Hi everyone,

I created a script to help me make a 3D model of a populated PCB. I thought
I would share in case someone else has a need for this.  I am using a
combination of Gschem, PCB, OpenSCAD, and my custom perl script.  The
script just acts like a virtual pick and place machine.

Below is a link to the example project that I created. (The compressed file
at the bottom of the page has the schematic, PCB, OpenSCAD models, and Perl
script in it.  The PCB and models all use mm as the units.)
To run the script pcbto3d.pl in the project directory.
It will create a file called "balance_sensors.scad"  that you can open and
rotate around in OpenSCAD.

Details about how it works...
1. I added the 3D models to the schematic symbols then use one of the BOM
backends to export the redefs and 3D model relationship.  (Note the PCB
footprints and 3D models need to have the same origin point.)
2. Export xy file to be able to find where all the 3D models location and
rotation.
3. Export the gerber data to get the plated drill hole locations so I could
show all the mounting holes and vias.
4. Read the work are size from the PCB file. (Note the script does not use
the outline layer.)
5. Create the OpenSCAD file of the assembled PCB.

Enjoy,
Matthew
