Catalog Course Description

A basic course for pre-engineering, pre-architecture students, and other students who have no previous Computer Aided Design (CAD) and mechanical drawing experience. 36 lecture hours, 72 lab hours.

Course Objectives

  • Demonstrate basic understanding of Computer Aided Design (CAD) and mechanical drawing practices. These include line types, text, hand lettering, dimensioning, sections, geometric constructs and CAD model and paper space.
  • Use and care for the various types of drafting equipment. These include parallel bar, T square, triangles, scales, and other equipment.
  • Use Orthographic projection, geometric construction, lettering, sections, pictorials and dimensioning
  • Compose working drawings which show the comprehension of orthographic projection, geometric construction, lettering, and dimensioning.
  • Illustrate the basic concepts of mechanical drawing practices, and translate the concepts to drawings in CAD.
