Ascii file to import ground via 'parts' into a pcb file.

[eas-man]

I was wondering if someone could tell me how to write a small ascii file that will load ground via 'parts' connected to net gnd. I suppose 1000 vias would suffice for this design. Thanks!

Can you explain what your tying to do, I cant quite make it out?

Sure .... I want to use a part, which is just a drilled pad, as a ground via, instead of a normal via. I used to have a simple netlist file that I could edit and import into a design. This netlist file contained the correct terminology to identify the ground 'part' in the library, and also connected the 'parts' to a net.
I use these ground parts mainly in RF designs because they don't get blown away as easily as the vias do (like during moves and edits), and of course they don't have to be connected to a trace, but merely plopped onto copper as needed.

Add via option works fine for what you want to achieve.

Add the following line in Powerpcb.ini and via's will not be deleted.

\Padspwr\Powerpcb\Powerpcb.ini

Under [ECO Preferences]

KeepStitchingVias=1

Good luck
