Prof. Krishna Jonnalagadda

PROBLEM 1:

Draw the front view, top view and a suitable side view of the object given below.

The arrow indicate the direction from which the front view should be observed.

First of all observe the

isometric object given to you.

Draw the projection lines

and complete the front view.

FRONT VIEW

STEP 1

Transfer those projection lines

from front view to top view and

draw the top view.
