I've just been learning Eagle. They have a great integration to Fusion 360 since it was purchased by Autodesk.
I've redone the GR78xx as my first test. Still learning a lot, but getting there.
Here's some renderings after I pushed it to Fusion...
I've still got some work to do, but this looks very promising. Most things seem to be rendering properly, though the solder mask isn't coming over and the fonts seem off a bit.
Once I have my boards in Eagle, I'll be able to drop the boards into my mechanical models. I'm very excited
PS My plan was to use only three pins to connect to the main PS board. Pins 1 & 5 are duplicates of 2 & 4.
