gEDA-user: Polygons in footprints
How hard would it be to get PCB to accept polygons in footprints? We'd need polygons on both copper and silk layers, and both with and without soldermask. Phil ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Can you clarify your needs a little bit more? -dave Phil ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

It is pretty weak at 3D. It does have Z information, and would probably work well enough for getting component volumes. PCB is not going to be able to do anything with a component volume, though. There is another open ASCII format designed for MCAD/ECAD integration: IDF. I use it everyday at work to exchange data between the mechanical CAD and the electronic CAD programs (in both directions). I don't know anything about IDF, and don't have time to study something I don't have an immediate use for. My background is electronics design and design automation, so all the mechanical CAD packages are new territory for me -- I'm not exactly your first choice for mechanical CAD work. Let me be clear about my motivation: I wrote a 2D DXF processor for another project, so I have become familiar with a particular DXF library that is very robust for 2D information. Importing board outlines and mounting hole placement seems like useful functionality, and is a limited goal that I could probably accomplish. If other people would find that functionality useful, I will look into it. If it is not useful enough in that form to interest other users, I won't bother. And while I'm stating my limitations, I don't understand DXF well enough to use this library to *export* DXF from pcb -- that is a different, much harder, problem. I can see where it would be very nice to export a mechanical drawing of a pcb with component placement in a form that could be imported into a mechanical package, but I think the project is beyond my knowledge of DXF. -dave ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

[jg]The makefile tells you each time in a way that you can copy and paste it to execute it. The makefile spits out versions for bash, csh, etc. The makefile from gEDA/gaf out of CVS does that, but I don't believe the regular old source tarball for gschem does that. Yep. Gentoo uses /etc/ld.so.conf, but I got it taken care of by uninstalling the original version, installing the code from CVS locally, and then exporting a few things in my .bashrc file.

You may import drawings from DXF, but what about component positions, for example? will you able to get a 3D model of your PCB board? There is another open ASCII format designed for MCAD/ECAD integration: IDF. I use it everyday at work to exchange data between the mechanical CAD and the electronic CAD programs (in both directions). Here is an article about it: http://electronics-cooling.com/articles/2002/2002_november_a2.php I remember I got the specs from a company called Intermedius Design Integration, but I am unable to find the link right now. The specs are also available at: www.aertia.com/docs/priware/IDF_V20_Spec.pdf www.aertia.com/docs/priware/IDF_V30_Spec.pdf The mechanical CAD programs I have seen support versions 2.0 and 3.0 (they are quite similar). There is a 4.0 version released, but the format changes a lot, and I haven't seen any program supporting it.

gEDA-user: Vendor map
When applying the vendor drill map, is it possible to change pad size to meet DRC as specified in the drillmap file. Some of the new drill sizes make my DRC fail due to copper annulus being to small. -Lares pgpNzW2m4IyY8.pgp Description: PGP signature ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
