Thanks J, the fog is slowly lifting. Let's see if I have it right-
File/ Page setup/ Print setup, printer/paper size determines the size of the
paper in my printer, say, Letter. If I set Zoom to fit 1:1, whatever I do
after here will be scaled to 8.5x11.
File/ Page setup/ Page size/ Page size determines the XY ratio of the
drawing page that I see on my screen. This will be shrunk (or stretched?) to
fit on the paper size when I print.
File/ Page setup/ Drawing scale/ drawing scale tells me what the real world
dimensions are represented by the drawing page.
So.... if the space I want to map is 100' x 500', and I want to print it on
8.5x11 paper, paper size = 8.5x11, Zoom = 1:1, Page size = 10x50(? doesn't
really matter?), drawing scale = 1:10. (I'd probably use 1:12 to give me some
room around the edges).
I think what happened is I started playing around with some of these
settings but I didn't make note of what the original settings was. After that
I was messing around with 4 variables. The odds of getting something usefull
is pretty slim.
