COURSE DESCRIPTION

Applies principles of orthographic projection and multi-view drawings. Teaches descriptive geometry including relationships of points, lines, planes, and solids. Introduces sectioning, dimensioning, and computer graphic techniques. Lecture 1 hour. Laboratory 3 hours. Total 4 hours per week.

GENERAL COURSE PURPOSE

Engineering graphics is the language that is used universally by engineers to describe the size and shape of structures and mechanisms. The course is intended to make the student able to understand and use that language. The student will acquire skills in manual graphics as well as an acquaintanceship with the fundamentals of computer graphics leading to later computer-aided-design (CAD) work, if necessary. She/he will be able to read drawings, but not be a professional draftsman.

ENTRY LEVEL COMPETENCIES

Proficiency in plane Euclidian geometry, acquired in high school.

COURSE OBJECTIVES

Upon completion of this course, the student should be able to:

A.  acquire the basic skills of lettering and sketching

B.  obtain the ability to conceptualize solids in three dimensions and represent such solids in two-dimensional displays, both manually and via microcomputer using simple CAD software

C. learn basic skills in descriptive geometry as applied to the graphical solution of engineering problems

D.  develop good study habits and an appreciation of the standards of accuracy, timeliness, and quality required in the engineering profession
