In EDG II, studentsproduce a rapid prototype of their team design project. In this case students are not onlyable to see the visualization chain from sketch to computer model to part, but they canalso examine some of the assembly issues of their design. Within the assembly designsproduced in EDG II, the interface and fit between components can be simulated andtested.Pro/ENGINEER, I-DEAS, and Rhino are utilized in upper division manufacturing, plas-tics, vehicle design, and industrial design courses.

The focuses of this investigation are on: (1) how the CADsoftware is used as a visually driven design tool, (2) how the tool allows students to see andincrease their understanding the effects of different design parameters, and (3) what difficultiesstudents encounter while using the software.I. IntroductionCurrently in the industry, the CAE software packages have a wide range and sophisticatedcapabilities. They are becoming more and more user-friendly, easier to operate and master.Some of these software packages in the market today include Unigraphics, CATIA,Pro/ENGINEER, I-DEAS, etc. The capabilities of all

But to adequately expose the students to the many inter-related aspects of this broad industry in such a short time is a challenge.As reported in the literature1, faculty in the BEST program have been using the computer formany years to facilitate students’ understanding of aspects of the HVAC industry.

to quote a few opinions.“Although the computer test was faster to complete, I found I learnt more from performing thetest myself.”“The simulation is good because it is ‘purged’ from redundant details that you have in a real test.It is better as an introduction to the laboratory work, but it cannot substitute a physical lab.”“I don’t prefer the lab over the computer simulation or vice versa. The lab should not beexcluded from the curriculum as it provides useful hands-on learning. The computer simulationcould also be added as a supplementary addition to the course.When in the actual laboratory, we worked in groups of 6 people. Each person had theresponsibility of only one task (i.e. measuring height, time for flow rate measurement, etc

Standard numerical analysis techniques using MATLAB and the virtual prototypingenvironment provided by WORKING MODEL software are used. Students involved with theproject have expressed enhanced understanding of the subject matter with the integration of thesoftware tools. As expected, both simulation environments yield similar results, however, thevisual display of the motion using WORKING MODEL provides an excellent correspondencebetween the abstract mathematics and a realistic animation of the

Multimedia Lab Manual (IMLM)” differs from atraditional-printed lab manual: 1) unlike a bounded collection of papers of a type-written labmanual, multimedia-based lab manual can combine words, mathematical equations, simulation,pictures, sound, animation, and video for publishing information. 2) Most importantly and unlikeany traditional-publishing media, a multimedia-based lab manual can respond to interaction fromthe readers (students).The IMLM allows students to move through the computer-based document in the way that isrelevant to them, to jump specific places and pages, get further details of information, visualizelaboratory experiments by clicking buttons on a mouse.

For example, a group at Purdue Universityevaluated the use of computer-simulation experiments in a senior-level chemical engineeringcourse.1 They found that the computer-simulated experiments led to better learning for somestudents, while others got more out of a traditional lab experiment. The authors caution againstusing instructional technology without evaluating its effectiveness.The effectiveness of any instructional software for a given student depends on a variety offactors
