Scales

It is not always possible to make the linear dimensions on a drawing the same size as real dimensions on the object drawn.

If the actual linear measurements of an object are drawn in its drawing, called full size scale.

 Smaller object drawn larger than the object, called enlarge scale. Whereas big objects drawn smaller than the object, called reducing scale

Objects drawn in small & large scale, so that the drawing can be read & understand easily.

Types of scales:-

1.       Plain scale

2.       Diagonal scale

3.       Vernier scale

4.       Comparative

5.       Scale of Chord

6.       Isometric
