THEMES, CONCEPTS, AND ISSUES:
 

  • Industrial, manufacturing, mechanical and other drafting technology students must be able to visualize and graphically reproduce complex layouts to succeed in subsequent drafting and design courses.
  • Drafting Designers and Engineers need to be able to communicate with each other, and with manufacturing and construction personnel, using graphical representations of physical objects.
  • AutoCAD design software is widely used in the drafting technology professions.
  • Many drafting graduates enter the workplace by performing computerized graphics manipulations.

COMPETENCIES AND SKILLS:
The student will be able to:

  • Communicate effectively using computerized graphical techniques.
  • Demonstrate intermediate to advanced competency using AutoCAD graphics software.
  • Create solid models for use in subsequent drafting courses or within industry.
  • Create a portfolio of AutoCAD drawings to demonstrate their abilities.
