DEVELOPMENT OF A MULTIMEDIA-BASED INTERACTIVE ENVIRONMENT FOR 3D SOLID MODELING TUTORIALS Zahed Siddique and Atif Qamar School of Aerospace and Mechanical Engineering University of Oklahoma, Norman, OK 73019

Abstract

3D solid modeling with CAD software is extensively used during design and development of products. There are several widely used CAD softwares available in the market. Training for students and individuals to use these CAD softwares are needed by both academia and industry. One of the primary media to provide training, including self-learning, is by using book and multimedia tutorials. These tutorials utilize text, snapshots, movies, etc. to facilitate learning of 3D modeling techniques for the CAD softwares. Usually the user reads the instructions and then tries to follow it using the software. Advancements in new multimedia technologies can provide higher level of interactions to facilitate the learning process. In addition, 3D web-based representations can increase understanding of creating 3D solid models and assembly processes for CAD software. In this paper we present an interactive training environment, where users are provided with interfaces in such a manner so that he/she can go though the steps of creating geometry in a simulated CAD environment. Multimedia tools are used to develop interactive 3D CAD tutorial in the simulated environment. In this paper the web-based interactive training environment has been developed for Pro/ENGINEER.

I Introduction

Engineering drawings are essential to exchange and communicate engineering information during design1,2. CAD softwares are used to generate three dimensional representations of design concepts. These three dimensional solid models, generated using CAD softwares, are used to support concurrent engineering. Software tools are available to perform analysis, create layouts, specify manufacturing process, etc. from the solid models, thus making the product design and development process more efficient. Most of the CAD softwares available in the market and used by industry allow development of solid models.

Engineering graphics and CAD software training can be divided into the following broad categories: Most academic institutions have one or more graphics and/or solid modeling courses in their curriculum to teach students basic graphics principles and how to use one of the available commercial software packages.
