Abstract There were some repeatedly exposed drafting and design problems seen in senior design projects in our mechanical engineering technology (MET) program. Also our students were not able to apply the solid modeling

As results, the students' abilities to use the solid modeling CAD system for mechanical design were significantly enhanced; they became much more familiar with the requirements and standards for professional drawings; they gained good knowledge and experience in design. We feel that the concept presented in this paper is a good approach to producing graduates with the appropriate skills 1 . Development of Design knowledge and Experience Some activities were focused on the design aspect. Since these activities were performed on the CADD system, knowledge of CADD was also promoted. Design an assembly with selecting proper parts from an industrial catalog In this activity, students needed to 1. Select a proper diamond pin from the CarrLane catalog and find in the catalog Key dimensions, size tolerances and GD&T of the diamond pin Dimensional information for seating the diamond pin in an assembly Part numbers of the matching liner and lock screw 2. Find on the page of the liner and the page of the lock screw, respectively, Key dimensions, size tolerances and GD&T of the two elements 3. Determine key dimensions and tolerances of the base plate 4. Place the key dimensions and tolerances of all the parts into a spreadsheet Examine the relevant dimensions across the parts 5. Create the base part model 6. Create the assembly model
