I stand corrected, as I've never had to do any "fancy" threads LoL. And I suppose with enough of a machine (which I don't have yet) it *shouldn't* bog it down. On the plus side about the whole HP thing, I am getting a new machine with a 6gb Quadro card, a newer I7 (think 3.09ghz one?), and hopefully upgrade to the 16gb ram currently running, ...sometime this week! Yay!
edit: sometimes I will download bolt models from McMaster to visually verify I have not screwed up a length or c'bore depth when mating several components, but afterward I would delete them from the file to make it easier to manipulate and reduce size/loading etc.
