Discussed is a method to teach undergraduate students how to complete a conceptual design. Presents three tools to use: (1) how to use order-of-magnitude arguments to simplify problems, (2) how to derive design heuristics, and (3) how to decompose large problems into a set of small, simple problems.

This paper discusses the mechanization of mathematical functions by means of analog electronics. Five different approaches are described which demonstrate the versatility of the analog technique by using parabolic function, exponential decay technique, projectile trajectory, trigonometry, and piecewise linear approximation techniques.

Illustrates how triangular diagrams can aid in presenting some of the rather complex transient interactions that occur among gas and surface species during heterogeneous catalytic reactions. The basic equations and numerical examples are described. Classroom use of the triangular diagram is discussed. Several diagrams and graphs are provided. (YP)

Describes a three-dimensional computer aided design software package, CADKEY, for demonstrating orthographic orthodirectional projection theory to a classroom. Provides several figures for showing the demonstrations. (Author/YP)

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Demonstrates one method for finding parallel tangents to a cylinder based on geometric properties of the three dimensional representation of the cylinders. Uses rotational transformations to obtain a three dimensional view. Provides a starting point for those studying geometric methods as a lead into computer assisted drafting. (CW)

Describes an approach to teaching engineering design that involves analyzing, designing, building, and testing a simple structure. Explains the procedures for the various activities and discusses how the design concept can be incorporated into other courses. (ML)

Discusses coordinate systems, units of measure, scaling and levels as they relate to a database generated by a computer in a spatial rather than planer location. Describes geometric-oriented input, direct coordinates, transformations, annotation, editing and patterns. Stresses that hand drafting emulation is a short-sighted approach to…

Suggests a method of integrating teaching microcomputer graphics in engineering curricula without encroaching on the fundamental engineering courses. Includes examples of engineering graphics produced by commercial programs and others produced by high-level language programing in a limited credit hour segment of an educational program. (CW)

Describes the process of planning, designing and implementing a computer-assisted design laboratory to serve both a freshman engineering graphics and a sophomore engineering design course. Discusses some of the impact that this development had on other college facilities. Includes goals, testing, installation, current use, examples of assignments,…

Discusses the similarities, differences, advanced features, applications and number of users of five microcomputer computer-aided design (CAD) packages. Included are: "AutoCAD (V.2.17)"; "CADKEY (V.2.0)"; "CADVANCE (V.1.0)"; "Super MicroCAD"; and "VersaCAD Advanced (V.4.00)." Describes the…

Summarizes literature in engineering design related to constraint-based modeling. (Author/KHR)

Explains the approach taken at Colorado State University in a collegewide undergraduate computer-aided design (CAD) course. Reviews the topic areas covered, project requirements, and assesses the use of high-performance graphics devices. (ML)

Examines changes in engineering and technical graphics education through an historical perspective. Focuses on educators' view of fundamental philosophical beliefs and how the philosophical change in what and how we teach can affect the future of the profession. Discusses the need for establishing an educational philosophy. (Author/KHR)
