Scale: scales are graduated in inches and are usually represented as fractions of different values \u200b\u200bthat equal 1 inch. STANDARD SCALES
Natural Scale
: is used for graphical representation of objects that have the same dimension in both the drawing and the reality. Its normalized value is represented as follows: ESC.1: 1
Scale Reduction: used for graphical representation of objects that have a greater dimension than the drawing. Their normalized values \u200b\u200bare represented as follows: ESC.1: 2,1:5,1:10,1:20,1:50 ...
Scale Expansion: is used for graphical representation of objects that have a greater dimension than the drawing. Their normalized values \u200b\u200bare represented as follows: ESC.2: 1,5:1,10:1 ....
