CAD 140 - Technical Drawing
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. (Credit will not be awarded for both CAD 140 and DRF 140.)
Lecture 2 hours. Laboratory 2 hours. Total 4 hours per week.
3 credits
CAD 161 - Blueprint Reading I
Teaches the application of basic principles, visualization, orthographic projection, detail of drafting shop processes and terminology, assembly drawings and exploded views. Considers dimensioning, changes and corrections, classes of fits, tolerances and allowances, sections and convention in blueprint reading. (Credit will not be awarded for both CAD 161 and DRF 161.)
Lecture 0 -1 hours. Laboratory 3 hours. Total 3-4 hours per week.
1-2 credits
CAD 199 - Supervised Study In (discipline)
Assigns problems for independent study outside the normal classroom setting under the guidance and direction of an instructor. Incorporates prior experience and instruction in the discipline.
Variable hours per week.
1-5 credits
CAD 225 - Machine Drawing and Design
Teaches design of basic machine elements and the analysis of linear and geometric tolerancing including the preparation of complete design and production drawings. (Credit will not be awarded for both CAD 225 and DRF 225.)
Lecture 2 hours. Laboratory 3 hours. Total 5 hours per week.
