1. Parallel to each other and perpendicular to projection plane
2. Not parallel to each other and perpendicular to projection plane
3. Parallel to each other and inclined to projection plane
4. Not parallel to each other and inclined to projection plane

 

3. All the faces of the object are distorted in the shape and size.

1. True
2. False

 

4. Which of the following statement is wrong in case of oblique projection?

1. The object is drawn with the reduced dimensions
2. Projectors are parallel to each other and inclined to projection plane
3. The choice of the position of the object depends upon the shape and size
4. The faces of object which are perpendicular to the plane of projection will be distorted
    

5. When the receding lines are drawn to full size scale then the oblique projection is

 

 

 

1. Cabinet projection
2. Isometric projection
