Proposes a simple approach for including exercises into the freshman level classroom to help first and second semester students approach and solve problems in novel and inventive ways. (Author/CCM)

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.

Introduces a project for planning a modern engineering design curriculum for the 21st century in the field of engineering design graphics. (Author/CCM)

A graphical illustration is presented indicating how the mean proportional (geometric mean), once established for one set of conditions of a geometric identity, can be used to generate other sets of conditions for the same identity. Exemplified is the application of this principle in developing graphical solutions to engineering problems. (JJK)

Describes group design techniques used within the engineering design graphics sequence at Western Washington University. Engineering and design philosophies such as concurrent engineering place an emphasis on group collaboration for the solving of design problems. (Author/DDR)

Described is a computer algorithm for obtaining the coordinates of vertices, chord factors, and dihedral angles for plotting orthographic and axonometric projections, and for tabulating chord lengths and dihedral angles. (Author)

Described are improvements for the computer efficiency of the two midpoint scan-conversion algorithms used to draw ellipses. Included are computer programs written in C programing language. (JJK)

Uses Shneiderman's Object-Action Interface model along with the engineering design process as a framework for understanding software interface elements. Provides an educational framework from which instructional materials can be developed. (Author/CCM)

Reports the results of a survey that collected information on the focus areas instructors feel are important when grading different types of drawings. Also explores the reasons given for the grading criteria. (DDR)

Illustrates the use of a course focused on developing 3-D spatial skills at Michigan Technological University. Provides data to support the recommendation that some students take the spatial skills course before enrolling in the regular engineering graphics courses. (DDR)

Answers several questions regarding background information on research in spatial skills. Describes strategies that graphics educators can adopt to develop these skills in students. (Author/CCM)

Describes experiences for engineering students to develop spatial awareness and reasoning capability. Describes geometric modeling, basic geometric concepts, operations, surface modeling, and conclusions. (YP)

Describes new geometric computer models used in contemporary computer-aided design (CAD) software including wire frame, surface, solid, and parametric models. Reviews their use in engineering design and discusses the impact of these new technologies on the engineering design graphics curriculum. (Author/CCM)

Describes the various phases of software development and shows how it can be used in an engineering graphics course. Includes demonstration exercises, practice exercises, code development and software as they have been used at Clemson University. (CW)

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…
