EL504 - Drawing Interpretation

Access Activity

Overview / Abstract:

This course covers the majority of information required to understand basic mechanical two-dimensional engineering drawings. Topics covered are:
- Basic drawing elements (formats, title block, parts list, revision block, etc.)
- Part views (multiview, auxiliary, and isometric)
- Section views
- General dimensions
- Tolerances
- Finish and welding symbols.

The course consists of nine modules, each with a quiz; most also include drawing assignments and supplementary information. As reference material, a drawing packet is included that shows five detail drawings and an assembly drawing for the parts of a Trolley Wheel. The package includes flat and round parts and a casting. Possession of the ASME Y14.5 Dimensioning and Tolerancing Standard is recommended.

This is an online, instructor-supported course, allowing you to work at your own pace and convenience.

You Will Learn To
- Describe the fundamentals of drawing interpretation
- Identify drawing elements, including part views and sections
- Describe general dimensions and tolerances
- Explain how to present surface texture, fasteners and welding
