Question

If an object is placed in 1st 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 had been asked this question in homework.

The doubt is from First Angle Projection Method in portion Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

The correct answer is (c) The top view touches the reference line

Easy explanation: In the first angle projection the projections of object is taken by placing object in 1st 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.
