An alternative to computer software is graph paper, an architect's scale
, and colored pencils.
Gridded vellum contains a grid of light blue lines that will not reproduce at regular photocopy or diazo (blueprinting) process contrast settings and is available for different scales (8 lines per inch for architect's scale drawings and 10 lines per inch for engineer's scale drawings).
Two scales that designers commonly use are the architect's scale and the engineer's scale (Figure 1-15; Figure 1-16).
Two types of scales are used for construction drawings--an architect's scale using fractional divisions, and an engineer's scale using multiples of ten (Figure 3-1).
Measuring lines with the architect's scale first requires finding the scale that matches the drawing being interpreted.
The architect's scale divides the inch in a number of ways that permit dimensions to be represented as feet and inches.
Using an architect's scale instrument to measure and a triangle as a straightedge, draw a line 18 feet long to the scale of 3/8" = 1'.
Two types of scales are typically used for plans: an architect's scale using fractional divisions, and an engineer's scale, using multiples of ten.
The reading of scales, particularly the architect's scale, takes some practice, but they are invaluable tools for interpreting plans.
Of all the tools, the children had the most difficulty with the architect's scale
An architect's scale
is the old standby that's shown at left.
To make things easier, you should get basic drafting tools such as a circle template, landscape template, a triangle, an architect's scale
, drafting tape, an eraser, a pencil sharpener, and tracing paper.
