This course will present the main concepts of computer aided design: solid modeling, assembly design, engineering drawing conventions, and dimensioning and tolerance specification. Students will design a mechanical device from concept through detailed drawings to prototype fabrication. This is a "hands-on" course, all concepts will be introduced in an interactive lab/lecture environment.

Students are expected to attend all class meetings. Graded class activities will be held everyday. Work not completed in class will be graded according to the following policy:

  1. If you have an unexcused absence (i.e., not pre-approved, documented illness, or documented university activity), then you can complete the posted exercises for half credit any time prior to the next class meeting.
  2. If you have an excused absence (i.e., it has been pre-approved, or resulted from a documented illness, or documented university activity), then you can complete the posted exercises for full credit any time prior to the next class meeting.
  3. If you attend class but can not complete the exercise during the class period, you can complete the exercises for full credit any time prior to the next class meeting, (i.e. this is homework).

In all cases, you are responsible for completing the exercises outside of class on your own, and you must show me the completed exercises prior-to or at the start of the next class period.

University of North Carolina at Asheville is committed to making courses, programs and activities accessible to persons with documented disabilities. Students requiring reasonable accommodations must register with the Office of Academic Accessibility by providing supporting documentation. All information provided will remain confidential.

  1. Students understand the engineering design process and the role that drawings play in that process.
  2. Students can create 3D solid models of mechanical components using CAD software.
  3. Students can create mechanical assemblies using CAD software.
  4. Students can use motion simulation and animation to analyze assembly interactions.
  5. Students can prepare engineering drawings from 3D solid models.
  6. Students understand engineering drawing conventions.
  7. Students understand drawing tolerances and the role that they play in manufacturing and inspection.
  8. Students demonstrate an understanding of selected manufacturing processes including 3D printing.

Description Number Individual Points Net Points
Lab Exercises* (approx.) 15 10 (approx.) 150
1 100 100
Totals 250 points

*Lab Exercises will be graded on the +/- scale, where + indicates satisfactory, and - indicates needs improvement.

Letter grades are assigned based on the percentage of available points obtained by a student. 100% to 90% guarantees some sort of A, 89% to 80% guarantees some sort of B, and so on. Plus and minus grades will be used for this course, as shown in the table below. The instructor reserves the option of relaxing the cut-offs for a letter grade in special circumstances.

Score ≥ 92 & Score < 100A
Score ≥ 90 & Score < 92A-
Score ≥ 87 & Score < 90B+
Score ≥ 82 & Score < 87B
Score ≥ 80 & Score < 82B-
Score ≥ 77 & Score < 80C+
Score ≥ 72 & Score < 77C
Score ≥ 69 & Score < 72C-
Score ≥ 65 & Score < 69D+
Score ≥ 60 & Score < 65D
Score ≥ 57 & Score < 60D-
Score < 57F


Students enrolled in this course can install SolidWorks Education Edition on their Windows computers. These instructions for installing SolidWorks and a VPN to manage the license were developed by Gabe Earley.

Here's another great set of instructions developed by Brandon Zschokke.

Unfortunately, there have been problems with the install on Windows that block the use of equations. Here is a description of a fix for that problem provided by Mason Logan.
