Computer Aided Design and Drafting (CADD) programs are used to teach drafting at an Indiana high school. The school system's maintenance department shared use of the software and equipment to produce original drawings of school buildings. (MLF)

This report reviews eight IBM-compatible software packages that are available to secondary schools to teach computer-aided drafting (CAD). Software packages to be considered were selected following reviews of CAD periodicals, computers in education periodicals, advertisements, and recommendations of teachers. The packages were then rated by…

Presents a paper-folding method to develop a class repertoire of construction methods for the ellipse, hyperbola, and parabola using straws, rulers, dental floss, paper circles, and other household items. Uses the Geometer's Sketchpad software to complement the paper-folding process. (MKR)

Discusses the distinction between drawing and constructing in dynamic geometry environments. (MKR)

Advances four propositions in an effort to provide a frame of reference for a new generation of interactive engineering graphics scholars. Suggests the integration of traditional engineering graphics with new production tools such as computer-aided design drafting. Proposes that graphics problem-solving educational opportunities be maximized. (CW)

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)

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)

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…
