Implementing 3-D Modeling for Engineering Freshmen

Paul H. Zang, Dale Eddy, Judson Singer Kettering University

Abstract

Kettering University has begun a process of replacing the existing 2-D CAD software (AutoCAD) and replacing it with an integrated set of CAE (SDRC Master Series) and PDM software. The integration of a single source of data for many CAE operations allows the faculty to teach using a powerful set of tools beginning in the freshman year.

Solid modeling techniques, which stress the design intent of the model, enhance the skill set of freshman engineers and excites their interest on the mechanical engineering process. As a 100% co-op educational institution, the Kettering student skill with 3-D modeling tools early in the education process makes them more valuable to their co-op sponsor. Many of the University major sponsors have focused their CAE environment with a single data solution that eliminates the need for data translation and enhance their global communication.

I. Introduction

Communicating graphical engineering design intent from one person to another has been difficult for thousands of years. The designers and builders (engineers) of the pyramids in Egypt to the great churches in Europe constantly struggled with the laborers (manufacturing) to maintain the design integrity and intent of the structures. Unfortunately, the builders of old also had the bad luck to be placed at the top of any structure they designed during construction. If the structure gave way, typically the monarch would be looking for a new builder.

During the last ten years, many engineering education institutions switched from manual drafting for communicating design during the freshman year to 2-D drawing programs like AutoCAD, and CADKey. Recently, due to information and advice provided by engineering departments Industrial Advisory Boards and surveys (http://singer.kettering.edu/graphics_thread_emplo yers.htm) , solid modeling programs such as Pro/Engineer, UniGraphicsII, I-DEAS Master Series and Catia have been introduced to the engineering drafting/drawing programs in the freshman years as shown in the picture on the right.

Manual drafting and detailing continues to remain a critical need of the engineering industry, but
