It's common to want to move PCB layouts into cad for chassis layout
work. What would be involved in giving PCB this feature?
Write an export HID. It's the same way we export gerber and
postscript.
.dxf would be very cool... but having been fooling with .dxf lately, i'd
hhmmm... QCAD only opens .dxf, pstoedit only opens PS, not EPS. But I
guess if I don't do 'fill page' I should be OK.

Oh, right. EPS, not PS output. Both are Postscript, and thus
rasterized, but the PS output may be scaled to fit
Hi,
thanks for your answer.

People,
I'm using the PCB package from the 20060907 gEDA disk release (thanks to
Stuart Brorson).
In the course of my current design effort, I elected to move some bypass
capacitors to the back side (solder) of the board. No problem so far.
When I routed the board I found that router was

Keep it vector, and either

The advantage of going pcb-dxf and not gerber-dxf is that you only
have to worry about supporting the data we have, which is
significantly simpler than trying to support a generic gerber file.

Lee's algorithm finds a set of (overlapping) paths between two points, which

I fully agree.
No autorouter can guess which cost factors are more important than others, and
human aid will often be necessary.
Some years ago I did a pcb with the autorouter of Eagle, and after finetuning

Oh yes, I hear that. What's easy and what's most generally useful
seldom overlap.

Yes, I will be checking in some fixes for guile-1.8.1 once I
