Course Description:

In this advanced drafting course, students reinforce their knowledge of engineering drawing and its applications. This course includes the theories of all types of section, detail and assembly, welding, and development drawings. Surface texture, geometric dimensioning and tolerancing (GD&T), and threaded and miscellaneous fasteners are also discussed in depth.

    3. Properly place geometric characteristic, material condition, and material boundary symbols in feature control frames.
    4. Describe methods for identifying datum surfaces, target points, areas, lines, center planes, and axes on drawings.
Evaluation Criteria/Policies:

The grade will be determined using the Delaware Tech grading system:

90 100 = A
80 89 = B
70 79 = C
0 69 = F

Students should refer to the Student Handbook for information on the Academic Standing Policy, the Academic Integrity Policy, Student Rights and Responsibilities, and other policies relevant to their academic progress.
