This was a reasonable measure for the interim but for the longer term, amore integrated offering was desired. A replacement course has now been developed and wasfirst offered in September 2016.The first year course taken by all engineering students in the college, and a prerequisite for thiscourse, includes the following topics: isometric and orthographic drawings and translations backand forth between the two, freehand sketching, section and auxiliary views, scaling anddimensioning, lettering, titles, borders, and interpretation of

Moreover, instructors often cannot keep pace with the latestvirtual technology software developments.To address this problem, a number of universities are introducing innovative curricula withcomputer-aided design (CAD) modeling and computer-aided engineering (CAE) analysis tools tohelp promote a better understanding of engineering basics and fundamentals among students,with the ultimate goal of preparing engineers who can fully integrate computer modeling anddesign with analytical skills.1 Researchers at the Department of Mechanical Engineering at

general, and particularly in the construction industry. Most highschools in the United States and Canada now offer Auto CAD and other CAD software classesfor their students [7]. Many Construction Management programs in the US offer CAD trainingas part of their curriculum.Teaching CAD applications is especially challenging when there is a large gap in the students'backgrounds. Many attempts were made to make CAD instructions practical and enjoyable tostudents with different backgrounds [1], [2]. While students with previous knowledge of CADobtained in high school expect advanced CAD instructions related to the constructionmanagement, students with no previous CAD experience expect basic CAD instructions at first,and before advanced CAD

Also, a creative problem solving course 1 wastaught for general engineering; it was open as a technical elective to all other students. However,after 2000, when the university switched from a quarter to a semester system, a common firstyear was instituted for all engineering students, and creative problem solving was no longerincluded in the curriculum, except as a one-credit module in the Engineering Enterprise Program.The two-semester capstone design course in the Mechanical Engineering-Engineering

It is estimated that at least 84 majors consider thespatial visualization a fundamental need (Smith, 1964) and in technical jobs, such as thedifferent types of engineering, the abilities to visualize are especially important (Maier,1994)2.The third reason that justifies this study is that educators need to continually analyze andinvestigate their own teaching to be more effective educators (Fernando Hernandez,1992) 3.Previous analysis and current situationThe visualization of parts in the multiview projections system, in other words, theinterpretation of views of an object represented by its technical drawing, is

in each area and looks athow the improvements came about. The authors noted many improvements based on theassessment data; however, the most significant changes with the most impact on the studentscame from innovation, not assessment. So, while assessment plays a key role especially inincremental improvements, innovation still plays an enormous role in improving courses.I. IntroductionPrior to the 2000 paradigm shift, ABET accreditation was referred to as a “recipe”1.Unfortunately, the ingredients of the recipe were never mixed.

Nearly all of the students withexperience took some sort of course in high school. Most of these high school courses taughtAutoCAD as the CAD software. A few students had courses that included 3D solid modelingsoftware in addition to AutoCAD. These courses were evenly split between SolidWorks andInventor.Table 1 shows the results from the pretest and posttest for both the inexperienced students andthe experienced engineering graphics students.

A survey was given at the beginning of the semester and students were asked toevaluate their proficiency in ergonomics compared to other subjects such as CAD or PLM. Out ofthe fourteen responses we collected from the students, the average was around 1.5 out of afive-point scale where 5 being the best and 1 being the worst. A test was given at the end of thesemester, and out of the fifteen responses, the average of students’ self-evaluation in theirergonomics knowledge raised from 1.5 to 3.4, again out of a five-point scale.

more credible. The models werecompletely textured to add detail and digital photography was added for views out of thewindows for added realism. Throughout this paper we will be looking at two different views ofthe model to show examples of the specific lighting techniques.ModelingThis project was modeled in Maya using a combination of polygons and nurbs (Figure 1 & 2). Itwasn’t modeled with an eye towards geometric detail, but rather simplicity in texturing andrendering. The idea was that we would attempt photographic quality through texturing andlighting rather than geometry. The model isn’t heavy to work with and most objects are ondisplay layers so they can be turned off for ease of use

Future success as a student and as a professional in manyareas, both technical and non-technical, can be dependent on this ability to manipulate 3Dspace and objects within that realm [3, 4, 5]. Research in this field has also shown thatspatial capabilities can be strengthened through appropriate instruction [6, 7, 8].

See Fig. 1 for a solidmodel of the PMR device. The choice to use a four axes device was based on experimentationthat showed an improvement in rotational ability of the object over a three axis device and adesire to keep the complexity of the system to a minimum. An object has 3 rotational degrees offreedom; however, due to the physical limitations of the PMR, more than 3 axes are required torotate the object about each of its rotational degrees of freedom at a given instance.
