MULTIVIEW DRAWING
The purpose of a Multiview Drawing is to
represent a three dimensional object on a two
dimensional sheet of paper or in a two
dimensional drawing space.
Multiview Drawings are used by Engineers,
Architects and Contractors to Design and

Dimensioning
Process of adding size information to a
drawing
A well dimensioned part will communicate
the size and location requirements for each
feature
Parts are dimensioned based on two criteria:

Scales
The purpose of scales is to allow an
engineer, architect, technician or
contractor to determine scaled
measurements from drawings or maps
very quickly and easily.
Drawings and maps are drawn to
different scales such as: 1 = 100, 1 =
1-0 or 1:2 (h
