ooohhh, passion invoked.
I used to do mech / elec dwgs for THE MAN. now I do "architectural" for the wife.......
I used to cuss dimension strings on my technical dwgs, files we got from arch firms, because the arch could not find his rear with both hands. I mean, his strings did not add up and I wanted my ductwork to FIT.
( if you are an architect, and you are reading this, you are FAR MORE SAVY ON THE COMPUTER THAN 99% OF THE ARCHITECTS I WORKED "WITH" )
now I seldom draw ductwork, but when I do, my dimension strings are things of beauty. not only do the ALL WAYS add up, no diddling with one number without moving the wall it was tied to, but I keep in mind the damned framer and how he is likely to be laying out the walls.
the thing he is measuring FROM better be there FIRST........ construction sequence wise.
and my dimension strings GO ALL THE WAY THROUGH whenever possible. I don't make you look for the right string to find the number you want. I don't make the framers THINK, that's what I get paid to do, and frankly, I am better at it.
that being said, I like tick marks for dimensions and arrow heads for leaders.
I am unable to conceive dimensions snapping one on top of the other. sounds like sloppy drafting to me. if brevity is the soul of wit, then minimal dimensions are the framer's nirvana. but (PREGO) it's in there.
BUT IT COULD JUST BE THAT I HAVE NOT WALKED THE MILE IN YOUR SHOES. so don't take it personal.
think I need a beer.
