Kenat ranted: "Sure you don't know how to use descriptive geometry..."
Well, no, but it can sure help. I can lay out a complex pipe joint and get the ellipse dimensions, or a paper pattern for the shop, more quickly using descriptive geometry and 2D cad than firing up the pathetically slow seat of Inventor I have...
And a freshie the boss hired for the "other side" of my company was having fits the other day, trying to get a view that would show a particular detail (aka auxilliary projection). I had to show him how he could define the rotation plane for the view...using 2D sketch techniques...he thought I was some kinda wizard.
Style. Nice word. Clean, well-laid out drawings are a good goal, and I try to aspire to them. It helps to do so, if you are a self-checking engineer like most of us have to be these days. Keeping the print readable helps you when you are double-checking to see if you missed any dimensions, datum descriptors, tolerances... Someday, when I'm done here, I may have to post a print that another engineer developed and I inherited. Dimensions in alternating font sizes, overlapping in places, leaders and dimensions lines pointing to ambiguous areas of the part, no detail views, all crammed into a single A-size sheet. The part caused our shop trouble for years, until I managed to spot the tolerance stack that made it operate improperly in some combinations...but that didn't happen until I redrew the whole thing.
