Subject: Re: [Homebrew_PCBs] Round to Square pcb

I tired to make it generic. Most software should
easily do what you want, just the terms may differ.
You might want to check with the user group for your
specific software. I know the concept works with Pads,
Pcad, Orcad PCB, and Protel. The polygon pour
functions are pretty much automatic... you set it up,
and let it route.

I personally avoid tweaks in the gerber file, as it
can be exceedingly error prone, and there is not an
easy way to do any type of DRC (design rule check)
from start to finish.

CadCam gerber editor may allow you to go in, and reset
the aperature lists.... you might be able to create a
macro to do some of the conversion automatically.
However CadCam editor was something like $US5000 and
its way overkill. I wonder if there is an open source
cadcam tool.

No problem with your English at all. I can understand
what you are trying to do, not proble
