I am working these HUGE McDonnell Douglas Mylar's; they haveno dimensions and are scaled 1:1. The block Tol is .XX=.03 and.XXX=.015

My idea was to scale and model the features as best I can and printthe SW Drawing 1:1. Then overlay the Mylar on the SW drawing tocheck my work. (The part fits on a 11x17 sheet 1:1)

I found that my printer is not accurate as I check longer featuresin the SW print out. (.025" over 15")

So I was wondering what else to do. I got another guy to measurethe Mylar and he got different numbers. I guess it's the use ofdifferent techniques.

I noticed that if I sketch two lines (vertical) in SW and add adimension (Horz)
Then increase the line font to something very fat the dimensionleader lines point to the center of the line (it splits thevertical line). Is that how we should scale the features on theMylar, to the center of the line, or from out side to out side?
