Credit Hours: 2.00

Objectives:

1. Using the material presented on engineering assembly drawings, read and interpret working instructions for assembly drawings.
2. Using the material presented on engineering detail drawings, read and interpret working instructions for detail drawings.
3. Using the material presented on engineering casting drawings, read and interpret working instructions for casting drawings.

Outcome 2: Upon completion of this course, the learner will be able to describe engineering drawing sectioning including, full sections, half sections, revolved sections, aligned sections, offset sections, removed sections, broken out sections, and partial sections.

Objectives:

1. Using the material presented on engineering drawing sectioning, draw 3rd angle orthographic projection of full and half sections.
2. Using the material presented on engineering drawing sectioning, draw 3rd angle orthographic projection of revolved sections, aligned sections and offset section.
3. Using the material presented on engineering drawing sectioning, draw 3rd angle orthographic projection of removed sections, broken out sections and partial sections.

Outcome 3: Upon completion of this course, the learner will be able to describe the process of reading and interpreting engineering drawings of assemblies, details and castings for manufacturing and assembly of components.

Objectives:

1. Using the material presented on engineering assembly drawings, read and interpret assembly drawings for shape, features of size, location dimensioning and tolerancing.
2. Using the material presented on engineering detail drawings, read and interpret detail drawings for shape, features of size, location dimensioning and tolerancing.
3. Using the material presented on engineering casting drawings, read and interpret casting drawings for shape, features of size, location dimensioning and tolerancing.
