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!

I'm sure that any of the older engineers on the list will be able to
confirm that the origin of the practice of not scaling drawings originated
from the fact that the liquid based printing processes of the 1950s and
1960s stretched the paper when printing.

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?
