This intermediate course provides an overview of the rules, standards, and practices used to design, draw, dimension, and tolerance simple mechanical components and assemblies. The use of computer-aided design (CAD), engineering design standards, and vendor-supplied specifications in the design process are covered. Orthographic and detailed assembly drawings are developed to scale, dimensioned, and drawn to acceptable professional standards.

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.
