I just now finally (after about a week of frustrating work!) got a simple DC DC converter part with all of 4 pins successfully created and exported. Tomorrow I'm going to try once again to reduce the size of the schematic image and see if I can get the pins to line up correctly (I haven't been successful in the past, but then I couldn't get the part working without trying to reduce the size of the schematic either). It also looks at least for me, like parts editor is a one shot operation. Trying to re edit a part to fix problems tends to end up with the fonts reduced to close to nothing and unreadable or a fully red rectangle with nothing in it. As well sometimes after importing an svg from Inkscape and changing it in parts editor Inkscape won't render the modified svg. XML shows up in the XML editor but the screen is a white square with no image. Then I'll put the part up to see what I've done wrong :-).
