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)

Explanations of geometric dimensioning symbols are provided to assist in the comprehension of the implied basic sentence structure of modern geometric dimensioning and tolerance. The proper identification and interpretation of the substantive language within several exemplary engineering drawings, otherwise called feature control frames, is…

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)

Studies the effectiveness of adding coordinate axes to mental rotations tasks. Assesses the effect of the coordinate axes, the effect of pretest sensitization, and interaction between the pretest and posttest conditions. (Author/CCM)

Argues for a legitimate role of manually expressed engineering graphics within engineering education as a needed support for computer-assisted drafting work. Discusses what and how students should learn as well as trends in engineering graphics education. Compares and contrasts manual and computer drafting methods. (CW)

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)

Reports on the development of a new CAD/CAM laboratory experience for an Engineering Design Graphics (EDG) course. The EDG curriculum included freehand sketching, introduction to Computer-Aided Design and Drafting (CADD), and emphasized 3-D solid modeling. Reviews the project and reports on the testing of the new laboratory components which were…

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)

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)

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)
