[Kicad-developers] Length matching/tuning V2.
Hi, I worked a few month ago on a feature concerning trace length tunning.See This branch[1] , this bug repport[2], this youtube video[3]. Several people have been contacting me to tell me that it is very useful and I should keep working on it, so that it can be integrated in mainline. So I'm going to spend a few days on it. I will correct bugs, make code cleaner. But one of the thing I think should be done is port this to openGL mode. The thing is I don't know at all how it works. Here is what I need to do: *Do something when the mouse is clicked and my toolkit is selected. *Do something when the mouse moves and my toolkit is selected. *Draw temporary lines of given width on the screen. *Redraw everything, but only the real things (traces, pads ect), not temporary lines. *Prompt a window in order to have the user input a value. Do you have advices/hints on how to do that? (so that I don't loose too much time searching). Do you see any other thing I should do so that it can be integrated in product branch? Also I think CERN said they would work on length matching. Could you tell me more so that we don't work on 2 concurrent solutions? Thank's in advance. Pierre.

Re: [Kicad-developers] Trapezoidal pads and planes.
Nick, I have used trapezoidal pads to connect between PCB antennas and traces. There are precise rules on trace thickness for antennas, and this let me have one thing I could modify in the footprint to handle multiple different feedline widths.

From an user perspective if xyz pad shape is supported, it should be supported without artificial limitations. No tool designer may know how an innovative user uses pad shapes. The fact that a trapezoidal pad is usable to decrease reflections near package should not limit it's usefulness for optimisation of, say wave soldering. If such shape is used for gradual impedance scaling, the fill keepout must follow anyway or be far enough not to matter regarding the transmission line properties. Just the fact that current state leaves pads unconnected is enough to mark behavior as a bug. Pad left unconnected from the assigned net is a serious no-no.

[Kicad-developers] OSX: Configurable OS X target version for building KiCad
Hi all, the attached bzr-bundle/patch (against 5302) removes the hard-coded “-mmacosx-min-version=10.5” parameters for KiCad, internal boost, and wxWidgets build script. Instead, it is now required to specify the target version using the existing CMake parameter -DCMAKE_OSX_DEPLOYMENT_TARGET=10.x” during KiCad configuration (or, wxWidgets build script). It was done on purpose to force an explicit specification of the target version, because if nothing is specified various packages seem to set different defaults, which might cause problems. Compiling documentation has been adapted accordingly. Note: Setting -DCMAKE_OSX_DEPLOYMENT_TARGET=10.7” (instead of default 10.5 that was hardcoded before) seems to fix the red-blob problem with eeschema on recent OS X versions.

Trapezoid pads can be useful for control distribution of melting solder paste. For each pad, you can set its connection to the copper zone to None and still it will be microwave compatible. This is sort of what I was using the trapezoidal pads for. Someone created them in the Resistors_Universal library. It appears they were designed to handle multiple SMD resistor sizes. I only use them when prototyping since most of my in house passive components are 0805 and 1206 sizes so it's handy to have these footprints rather than using an oversized rectangular pad which can make soldering more difficult. I was trying to save etching away large amounts of copper by using a ground plane instead of traces. This is the first time I tried this so I was caught off guard by the fact the the zone did not connect to the pads. I checked the zone documentation in Pcbnew and I didn't see anything about trapezoidal pads not connecting. It's not a big deal but we should document the fact that trapezoidal pads are not connected to zone fills. Although, it would be useful to allow trapezoidal pads to connect to zones as long as the can be excluded for microwave purposes.

[Kicad-developers] [MERGE] kicad3dmodels
I have no idea who launchpad notifies of merge requests, so for the
benefit of everyone else on this list I am reproducing my merge
request from my kicad branch lp:~cirilo-bernardo/kicad/vrml_tools
https://code.launchpad.net/~cirilo-bernardo/kicad/vrml_tools
=
These changes merge the Kicad3DModels VRML parametric modeling project to
provide users with python scriptable tools for creating 3D models. The
code has been cleaned up so that the public members comply with the KiCad
coding style.
To build, pass CMake the flag -DKICAD_SCRIPTING_VRML=ON
So far this has only been tested on Linux; I would appreciate any help
in testing (and fixing) on OSX and Windows.
Example use, assuming a local installation in ${HOME}/usr/local
export PATH=${HOME}/usr/local/bin:${PATH}
export LD_LIBRARY_PATH=${HOME}/usr/local/lib/kicad/kc3d
export PYTHONPATH=${LD_LIBRARY_PATH}
export KC3DDIR=${HOME}/usr/local/shared/kicad/kc3d/appearances
(required for binary execs to find material appearances)
(now to set execution on some shell scripts)
cd ${HOME}/usr/local/shared/kicad/kc3d/scripts
find . -name *.sh | xargs chmod u+x
cd mkdir test_vrml cd test_vrml
${HOME}/usr/local/shared/kicad/kc3d/scripts/batch/conn/generate.sh
${HOME}/usr/local/shared/kicad/kc3d/scripts/batch/diode/generate.sh
${HOME}/usr/local/shared/kicad/kc3d/scripts/batch/dipn/generate.sh
${HOME}/usr/local/shared/kicad/kc3d/scripts/batch/resistor/generate.sh
Some of those bash scripts make use of parameter-driven binary
executables and others invoke python scripts. At the end 6583
models are generated in about 40s and with a total disk usage
of 1.7GB. The source code itself is about 12KSLOC at 1.3MB.
The huge number of models generated in a short time demonstrates
the power of parametric modeling.
