Answer 2

Question:

8. If an object is lying below HP 4 points  and in front of VP. then object

is at ............

(A) first quadrant

(B) second quadrant

(C) third quadrant

(D) fourth quadrant​

Answer:

(D) fourth quadrant​ is the correct answer.

Explanation:

Question is related to Orthographic Projections.

Position of reference place is similar to quadrants of x,y plane coordinate system. In that coordinate system 4th quadrant which lies below x-axis and in front of y-axis which is same as below H.P, in front of V.P.

Orthagraphic Projections are those drawings in which we draw different views of object which gets projected on various reference planes.

To draw projections of object we should have following information:-

1. Object

2. Observer

3. Location of Object => Position is seen with reference with Horizontal Projection or Vertical Projection.

Different Reference planes => Horizontal Plane (HP)

, Vertical Plane (VP)

, Side or Profile Plane (PP)

Different views are =>

1. Front View (FV) which is Projected on Vertical Plane (VP)

2. Top View (TV) which is Projected on Horizontal Plane (HP)

3. Side View (SV) which is Projected on Profile Plane (PP)
