Introduction to computer aided drawing, Geometrical
constructions, Orthographic drawing and sketching, Three-dimensional drawing, Dimensioning
principles, Sectioning and conventions.
A new machine, structure, or system must exist
in the mind of an engineer or designer before it can become a reality. Design
process is an exciting and challenging effort, during which the engineer uses
graphic language as means to create record, analyze, and communicate design
concepts or ideas.
The engineer or designer must understand how to
read and write in the graphic language. Engineers and designers must be able to
create idea sketches, calculate stresses, analyze motions, size parts, specify
materials and production methods make design layouts, and supervise the
preparation of drawings and specifications that will control the numerous
details of product manufacture, assembly and maintenance. To perform or
supervise these many tasks, engineers communicate to others through freehand
sketches or drawings created using Computer Aided Design or Computer Aided
Drafting (CAD). Preliminary sketches are followed by more exact sketches and
the drawings as the idea is developed more fully. CAD can help you create
drawings, but it takes skill to know which drawings and what level of detail is
required at each design stage. While CAD has replaced traditional drafting
tools for many design teams, the basic concepts of graphic communication remain
the same.
