diff for gEDA PCB export in fped
I have 1) sorted out the tabbing 2) simplified > 1 element export by exporting elements in a layout (.pcb) 3) documented incompatibilities in the README 4) done it as a diff against origin master let me know if you need anything else done Cheers. Erich From dae69d9a63071a15c213c72e70b86fe963a67dd4 Mon Sep 17 00:00:00 2001 From: erich_heinzle <a1039181@gmail.com> Date: Sun, 22 Jan 2017 23:48:57 +1030 Subject: [PATCH] support for export to gEDA format of single and multiple footprints in a .pcb layout

process and verificative measurements helps efficient and accurate

review.
|
||||
|
||||
Leveraging the work already done, and growing the intellectual commons
|
||||
of available footprints has motivated the addition of an export to gEDA
|
||||
pcb format option. Single or multiple footprints are exported in a
|
||||
gEDA PCB layout (.pcb) file. A select all command can be used, followed
|
||||
by a "disperse elements" command, to allow viewing of multiple elements
|
||||
in the gEDA layout editor. An element can then be selected, cut to
|
||||
buffer, and exported to a footprint (.fp) file with the usual menu
|
||||
commands.
|
||||
|
||||
gEDA PCB format footprints are exported in centimil units. Pads with
|
||||
offset centre holes are not faithfully reproduced; the pad is exported
|
||||
with minimum dimensions and centred on the hole. Trapezoidal and
|
||||
roundrect pads are not supported in gEDA.
