Program Goal and Outcomes
Program Goal: The Career Certificate program provides students with the necessary skills for entry into the field of drafting. Upon completion of the course, students will be able to create both mechanical and architectural drawings.
Upon completion of the program, students will be able to:
- Be familiar with the basic techniques used in sketching and with occupations that use drafting language
- Complete drawings using orthographic projection, points of view, and shape descriptions
- Know the techniques of lettering, and recognize the lines used in mechanical and architectural drawings as well as the representation of math operations in drafting
- Understand the use of drafting vocabulary, geometry, and instruments in the layout of drafting problems and geometric designs
- Describe size and shape using the regular views of drafting and the principal views of orthographic projection
- Work with various views, projections, tolerancing techniques, dimensions, and control frames
- Complete working drawings and become familiar with the capabilities, applications, and development of computer software drawing programs
- Prepare complete sets of structural drawings for a site plan, transit lines, and plans and profiles from survey information
- Prepare complete HVAC drawings, electrical diagrams and cable assemblies, industrial electrical schematics, and electronic block and schematic diagrams
