Course Number and Title: EDT 252 Engineering Design III
This advanced course provides an overview of the rules, standards, and practices in designing, drawing, dimensioning, and tolerancing mechanical components and assemblies. The use of computer-aided design (CAD), engineering design standards, product end-use requirements, manufacturability considerations, and vendor-supplied specifications in the design process are covered. Original designs for complex functional mechanical components and systems are developed, dimensioned, and drawn to acceptable professional standards.

- Generate a complete and accurate engineering title block.
- Correctly identify, draw, and interpret common weld symbols and explain their implications relative to weld fabrication.
- Design a simple mechanical assembly for fabrication as a weldment.
- Correctly use orthographic, auxiliary, sectional, and isometric views with all required dimensions, tolerances, and notes to fully define a complex mechanical component for manufacture.
- Use conventional and geometric tolerancing techniques to accurately define mechanical designs and assembly designs for manufacture.
- Accurately read and create limit dimensions for common mechanical geometries.
- Describe and apply nominal sizes and stock sizes in the design of complex mechanical components.
- Dimension mating parts and assemblies using limit dimensions, unilateral tolerances, and bilateral tolerances.

- Perform a basic stack tolerance analysis on a mechanical component or assembly.
- Use engineering design standards, product end-use requirements, manufacturability considerations, and vendor-supplied specifications in the design process.
- Use engineering documentation procedures to produce and maintain an accurate and up-to-date set of engineering drawings and specifications.
- Produce a complete set of drawings, including individual detail drawings, three-dimensional (3D) assembly drawings, isometric or 3D exploded views, parts lists, design constraints, and bill of materials (BOM) for a detailed mechanical assembly.
- Generate and explain the rationale behind a part numbering system for a mechanical assembly and/or product line.
- Document an engineering change notification for a mechanical design, and explain the implications of keeping such a system up to date in an engineering and/or manufacturing operation.
Students must demonstrate proficiency on all CCPOs at a minimal 75 percent level to successfully complete the course. The grade will be determined using the Delaware Tech grading system:
