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.
