My designs are generally too dense to yield acceptable results with autorouting. See the photo diode receiver in the link above.

That is, 2 mil too late. The discrepancy grows as the clearance grows. With an 11 mil gap I had to ask for 14.1 mil minimum distance to receive DRC errors.

Oliver King-Smith wrote: > In Eagle, I could select an object by name, and then "move it" which would > automatically place it under my cursor. This is nice, as I don't have to go > hunting for the object I wish to move. Is there a way of doing this in PCB? Yes, sort of. There is "Select_by_name" somewhat hidden in the select menu. I tend to rip this sub menu off, so I have it ready when needed. The input understands regular expression matching. I find conatenating refdeses with "|" useful. Once the desired object is selected, you can do "Disperse_selected_elements" again from the select menu. This will align all selected objects at the top left of the canvas. They keep being selected. So you can drag them to some other place. This technique helps a lot with placement of larger designs. > I have attached an example.

Re: gEDA-user: Breaking up power planes
I've had good luck, for the size boards i've been doing, with imposing strict on-grid (0.005") disciple for drawing polygons. This alleviated what at first seemed to be inaccurate selection on the part of the tools (PCB) but was in fact inaccurate design. P.
