Working DrawingsUsually consists of a
front, side and plan view of the solution.
Sometimes there are two views but this depends on the complexity of the solution.
Working DrawingsDimensions are added so that any person
using the working drawing can manufacture the design.
Working DrawingsUsually there are at
least six dimensions but you can add as many as you feel are required in order for the manufacturer to make your solution.
Working DrawingsDrawing should be precise
and drawn to a scale. If the drawing is full size of
the solution then the scale is 1:1.
If the drawing is half the size of the solution then the scale is 1:2.
If the drawing is a 3rd the size of the solution then the scale is 1:3.
