1. Production drawing of a part of a machine is also called a _______
a) working drawing
b) installation drawing
c) machine drawing
d) sub-assembly drawing
Explanation: Production drawing is also termed as a working drawing or a part drawing. It is a detail drawing of each part of a machine. These working drawing is quite useful for each step in the manufacturing industry.
2. Which type of drawing is supplied by the manufacturer to the client?
a) Tabular drawing
b) Assembly drawing
c) Client drawing
d) Installation drawing
Explanation: Installation drawings are the drawings supplied by the manufacturer to the client. It gives the overall dimensions of the assembly which may be needed at the time of installation. Details of foundation holes are an example of installation drawing.

a) square shape
b) same size and same shape
c) same shape but different sizes
d) different shape but same size
Explanation: Tabular drawings are used for parts that have different dimension but same shape. In that case, the drawing can be dimensioned with sizes as P, Q, R, S, etc. The values of P, Q, R, and S can be tabulated in the table. Here dimensions of different parts are calculated by taking relative ratios directly.
4. Patent drawing must be in a pictorial view.
a) True
b) False
Explanation: Patent drawings are used to get a patent of a machine or machine component. The drawing may be in a pictorial view or in orthographic view as required for patent work depending on the complexity of the part. Both types of views can also be drawn if required.
5.___________ is used to communicate information to industry.
a) design data
b) installation drawing
c) machine drawing
d) patent drawing
Explanation: Machine drawing is a drawing of machine elements. Design data may not be readable or easy to interpret to everyone in the industry and installation drawing gives overall dimensions of assembly. Hence, only machine drawing is used to communicate information to industry.
6. Working drawing is used by ______
a) production department
b) customer
c) marketing department
d) designer

b) Wide Coordinate system
c) World Coordinate System
d) World CAD system
Explanation: 3-dimensional coordinate system with X, Y and Z axes considered up to infinity is termed as WCS. WCS is an abbreviation of World Coordinate System. Icon of WCS is shown at the lower left corner of drawing area.
9. Which type of coordinate system is used in AutoCAD?
a) 2-Dimensional
b) 3-Dimensional
c) 1-Dimensional
d) User dependent
Explanation: Coordinate system is used in AutoCAD is a 3-Dimensional coordinate system. The axes of this coordinate system are considered up to infinity. This coordinate system is termed as the World Coordinate System.
10. Origin of User Coordinate System _________
a) must coincide with WCS
b) at the left lower corner of drawing area
c) at the center of drawing area
d) can be anywhere in the WCS
Explanation: Origin of UCS can be anywhere in the WCS. It may or may not coincide with WCS. It can be moved/shifted anywhere in the drawing area.
