Question

If an object is placed in 3rd quadrant such that one of the surfaces of object is coinciding with vertical plane, what is the correct position of views from the following?

(a) The front view touches the reference line

(b) The side view touches the reference line

(c) The top view touches the reference line

(d) The bottom view touches the reference line

I have been asked this question during an online exam.

My question is taken from Third Angle Projection Method in chapter Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

Right choice is (c) The top view touches the reference line

The best I can explain: In the third angle projection the projections of object is taken by placing object in 3rd quadrant. If the object’s surface is coinciding the vertical plane which indirectly saying the distance from vertical plane is zero so top view of that object touches the reference line.
