Balancing Research and Professional Development with Engineering Graphics Instruction.
Peer reviewed Peer reviewed
DeJong, P. S.; Shahan, J. C. – Engineering Design Graphics Journal, 1991
An investigation of alternative methods of managing lower division graphics courses is described. Nonexam grading time was reduced to nearly zero, creating time for professional growth, proposal development, and meaningful research. Grade profiles and attitudes of students taking the altered course are discussed. (KR)

2-D and 3-D CAD: Complements to Visualization.
Peer reviewed Peer reviewed
Zsombor-Murray, P. J. – Engineering Design Graphics Journal, 1990
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.…

3-D Solid Modeling: Making the Modeling-to-Drawing Interface Seamless.
Peer reviewed Peer reviewed
Ross, William A. – Engineering Design Graphics Journal, 1991
An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Representation of Projection and Coordinate Systems in Engineering Graphics.
Peer reviewed Peer reviewed
Ross, William A. – Engineering Design Graphics Journal, 1990
The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

Multiple CubicBezier Curves.
Peer reviewed Peer reviewed
Khonsari, Michael M.; Horn, Douglas – Engineering Design Graphics Journal, 1990
An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

Formulae for Numerically Determining Line of Intersection and Dihedral Angle between Two Planes.
Peer reviewed Peer reviewed
Chen, Daniel M. – Engineering Design Graphics Journal, 1990
Presented is a proposed formula for determining the bearing angle and the slope angle for the line of intersection using the strike and dip angles of two given plane segments. Included is the development of the formula and three example problems. (KR)

Choosing a Graphics Software Package for Educational Software Development: A Comparison of PHIGS and HOOPS.
Peer reviewed Peer reviewed
Vance, Judy M.; Jenison, Rollie D. – Engineering Design Graphics Journal, 1990
Two graphics interface packages, PHIGS and HOOPS, are examined. A comparison of the two packages is made in light of the Iowa State University College of Engineering's need for educational software. Conclusions based on programing experience using both PHIGS and HOOPS are presented. (KR)
