1. Orthographic projection is drawn using two methods which is ________
a) Second angle and third angle method
b) First angle and third angle method
c) First angle and fourth angle method
d) Second angle and fourth angle method
Explanation: Orthographic projections of the object are drawn using first angle method and third angle method. In first angle method the object is placed in first quadrant. In third angle method the object is placed in third quadrant.
2. The method in which the object is placed in the first quadrant is known as __________ method.
a) third angle
b) second angle
c) first angle
d) fourth angle
Explanation: In the first angle method, the object is placed in first quadrant formed by the principal planes. In this method the top view is drawn at the bottom of the front view and right side view is drawn on the left hand side of the front view
3.In first angle method the top view is drawn _______ of the front view.
a) above
b) right Side
c) Left Side
d) bottom
Explanation: In first angle method, the top view is drawn at the bottom of the front view. In this method, the right hand side view is drawn on left side of front view. First angle method is mostly used in orthographic projection. It is easy for understanding
4. In third angle method the top view is drawn _______ of the front view.
a) above
b) right Side
c) Left Side
d) bottom
Explanation: In third angle method, the top view is drawn above the front view. Front view is drawn in the third quadrant and right side view is drawn on the right side of the front view. It is difficult for understanding as compare to first angle method
5. In ______ method the plane of projection is transparent
a) third angle
b) second angle
c) first angle
d) fourth angle
Explanation: In third angle method the plane of projection is transparent as compare to first angle method. In third angle method the object is shown in the third quadrant with transparent planes. This method is used in United States of America.
6. On which drawing basic command is mostly used?
a) Two dimensional views
b) Three dimensional views
c) Four dimensional views
d) Five dimensional views
Explanation: The two dimensional views are drawn separately in the drawing. Two dimensional views are drawn with the basic entities or command. It easily draws on the drawing
7. The drawing in which both the commands are used i.e. basic and modified command the view is known as _________
a) two dimensional views
b) three dimensional views
c) four dimensional views
d) five dimensional views
Explanation: The three dimensional view is not drawn easily as compare to two dimensional view. The three dimensional view is drawn with the help of basic and modern entities o commands. It is the most important type which is used in drawing.
8. If the total detail is not obtained from the three directional views the ______ is drawn.
a) pictorial view
b) oblique view
c) perspective view
d) two dimensional view
Explanation: Pictorial view is the advancement or modification of three dimensional views. Pictorial view is drawn or used when the three dimensional view is not easy or confuses the detailing of the object.
9. Which of the following is a pictorial view?
a) Isometric view
b) Cavalier view
c) Axonometric view
d) Cabinet view
Explanation: Pictorial views are axonometric view, oblique view and perspective views. Pictorial view is drawn for the complex object which is not draw from the three dimensional view. Cavalier view, Cabinet view, Isometric view are not the types of pictorial view.
10. For __________ an object is first rotated in horizontal plane about a vertical axis to make an angle with the picture plane.
a) isometric view
b) axonometric view
c) cavalier view
d) cabinet view
Explanation: An object is first rotated in horizontal plane about a vertical axis to make an angle with the picture plane is called the Axonometric view. It is then tilted at an angle to which it touches the picture plane. Axonometric view types are Isometric, Diametric and trimetric views
