MCT problems: 1)comprehend the object and cutting plane, 2) cut the object with the plane, 3) rotate the cut object,and 4) recognize and select the correct cross section from the possible solutions. Saito et al.87later revised these steps to include identifying the quantity in the cross section after the rotationstep. Analysis by Saito et al. clarified that MCT errors rarely occurred in the first step. Theynoted that more than 70% of recorded error occurred during the second and third steps of theprocess (cutting and rotating the object). Just fewer than 30% of errors were due to the quantityidentification step in the process. For this study, analysis will be done on a virtual reality versionof the MCT using the aspects of pattern and

about the future because we will have to spend the rest of our lives there.”(CharlesFranklin Kettering, 1949)Many projects have been funded at both the local and national level for engineering education. Though theinvestigative research conducted for this paper, the authors identified 53 pre-engineering based federal and stateprojects. Of these, 15 have engineering graphics and/or design playing a role within the project. Considering this,the authors of this paper decided to include only those current and recent past projects that include engineeringgraphics in their program or project. See Table 1 for a listing of these projects.Table 1 Pre-engineering related projects that include some form of engineering graphics and/or designProject (both

As with any heuristic, there arealways exceptions and cases of interactions with other elements that cannot be predicteda priori. So, with that caveat, here are some guidelines that are both regularly violatedand, if followed, are likely to improve learning:1.

The key to theproject was seamless mobility, which is “…about creating a new world of uninterrupted accessto information, entertainment, communication, and more…The challenge with seamless mobilityis getting different technologies to work together. It’s not about one operating system or onedevice. It’s about crossing the boundaries of multiple networks, services and products”1. Asengineering graphics technology students are primarily concerned with how to effectivelycommunicate all types of information visually and graphically, this competition was an ideal way

Many educators have employed interactive multimedia inthe engineering graphics design curriculum with success in improving the mentalrotations aspect of spatial ability. Virtual reality augmented tools have also been shown toimprove spatial ability. Literature search indicated use of such tools in variety of settings.They generally allow the user to rotate models generated using CAD software9 or using aweb-based virtual reality environment11.

Sony DSR-30 DVCAM deck:The use of the Sony deck was limited within the first few months of this study. 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

the human well-being in their work.In addition to what has been mentioned, we also did assessments on students’ attitude towardergonomics. 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. In addition, we alsocollected feedback on individual exercises used in the subject

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

-study, and remediation of students in engineering graphics and otherspatially-associated fields.IntroductionAs has been described in past studies, a significant challenge that many engineering andtechnology students struggle with is the ability to “see” virtual images in three-dimensional environments [1, 2]. 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]. A usefuland applicable method of instruction and practice for engineering and technologystudents’ spatial skills has

They canbe used to define the steps of a manufacturing process. Each frame can be a snapshot of theprocess showing different viewpoints, details, or problem areas.

Because ofthe relative newness of the CGT degree nationwide, relatively few programs are accredited.Accreditation of the program is a desirable goal, to assess and maintain quality learningexperiences for students, and to produce quality graduates. Following the national trend ineducation, the CGT program intends to pursue ABET (Accreditation Board for Engineering andTechnology). Page 11.298.2Table 1.

Teaching styles which incorporateactive learning aid in self-discovery, which is not only valuable to students in the class room, butalso to faculty who must also keep up with the new technology.Susan M. Montgomery points out the learning styles of today’s students in her paper“Addressing Diverse Learning Styles Through the Use of Multimedia."

improves student success with learning the modeling package. The findings from thisstudy are presented in this paper.IntroductionIn a research study conducted at Michigan Technological University in 1997, it was shown thatthe mere act of working with 3-D computer models in a solid modeling environment does notdevelop visualization skills 1. A 1994 study by Norman 2 found that a person’s spatialvisualization skills were the most significant predictor of a person’s success in interacting with acomputer interface to perform database operations. A 1999 study by Sorby 3 found littlecorrelation between spatial abilities and the ability to work with 2-D drafting software, but foundan apparent correlation between spatial abilities and the ability to

During the Advanced CAD course,students experienced the design process using an integrated suite of Computer Aided Design(CAD), Computer Aided Engineering (CAE), and Computer Aided Manufacturing (CAM)applications for digital product definition and simulation.1 Teaching students about theintegrated suite of CATIA within the context of the design process offered a few challenges.Text books on CATIA® V5 focus on introductory level skills in the solid modeling domain.2Several tutorials provide surface modeling exercises for students.
