Question

What is the scale ratio of full size scales?

(a) 1:2

(b) 1:3

(c) 1:10

(d) 1:1

I got this question by my college professor while I was bunking the class.

Origin of the question is Scales topic in division Lettering Practice, Scales & Curves of Civil Engineering Drawing

Answer 1

Correct option is (d) 1:1

For explanation: As the name suggests it does not make any changes in the scale, no increment or decrement to the figure is done. The dimensions for drawing will be full, same in proportion and size as the actual object dimensions.
