Application of 3D CAD for Basic Geometric Elements in Descriptive Geometry
Abstract
This informal study integrates the solutions in descriptive geometry with an introduction to 3D CAD approach for dealing with the basic geometric elements. The basic elements include points, lines and planes as opposed to solids. Several problems in descriptive geometry were solved using both the 3D CAD approach and the traditional approach that requires successive auxiliary views based on orthographic projection. An evaluation of both approaches was conducted. It showed that the use of 3D CAD in descriptive geometry demonstrated the effectiveness in speed and accuracy, and did not limit the use of geometric and spatial reasoning.
