EGR102 - Engineering Drawing 2
Credits: 4 Catalog Description: Solves drafting problems using advanced drawing techniques. Compares CAD methods and manual drafting techniques. Areas of study include projection of surfaces, secondary auxiliary views, basic tolerancing, determining classes of fits, sheet metal drafting, geometric tolerancing, threads and fasteners, and metric practices. Requires completion of formal detailed drawings demonstrating manual drawing skills and advanced problem solving and visualization skills, following ANSI standards. Two class hours, four laboratory hours. Prerequisite: EGR101. Lecture: 2 hrs. Lab: 4 hrs. Student Performance Outcomes: Upon successful completion of this course, as documented by the final practical exam and lab drawings, students will be able to: 1. Demonstrate the ability to project different surfaces (normal, inclined, oblique and curved) on at least four in class worksheets. 2. Demonstrate the ability to setup a drawing in the proper format representing a secondary auxiliary view using ANSI standards on one formal drawing assignment. 3. Demonstrate the ability to read and interpret basic tolerancing methods presented in class on at least four in class worksheets. 4. Develop a minimum of three drawings to be constructed using different sheet metal drafting methods and techniques for their solutions, i.e., parallel line method, radial line method and triangulation method. 5. State in writing the important limit dimensions (upper and lower basic hole size, and upper and lower shaft sizes) that would be calculated with the use of class of fits tables on a minimum of three problem work sheets. 6. Demonstrate the ability to read and interpret the symbols used in geometric tolerancing and dimensioning practices on at least three work sheets presented in class. 7. Demonstrate the ability to use thread charts for determining sizes of threaded objects on at least four different parts. 8. Demonstrate the ability to construct at least two formal drawings using the metric system in constructing and dimensioning the parts. 9. Complete a final practical exam documenting the ability to utilize the drawing techniques and methods of construction that were presented in course materials and information during the semester. This course objective has been identified as a student learning outcome that must be formally assessed as part of the College's Comprehensive Assessment Plan. All faculty teaching this course must collect the required data (see Assessing Student Learning Outcomes form) and submit the required analysis and documentation at the conclusion of the semester to the Office of Assessment and Special Projects.
