Upon successful completion students should be able to:
1. Skillfully manipulate data from the system’s CPU, hard drive and USB drive data storage
devices.
2. Use appropriate knowledge and skills when using a computer during the development of
technical mechanical drawings.
3. Create, store, retrieve, and modify drawings using attributes following industry standards.

Drafting Fundamentals is designed to acquaint the student with a fundamental understanding of drawing techniques. Emphasis will be placed on the sketching techniques, lettering, orthographic projection, auxiliaries, sections, and pictorials. 

Evaluation procedures and grading will be discussed on the first day of class. Units of instruction begin with a lecture presentation followed by lab application, which may include individual instruction. Lab drawing assignments, exams and quizzes, and projects may be used to assess outcomes.
