ABSTRACT

Use of a CAD/CAM system makes changes in the methods of preparing a drawing inevitable. These changes, and their implication are described under the headings shown below:

Manual versus electronic

Ergonomics

Electronic drafting techniques

Use of "layers"

Electronic drafting and design analysis

The inversion of design

The role of a tablet

Let us look at them to gam insight on this new tool. Once we have a feeling for these changes, we can better understand how the system will affect other surrounding activities.
