Scale in the context of graphic communication (Graphic Scale) - ✔✔Ratio of a measuring unit to the full-
size item it represents, ex: 1/4" = 1'-0". Makes it possible to represent a very large object on a piece of
paper while showing accurate proportions.
A Scale - ✔✔Instrument used in manual drafting that facilitates making and reading scaled drawings
Architect's Scale - ✔✔Uses fractions of an inch (or multiples of an inch) to represent feet and inches.
most common scale is the 12 in triangular scale, which contains 12 scales along 6 edges.
Metric Scale - ✔✔Used when a project is planned and represented in SI (metric) units. Divided in
proportions like 1:50, 1:10, 1:5. Ex: on the 1:50 scale, one scale unit equals 50 units of the actual size
(similar to 1/4" scale, which works out to 1/48)
Engineer's Scale - ✔✔Indicates feet and fractions of a foot and uses scales such as 1" = 40' or 1" = 100'
Used by civil engineers
Although they are available on many architect's scales, ___ & ___ scales should never be used because
___ - ✔✔3/32 and 3/16
they are too close to 1/8" & 1/4" scales
Typical scale of floor plans of very large buildings - ✔✔1/16" (1:200)
Typical scale of floor plans - ✔✔1/8" (1:100)
Typical scale of floor plans, simple interior elevations, & building sections - ✔✔1/4" (1:50)
Typical scale of complex interior elevations and complex building sections - ✔✔3/8" (1:30)
, Typical scale of enlarged floor plans and very complex elevations - ✔✔1/2" (1:20)
Typical scale of enlarge floor plans and full wall sections - ✔✔3/4" (1:20)
Typical scale of simple details (not often used) - ✔✔1" (1:10)
Typical scale of ceiling details and simple cabinet details - ✔✔1-1/2" (1:10)
Typical scale of doors, cabinet, furniture and similar details - ✔✔3" (1:5)
Typical scale of cabinet details and other complex details - ✔✔half full size (1:2)
Typical scale of very complex details - ✔✔full size (1:1)
Graphic Scale On a Drawing - ✔✔Band of alternating light and dark portions, each representing a certain
length. When these are used, measurement of scale is not dependent on having a scale instrument.
Useful when drawings are reproduced at an odd size for presentations or publication.
Orthographic Drawings - ✔✔Use projection so that a 3D object may be presented in 2D. Useful for
paper, as multiple views can accurately and completely describe even complex objects.
Orthographic Projection - ✔✔View of an object seen as though the viewer's line of sight were
simultaneously perpendicular to every point on the nearest face of the object. Each face is projected
onto a flat, transparent plane parallel to that face.
Scale and proportion are the same for multiple views, however when a diagonal line or plane is shown,
it is foreshortened.
Most common types of orthographic drawings: - ✔✔- Floor plans
- Reflected ceiling plans
