The document discusses scales used on engineering and architect scales and for measuring drawings. The 10 and 16 scales can be used as rulers. Scales are used to measure lines on drawings and reduce or enlarge drawings. If a drawing has a scale of 1/8" = 1', the architect scale should be used to measure. Examples show how to determine actual lengths from measured lengths on drawings using given scales.

the part on the plan is 4.0”,what is the actual length of
the part?
