Course Description

Introduces skills needed to produce 2-D mechanical drawings using hand sketching techniques on grid paper. Includes orthographic projection, lettering, auxiliary views, sections and pictorial drawings. Covers dimensioning basics. Audit available.

Intended Outcomes for the course

Upon successful completion students should be able to:

1. Apply hand sketching skills in the development of technical mechanical drawings.
2. Apply industry standards in the development of technical mechanical drawings.
3. Incorporate and articulate appropriate specific industry vocabulary within the technical
mechanical drawings.

Course Activities and Design

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.

Outcome Assessment Strategies

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.
