Graphical Projection - Overview

Overview

The projection is achieved by the use of imaginary "projectors". The projected, mental image becomes the technician’s vision of the desired, finished picture. By following the protocol the technician may produce the envisioned picture on a planar surface such as drawing paper. The protocols provide a uniform imaging procedure among people trained in technical graphics (mechanical drawing, computer aided design, etc.).

There are two types of graphical projection, categories each with its own protocol:

• parallel projection
• perspective projection

• Isometric projection.

• Oblique projection.

• Oblique projection.

• One-point perspective projection.
