I don't remember. I looked at a whole lot of stuff when I was at the very start with FC. There is a lot of Tutorial Documentation out there and what with version changes and basic misconception on the part of the tutorial writers a lot of it is useless if not simply wrong! Perhaps one of the FC Gurus will take up the challenge of weeding the garden, so to speak!
Are you suggesting that FC Users should forget about 'Parts' altogether? Is there some function for which they are essential? Perhaps the next version should not have them at all!
Anyway, I can always prototype the hard way - printing and assembling physical parts.
