Thenew generation of constraint-based modelers provides a dynamic, 3-D environment whereboth size and geometric form constraints can be demonstrated and explored directly. Thispaper will present examples of exercises that can be used in an engineering design graphicscourse to demonstrate both the concepts of GD&T and good design practice. The examplesinclude: 1) The relationship of datums in the 3-D modeling environment to the theoreticaldatums used in GD&T. 2) The transformation of implicit feature constraints in the 3-Dmodel to explicit GD&T constraints. 3) How constraint modification in the model can beused to explore maximum and least

Preliminary findings indicated that:• On as scale of 1 to 4, over 90 percent of the items were rated at the highest level (4).• The correlation between related items intended to measure the same constructs were difficult to interpret given the low variation of ratings, but were generally in the expected direction.• Students were asked to distribute a hundred points among the members of the group as a measure of each individual’s contribution to the

ABET; the AIChE Program Criteria inEC2000 require a working knowledge of the safety aspects of chemical processes.There are three ways of incorporating chemical process safety into the chemical engineeringcurriculum: (1) a course or courses devoted to process safety, (2) integration of chemicalprocess safety into existing courses and (3) a combination of the two approaches.Having a separate course in chemical process safety puts process safety in a prominentposition in the curriculum, forces the students to focus on process safety, and is the best way todeal with certain safety topics such as toxicology, industrial hygiene, dispersion models anddesign of relief systems. However, the students may compartmentalize safety and treat it as atopic

For instance, the one-hourlecture may be too short to solve student’s problems or to answer student’s questions.

IntroductionDesigning and design theories, methodologies and methods have been under intensiveinvestigation since about 1960 (compare chapter 3 in 1). In these investigations, several distincttrends can be found.One, the artistic trend, claims that designing needs creativity (and only creativity?), thatcreativity is an inborn trait of particular humans, and that inspiration comes from an unknownsource. In this way, the designer is unique, talented and privileged. Designing, in the extreme,cannot be taught or learned. Only a
