21
Q

Used to draw horizontal straight line

22
Q

Used to guide the triangles when drawing vertical and inclined lines

23
Q

Used to construct the most common angles (i.e. 30°, 45°, 60°) in technical drawings

A

Set-square

24
Q

Used to draw parallel and perpendicular lines quickly and conveniently

A

Set-square

25
It is used for laying out and measuring angle
Protractor
26
A number of kinds of scale are available for varied types of engineering design
Scale (ruler)
27
It is used to draw circles and both in pencil and ink. It consists of two legs pivoted at the top. One leg is equipped with a steel needle attached with a screw, and other shorter leg is, provided with a socket for detachable inserts.
Compass
28
Used chiefly for transferring distances and occasionally for driving spaces into equal parts. i.e. for dividing curved and straight lines into any number of equal parts, and for transferring measurements.
Dividers
29
Used for pencil work
Detail Paper
30
Used for finished drawing
White Drawing Paper
31
Used for both pencil and ink work and useful for replicating a master copy
Tracing paper
32
To indicate all visible outlines/boundary of an object. It shows the shape of an object
Visible line/ Object line
33
To represent hidden edge of an object. They should end on both sides by touching the visible lines and should touch themselves at intersection
Hidden line/dashed line
34
To show a line passing through center of hole, pitch line etc
Center line
35
To show dimension of an object
Extension line, Dimension line and leaders
36
To indicate cut portion of an object
Section line
37
To show imaginary cutting of an object
Section line
38
To show imaginary cutting of an object
Cutting plane line
39
To show break of an object in order to shorten the view of a long part
Break lines
40
To show alternate position of an object of the position of an adjacent part
Phantom line/Repeat line
