Engr 105: Engineering Graphics
Course Description
Freehand and computer aided drawing in pictorial and orthographic projection; section and auxiliary views; descriptive geometry; graphical presentation of data; scales, dimensioning, and measurements.
Course Scope
The course provides an overview of engineering graphical communication and the use of SolidWorks as a computer design tool for producing working drawings. The topics covered encompass orthographic projection, section and auxiliary views, tolerances and annotations, and thread conventions. Through a series of SolidWorks related tutorials and assignments, students learn how to create solid models of parts and assemblies. The course also introduces students to 3D printing of solid objects from CAD models.
Course Objectives
All students who participate in Engr 105 by the end of the course should demonstrate the ability to:
1. Understand the concepts of creating technical working drawings in traditional and electronic form.
2. Produce working drawings of designed parts that meet defined standards and conventions.
3. Distinguish between standard orthographic views of parts in first and third angle projections.
4. Produce sectional, auxiliary and detail views for a part or assembly.
5. Apply dimensions and tolerances to parts and assemblies in drawings.
6. Use drafting tools to manually produce working drawings.
7. Create solid models of parts/ assemblies by using the SolidWorks software package.
8. Interpret working drawings and communicate product design.

Evaluation Procedures
Six assignments will be assigned in total. Three assignments involve in-class parts or assemblies modeling with SolidWorks, whereas three of the assignments are to be done as homework and involve manual sketching of orthographic projections of parts. The course project involves modeling an assembly system in SolidWorks, and creating a working drawings package for the system. There is one mid-semester examination, and one final examination.
