Re: gEDA-user: PCB+GL resistor p0rn
Hi, I compiled the latest version of FreeCAD and OpenCASCADE on my machine (with NVidia 8600 195.36.15, Debian 5.0.6). The compile worked reasonable and FreeCAD starts, but when I try to model something, e.g. cut a sphere out of a cube or chamfer and fillet the cube the screen-output is rubbish. Otherwise your general path appears reasonable to me. As it's only free as in beer, I don't fully suggest it, but gCAD3D seems to produce stable results - How about forging the script in a way to have the 3D-CAD program select the model it likes and really emit only XYRS, the footprint and ev. provide a table that correlates the footprint with a (choice of) 3D-model(s)? BTW. gCAD3D can read/write IGES, STEP and it's own documented ascii-format. Matthew Wilkins wrote: If it was me, I think I'd make a script for some 3D modelling package like FreeCAD to generate a 3D model using PCB's XY place file output. The process would be: 1. make FreeCAD 3D models for each of the components 2. generate an XY place file, board outline file and drill file in PCB 3. run a python script in FreeCAD that generates a model of the board based on the outline gerber file. Make holes using data from the drill file. 4. Run a script that makes an assembly by placing components based on the XY place file. At this point you should have a 3D model of the board, right in a 3D CAD program that can be used to model enclosures and other parts. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: current working file name in gschemrc
(Apologies for top-posting) Postscript is passed to the standard input of the print command, which is run using popen(). It uses the default shell 'sh' to run the command. I think that the sort of behaviour you're looking for might be best achieved by writing some sort of wrapper program that accepts Postscript on stdin and a destination filename as its argument.

Sounds like a very manual process, though. I have tried using Inkscape to panelize PCBs before in this manner and I found it tedious, and in particular you lose the ability to have the assembly drawing, drill files, etc. to be synchronized with the layout... at least the way I was doing it. I mean that if you modify the board layout in pcb at all, you'll have to re-export and re-modify the postscript output. Also, how would you make gerbers using this process?

Also, if you are editing the silkscreen layer in Inkscape, wouldn't it be hard to make sure you put the graphics/text/etc. in a place that doesn't conflict with elements on other layers?

gEDA-user: DRC check workaround for outline layer
This is probably not something we'd commit as is to PCB, as for some
cases, DRC warnings on the outline layer could be useful, but Bdale was
looking for something along these lines on IRC yesterday.
I'm not sure if I've caught all cases, but a simple test suggested it
might have the desired effect.
NB: You WONT get warnings if your outline touches / cuts off any parts!

gEDA-user: New autorouter high effort mode
Hi all, I've just pushed an update to my branch of PCB which provides a new autorouter high effort mode. What does it achieve? It wrings a few extra drops of goodness out of the autorouters. Typically it will route a few extra tracks. Useful if the autorouter is almost doing the job, but leaving a handful of tracks unrouted. Very useful if you're finishing work for the day and your computer has nothing better to do all night. How does it work? It's a brute force hack. It sits in an infinite loop repeatedly running the autorouters, but each run it slightly tweaks the cost function so that the routing ends up different. You can use it to burn CPU cycles to get slightly better autorouting. Quality ? No. It's a brute force hack. Make copies of your board before using the hack. If the hack produces useful results it's safe to take them back to a stable version of PCB. What's the work flow ? 0. Back up your PCB. WARNING: At the end of this work flow you will manually kill PCB (ctrl-C) without an opportunity to save. 1. Start PCB from a command shell, you'll need it to read status information 2. Set Settings - Autorouter high effort 3. Select at least one autorouter with Settings - Disable 2008 autorouter and Settings - Disable default autorouter 4. Start autorouting (from the Connects menu) 5. Wait for status messages in the shell. They look something like this: 2008FFF routed 208 nets and 332.681560. 2008AFF best yet with 208 nets and 329.589900. 2008BFF best yet with 208 nets and 328.583180. 2008CFF best yet with 208 nets and 328.471335. 2008DFF 208 nets and 328.515675. 2008EFF best yet with 208 nets and 328.347530. 2008GFF 207 nets and 330.267000. 2008HFF 207 nets and 337.805590. 2008IFF 206 nets and 327.564940. 2008JFF 206 nets and 328.720400. 2008KFF 207 nets and 328.265705. 2008EAF 207 nets and 325.139955. 2008EBF best yet with 209 nets and 326.294555. 2008ECF 208 nets and 329.716525. 2008EDF 207 nets and 327.660495.

This made it work better in many cases, but in some cases the older version works better. My branch of PCB includes both versions. I often try both autorouters and keep the best results.

gEDA-user: PCB+GL - Stable (eventually...)
Hi geda-users, Kai-Martin, Since I know some people have expressed an interest in why PCB+GL hasn't hit stable yet, I realised earlier that there was another step which is necessary... (besides cleaning up the hacks I made on top of the code I took from cairo). The polygon_speedup branch on which the GL code sits might seem unrelated, but in fact there are changes in that branch which are relied upon when rendering polygons. The polygon_speedup branch should mostly be a success, but I'm fairly sure it does increase CPU cycles for some operations. I've not had a chance to test it very scientifically, and I'm hesitant to push it to git HEAD without having at least made a few checks to see that it isn't penalising too many general cases. If necessary I could re-write the polygon rendering routines to NOT rely on the fact the polygon_speedup branch creates a spatial datastructure of all the contours within a polygon. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
