Question

Which is the wrong statement regarding dimensions?

(a) Every dimension must be given, but none should be given more than once

(b) Every dimension should be written to the left side of the drawing

(c) Dimensions should be placed outside the views

(d) A centre line should not be used as a dimension line

This question was addressed to me by my school teacher while I was bunking the class.

I'd like to ask this question from Types of Dimensioning topic in division Lines, Lettering and Dimensioning of Engineering Drawing

Answer 1

Correct option is (b) Every dimension should be written to the left side of the drawing

For explanation: There is no such rule that the dimensions should be placed only on left side of drawing because it may not possible to represent every dimension only on left side. So, it is given flexibility that dimensions can be given any side of drawing but none should be given twice or more.
