Well, did you get it all figured out? I create parts similar to the core parts; make all the view files and the .fzp then zip them all up into the .fzpz and skip the parts editor all together. I guess you figured that out by now.
Have any luck with the spice thing and getting the resistance and tolerance to work?
I had Python on here all the time... don't know when I loaded on here. I loaded PiCharm Edu on here too as a coding refresher course... Maybe I will get back into it a little bit... Always wanted to learn Python...
