Scales

Abstract

Drawings of buildings/machines are prepared adopting a scale, and the scale adopted is to be mentioned below the drawing. If a drawing is made of the same size as the object, the view obtained will have the same size as the object. The drawing thus obtained is called a full size drawing and the scale used is called full size scale. If the object is larger in size, its drawing cannot be accommodated in the standard size drawing sheets. Hence, the drawing is made smaller in size. The scale used for this type is called a reduced scale. Objects of smaller sizes require drawings of larger in size. The scale used for drawing such components is called an enlarged scale. A scale is used to prepare a reduced or an enlarged size drawing.
