CAD 140 - Technical Drawing (3 CR.)

Course Description

Enhances the principles learned that are related directly to the field of drafting and design. Gives a more in- depth exposure to detail and working drawings, dimensioning, tolerancing and conventional drafting practices. Teaches CAD modeling, may include parametric modeling. Lecture - 2 hours. Laboratory - 2 hours. Total - 4 hours per week.

General Course Purpose

To develop skills in the use of various drafting techniques and the use of various media in both traditional and computer aided drafting.
