In this course, students focus on advanced drafting practices. Topics explored include the study of primary and secondary auxiliary views as well as an in-depth study of all American National Standards Institute/American Society of Mechanical Engineers (ANSI/ASME) dimensioning practices along with tolerances, fits, and surface texture. Threaded and miscellaneous fasteners are also discussed.

- Apply angular, callout, overall, limited length, and area dimensions.
- Dimension and recognize standard symbols for curved features.
- Define and dimension chamfers, threads, drills, tapers, knurling, and keyways.
- Apply tabular, arrowless, rectangular coordinate, and polar dimensioning.
- Apply required fits and tolerances to various shop drawings.
- Analyze part features in terms of integral geometric shapes to facilitate concise dimensioning within prescribed tolerances.
- Solve tolerance problems, including limits and fits.
- Prepare completely dimensioned multi-view drawings with tolerances.
- Interpret and specify surface textures and related notes to different engineering drawings.
- Recognize finish marks, general symbols and notes, and ANSI basic surface texture symbols.
- Identify the differences of surface roughness on real mechanical pieces.
- Accurately draw surface finish symbols and related notes on drawings.
The grade will be determined using the Delaware Tech grading system:
| 90 | – | 100 | = | A |
|---|---|---|---|---|
| 80 | – | 89 | = | B |
| 70 | – | 79 | = | C |
| 0 | – | 69 | = | F |
