TDSN 250 - Introduction to CAD

4 Credit (2 lecture, 2 lab) 4 Contact Hours [Instructor/counselor/advisor permission]

This course is an introduction to computer aided drafting and design. CAD software is used to create three-dimensional models of solid objects. Part models can then be used in assembly models. Traditional CAD drawings are also produced from the part models. There is an introduction to computer aided manufacturing where programs are produced to actually make a part.
OFFERED: fall semesters
