4. Scales Used for: Scale notation: Making measurements
Establishing dimensions
Drawing features at reduced size
Scale notation:
Usually noted on title block or below the view differing in scale

5. Scales (cont’d.) Types: Metric scale Architects scale

Architects scale
Contains 11 different scales
Civil engineer’s scale

1/8”=1’-0” Commercial

8. Engineer’s Scale - 6 different scales
Can be identical or different units
1”=20’ Common for ¼ Acre or less
1”=30’ Common for ½ Acre

9. Factors to Determine Scale:
Actual size of structure
Amount of detail to be shown
Paper size selected
Amount of dimensions and notes needed
Common practices (company)
DH uses 1/8”=1’-0” because print on 11” x 17”
Ivory uses 1/4”=1’-0” because use Arch C 24” x 36”
