Scale 1

When a technical drawing has a scale of 1:1, it means that a dimension which measures 10mm on the drawing, measures 10mm on the actual component.

• 10mm

• 5mm

• 20mm

Scale 2

When a technical drawing has a scale of 1:1, it means that a dimension which measures 10mm on the drawing, measures 10mm on the actual component.

 

If a technical drawing has a scale of 1:5 and a dimension measures 10mm on the drawing, what would the dimension be on the component?

• 5mm

• 2mm

• 10mm

• 15mm

• 50mm
