Learning Objectives

Drawings are essential communication tools for engineers. They are used for conveying ideas, designs and details of work to others. Engineering students must be able to visualize three dimensional objects and present them on paper in order to be able to communicate with others during their study period and throughout their careers. This course emphasizes visualization and presentation of three dimensional objects as well.

Outcomes

Introduce students to the basics of descriptive geometry and engineering drawing. By the end of the course, students should be able to:
  • Analyze and visualize three dimensional objects.
  • Make good quality sketches to convey ideas to others.
  • High quality precise drawings using instruments

Course Outline

The course in Engineering Drawing includes introduction to drawing tools, projection of points, lines, planes and solids. Orthographic projection techniques, 1st and 3rd angleprojection and Axonometric projections.

Evaluation Method: There will be at least 4 quizzes, one Mid Semester Exam, and One Final Exam. In addition, there will be at least 11 detailed Lab assignments to be completed within specified due dates/timings. Grading will be relative.
