This interesting question is from Basic Principles in Dimensioning in section Lines, Lettering and Dimensioning of Engineering Drawing

Answer 1

The correct choice is (b) 3 x 45˚

The best explanation: A chamfer of 3mm thickness and angle 45˚ is dimensioned as 3 x 45˚. From this dimension, we can get the information of the angle at which the chamfer is cut and the distance from one of the sides. This helps in the reading of the dimensions easy.
