Yeah, that'll be the same thing!

Yeah. I'm fortunate that I get to do a lot of different stuff! Originally I just did our pcb software but I also done a lot of embedded stuff for quite a few years now.

Ouch! It's a pretty trivial exercise when you figure out how to do it. Took me about a day I think to get the software producing the isolation traces. Our software outputs direct to NC and doesn't require external software to import gerber.
