The Application of CAD in the Study of Truck Driver's Field of Direct Visibility 872293

This paper describes how Computer Aided Design (CAD) technology is used by a U.S. truck manufacturer to define and evaluate certain aspects of the driver's visibility. CAD programs and 3-dimensional techniques were developed to replace 2-dimensional drawing board practices that are time consuming and cumbersome. This paper specifically describes how CAD technology is used to 1) establish the driver's direct field of view, 2) define and evaluate the effectiveness of the swept area of the windshield, and 3) determine the obscuration of the instrument panel by the steering wheel.
