CAD 200: Intermediate Computer Aided Design 3 Credits

DESCRIPTION:

Students will develop familiarity with standard symbols associated with one or more application areas. Competency will be developed in advanced techniques of drafting, including complex curves, layering, and the production of three-dimensional wire models—with and without hidden lines. The students also will learn to calculate lengths and areas associated with the drawings, and will write simple programs in an appropriate high-level language to interface with the existing CAD software. Lecture: 2 hours; Laboratory: 3 hours. Prereq: CAD 100 and CAD 150 or consent of instructor.

COURSE COMPETENCIES:

Upon completion of this course the student can:

1.Demonstrate, through practice and communications, a comprehensive working knowledge of basic CAD drafting and the drafting symbols associated with one or more design applications.
2.Produce complex drawings through the process of layering, one at a time, simpler portions of the complex illustration(s).
3.Produce the complex curved lines required by certain designs, through use of the CAD techniques.
4.Use CAD equipment to calculate lengths (perimeters) and areas for any of the design features.
5.Construct three-dimensional wire models of a design(s) - isometrics, obliques, and/or perspectives- in concert with the sophistication of the CAD software and hardware available.
6.Develop wire frames into solids in two phases: first, by identifying the hidden lines of the wire frame; and second, by removing the hidden lines to reveal the solid shape.
7.Project two-dimensional orthographic and axonometric views and sections off of the three-dimensional models.
8.Write simple subprograms and link them with the CAD software to perform some CAD functions that are not presently available.
9.Document data processing developments to provide user-friendly instructions for developed programs.
