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.
