| Subject: | [pcb-rnd] import .fp, modify and save as new footprint |
| replies: | 3254 from ge...@igor2.repo.hu |
I'm trying to import an .fp file from gedasymbols, modify it (by
removing a hole), and then save it as a footprint (to be an attribute
for a gschem symbol). I can break up the subc and remove the hole, but
then can't reconstitute the subc.
Here's what I've tried so far.
I start with erich_heinzle's footprint from gedasymbols:
http://www.gedasymbols.org/user/erich_heinzle/kicad/footprints/w_conn_misc.mod/arduino_header.fp
and rename to arduino_header_nohole.fp
=== Approach #1 ===
* Open footprint in pcb-rnd:
$ pcb-rnd arduino_header_nohole.fp
* Break up subcircuit
Select all visible: {s a a}
Break selection subcircuits to pieces {s b s}
* Remove the relevant hole (one of the 4 large mounting holes -- the one
at top-right)
Drag-select the hole
Right click on hole and select "Remove padstack"
Right click on silkscreen circle and select "Remove arc"
* Save layout {f s} (arduino_header_nohole.fp) and close pcb-rnd
* Try to open file in pcb-rnd:
$ pcb-rnd arduino_header_nohole.fp
This fails with message:
"none of the IO_ plugin recognized the file format of
arduino_header_nohole.fp - it's either not a valid board file or does
not match the format specified"
OK... maybe I need to convert the remaining pieces to a subcircuit
before saving?
=== Approach #2: convert all items to subc before saving ===
* Repeat the open/break/remove steps from Approach #1 above
* Convert items to subcircuit:
Select all visible {s a a}
Convert selection to subcircuit {s c s}
--- items disappear... ?
--- undo {u u} brings them back
=== Approach #3: convert original .fp to .lht first ===
* Open original arduino_header_nohole.fp footprint in pcb-rnd
* Convert to lht:
Save as {f a} and select lihata (lihata board v6).
Crash:
pcb-rnd(53855,0x7fff9ff923c0) malloc: *** error for object
0x21dffff9ccb4069: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Thanks,
James
PS: I'm using pcb-rnd 2.1.2 (non-svn) on mac osx
