Implementation of computer graphics exercises in freshman engineering graphics education

Abstract

The rising application of computer-aided design (CAD) in the industrial environment has precipitated an interest in computer graphics for engineering education. At the University of Texas at Austin, a computer graphics laboratory has been established that is primarily dedicated to freshman engineering graphics education. The laboratory is currently equipped with eight Hewlett-Packard 2647 A intelligent graphics terminals. Five software modules have been developed to introduce the student to the graphics terminal and to demonstrate its capabilities for making engineering drawings. The modules permit the construction of line drawings, pictorials, graphs and charts on the CRT terminal without requiring any programming skill on the part of the student. The laboratory exercises have been successfully used by over 1000 engineering graphics students during the first two semesters of implementation. This paper describes the efforts to date in organizing and implementing this freshman computer graphics laboratory.
