Computer Aided Drafting

CAD 140  (3 CR)
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. Lecture 2 hours. Laboratory 2 hours. Total 4 hours per week.

CAD 161 (2 CR)
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. Laboratory 3 hours per week.

CAD 225  (3 CR)
Machine Drawing and Design

Prerequisites:  CAD 140 or EGR 115 and CAD 241 

Teaches design of basic machine elements and the analysis of linear and geometric tolerancing including the preparation of complete design and production drawings. Lecture 2 hours. Laboratory 3 hours. Total 5 hours per week.

CAD 241 (3 CR)
Parametric Solid Modeling I

Prerequisite: CAD 140

Focuses on teaching students the design of parts by parametric solid modeling. Topics include, but are not limited to, sketch profiles, geometric and dimensional constraints, 3-D features, model generation by extrusion, revolution and sweep, and the creation of 2-D drawing views that include sections, details, and auxiliary. Part I of II. Lecture 2 hours. Laboratory 2 hours. Total 4 hours per week.

CAD 242 (3 CR)
Parametric Solid Modeling II

Prerequisites: CAD 241

Focuses on teaching the design of parts by parametric solid modeling. Topics covered will include, but not be limited to, sketch profiles, geometric and dimensional constraints, 3-D features, model generation by extrusion, revolution and sweep, and the creation of 2-D drawing views that include sections, details and auxiliary. Part II of II. (Credit will not be awarded for both CAD 242 and DRF 232.) Lecture 2 hours. Laboratory 2 hours. Total 4 hours per week.

CAD 243 (3 CR)
Parametric Solid Modeling III

Prerequisites: CAD 241 and CAD 242

Focuses on teaching the software for the design of parts and assemblies by means of advanced parametric solid modeling to include advanced mechanical drafting techniques and building mechanical assemblies. Lecture 2 hours. Laboratory 2 hours. Total 4 hours per week.
