Scales and dimensioning 2015

In the drawing: Using the ruler, we measure The bench’s length: 80 mm

The real length of the brench is read on the dimension number: 2000 mm

The scale’s ratio is how many times the reality contains the drawing: 2000 : 80 = 25



Scale : 1:25

The real length of the brench is read on the dimension number: 2000 mm

If we want to draw the bench using a new scale now: 1:20 We have to divide all real dimensions by the scale’s ratio: 2000 : 20 = 100 ďƒ

the drawing dimension is now 100 mm

Scale: 1:150 Length of the truck Height of the truck

In the drawing: Using the ruler, we measure The truck’s length: 87 mm The truck’s height: 36 mm

Scale: 1:150 Length of the truck Height of the truck
