BASIC DRAFTING SYSTEM

The basic drafting system requires an accurate table

and constant attention to the positioning of the tools. The

system includes the ability to change the angle, thereby removing the need for the

triangles as well.

Computer Aided Design

Replaced manual drawing Can be 2-dimensional or 3-dimensional.
