Instructor and student reactions to the newlydesigned course are discussed, including their views on the relevancy, work load, and overallreaction.IntroductionThe University of Wisconsin-Marathon County (UWMC) offers a two-year pre-engineeringprogram. The purpose of this program is to give students the core engineering courses they needduring the first two years in college. After completing the first two years, they transfer into oneof many engineering programs at many universities. The curriculum of such a pre-engineeringprogram must encompass necessary courses students need regardless of which specific major oruniversity they transfer. Engineering graphics is one course which

the 1960’s developed curriculum projects titled “IACP” and “Jackson Mills” that led to thenew curriculum in technology education that provides more than just skill-based training, but curricula that developsstudents literacy in critical thinking, problem-solving and design. Donald Maley and the research andexperimentation emphasis in his “Maryland Plan” in the 1970-80’s and the national focus on design in the 1990’shas made technology education one of the main catalysts for pre-engineering education6. This can also easily berecognized in the “State Career Clusters” curriculum project in 2001 that established needed standardization forcurriculum related to science, technology, engineering, and mathematics (STEM) from the US Department

spatial visualization skills.An interactive multimedia software based on work by Sorby and Baartmans1 and a 3Dsketch-based solid modeling software (Pro/Engineer) were utilized in the class. Theinteractive media provided students with the opportunity to gain fundamentalunderstanding of orthographic projection, rotation about one or more axes, reflection andsymmetry. Pro/Engineer was utilized to create solid models and project them at differentangles, enabling students to realize various mental visualizations. Preliminary assessmentof the class indicated that combining the interactive media and the solid modelingsoftware was effective in the development of spatial skills in undergraduate engineeringand technology students. The assessment also

University Calumet, we useassessment measures which include faculty evaluation, class critiques and written peerevaluations that individually addresses each level of technical, aesthetic and creative aspects ofeach project or assignment. Discussions or critiques first address the success of technical aspects,then move to the aesthetic aspects, and then the overall creative attributes of the students’ work.This type of evaluation is not only valuable for the students to comprehend each level and puttheir soft skills to work, but also provides valuable assessment feedback to the faculty.The CGT program is relatively new, having been started in the year 2000 with 18 students, andhaving grown to its present size of about 200 majors. The program has

environment, by creatingdepth (Z-axis) cues for the space to which the object belongs. The depth information provided instereo images can help users perceive geometric and design features more clearly, morerealistically, and more accurately than traditional 2D projection views. Therefore, stereo VRdisplay systems can help users more fully understand design objects, when compared withconventional 2D display systems.Currently, there are several different methods for generating a stereo view of a 3D object. Themost popular stereo display methods include: anaglyphic, polarized, line interlaced, frameflipping, and sync doubling. Each stereo display method characteristically has its own strengthsand weaknesses.Both anaglyphic and polarized stereo systems

Purdue University has been engaging in PLM-related activities since1999. Through the strategic partnerships and collaborative projects with industry and softwarevendors, Purdue University has built a strong reputation in the PLM area during the past six years.While many industries are interested in PLM, Purdue University has learned from our industrycontacts that there is currently a great shortage of PLM-literate

We’ll becovering the techniques in conjunction with a case study that shows the application of theconcepts. This paper will provide a workflow, some real numbers along with real renders tomake the numbers visibly understandable, and some indication of the time costs of the variousoptions. It should enable anyone to be able to start incorporating these lighting techniques intotheir workflow.The project for this case study was modeled and textured in Maya.

We ask engineering students who have spent their academiclives studying calculus, physics, and the like to be creative or to think on the right side of theirbrain. Storyboarding can be another tool for developing visual problem solving andcommunication skills.Laseau describes Graphic Thinking as “thinking assisted by sketching.” He further states thatgraphic thinking is usually “…associated with the conceptual design stages of a project in whichthinking and sketching work closely together as stimulants for developing ideas.” (Laseau, 2001)According to Barr (1999), sketching is a quick and easy way to express ideas manually. It is anatural psychomotor process of

The deck servedas a useful capture device only when the camera was being used to shoot raw video, and post-production was beginning on another part of the multimedia project, and the projects were shoton Mini-DV tape, rather than via the Laird Cap-Div. Camera issues:Issues with the camera, Canon XL1s, were explored to see if the extensive defects related to theoriginal XL1 have transferred over into this model. The first few of the notable issues with thecamera were: (1) the viewfinder’s sensitivity to light and potential for

to learn and use 3-D solid modeling packages? In the fall of 2005, a study was undertaken at MichiganTechnological University to answer these questions. Two different tests were administered at thebeginning of an introductory engineering course to determine the students’ level of spatialability: the Purdue Spatial Visualizations Test: Rotations and the Mental Cutting Test. In theintroductory engineering course, students receive five class periods of instruction in engineeringgraphics (isometric sketching, orthographic projection, rotations, and other topics) and threeclass periods of instruction in a 3-D solid modeling package. Some of the students receivedinstruction in engineering graphics before learning 3-D modeling software, and some
