MEC 121 - Computer-Assisted Design (CAD) Applications

 
Description
This course is a continuation of the study of computer generated graphics. Students develop advanced skills in computer-based drawing by creating working drawings for engineering applications with an emphasis on 3-dimensional (3D) design and modeling. These drawings include orthographic projection concepts, section views, tolerancing and dimensioning, notes, schedules and symbols lists. Students create drawings using computer assisted design (CAD) software, including AutoCAD and Solidworks.

1. Construct orthographic drawings using different layers, colors, line types and line weights specified by the American National Standards Institute (ANSI) standards.
2. Select plotting devices and modify plotting device configurations to produce hard copies of completed CAD drawings.
3. Create precision drawings with object snap modes and advanced drawing commands.
4. Use the AREA command to calculate the area of an object by adding and subtracting objects.
5. List data related to a single point, an object, a group of objects or an entire drawing.
6. Create text and dimension styles.
7. Use dimensioning commands to dimension a drawing to accepted drafting standards.
8. Describe the purpose for and proper use of layouts.
9. Manipulate layouts.
10. Prepare layouts for plotting.
