Daryl:

I thought it came from the "hand drafting" days before CAD when lazy
engineers/draftsmen just changed the number in the dimension string and
didn't redraw the plan/element to scale!

Paper stretching is the least problem.  I've seen draftmen who can draw a 
straight line freehand draft drawings with just a sharp pencil (no scale, no

triangles, no t-square, etc.) that looked like they were perfectly drawn to 
scale with such equipment.  How do you deal with that?
