioned by someone on the forum. Let's do it together, the forum is great!
