1. CLASS 5 Review: Scales Lab:
!!! Complete scales exercises and show it to instructor during this class (metric, engineer, architect)
!!! Complete “Mastery Test” and show it to instructor during this class
!!! Review “Triangle exercise” given in class 3
Home work:
“Multiview Skething Problem 2-3”. Turn in for grading on class 6 (06/04) chapter 4 from the book

2. The Metric System - SI 1mm=1millimeter (1/1000 of a meter)
1cm= 1 centimeter =10 mm (1/100 of a meter)
1dm=1 decimeter=10 cm= 100mm (1/10 of a meter)
1m = 100 cm= 1000mm

3. SCALES
Metric Scale
Metric Scales used in map drawing and drawing force diagram.
Full Size 1:1 (1:10, 1:100, 1:1000)
Half Size 1:2 (1:20, 1:200, 1:2000)
Other scale ratios on a scale 1;5, 1:25, 1:75.

4. Engineers’ (Civil Engineers’) Scale
SCALES
Engineers’ (Civil Engineers’) Scale
An Engineer Scale is a decimal scale graduated in units of 1” divided into
10, 20, 30, 40, 50, 60 parts. This type of scale is convenient for machine drawing,
Site plans, and drawing stress diagrams.
Scale Ratios:
1”=1’, 1”=10’, 1”=100’, 1:1
20 1”=2’, 1”=20”, 1”=200’, 1”=2’ 10 20 40 30 60 50

5. SCALES
Architect Scale
Used in Architecture, Piping.

6. SCALES In this presentation you will find examples
of metric, engineer and architect scales.
