ISOMETRIC PROJECTIONS

MULTIPLE CHOICE QUESTIONS (MCQ)

WITH ANSWERS

MCQ on isometric projections

increase knowledge and

understanding as well. It is very

helpful in all types of projections.

It gives the 3 dimensional picture

of the object. In this, dimensions

are 84 % of the true dimensions.

For drawing the isometric

projections, isometric scale is

constructed and used.
