Basic Drafting Skills
• Sketching and Freehand Drawing
o Sketching
• Basic Manual Drafting Tools and Procedures
o Drafting Equipment
o Drafting Techniques
o Basic Geometric Construction
o Lettering
• Multi-view Drawings
o Orthographic Projection
• Basic Dimensioning
o Dimensioning and Notes
• Sectional and Auxiliary Views
o Sectional Views and Revolutions
o Auxiliary Views
• Pictorials and Working Drawings
o Pictorials
o Working Drawings
• Introduction to CAD
o Computer-Aided Drafting and Design
o AUTOCAD and/or Sketch-Up
• The Engineering Design Process
o Identify the need or problem
o Research the need or problem
• Examine current state of the issue and current solutions
• Explore other options via the internet, library, interviews, etc.
o Develop possible solution(s)
• Brainstorm possible solutions
• Draw on mathematics and science
• Articulate the possible solutions in two and three dimensions
• Refine the possible solutions
o Select the best possible solution(s)
• Determine which solution(s) best meet(s) the original requirements
o Construct a prototype
• Model the selected solution(s) in two and three dimensions
o Test and evaluate the solution(s)
• Does it work?
• Does it meet the original design constraints?
o Communicate the solution(s)
• Make an engineering presentation that includes a discussion of how the solution(s) best meet(s) the needs of the initial problem, opportunity, or need
• Discuss societal impact and tradeoffs of the solution(s)
o Redesign
• Overhaul the solution(s) based on information gathered during the tests and presentation
The Engineering Design Process will be learned and practiced through several engineering design challenges done in class. Examples: The Sailboat Design Challenge, The Ramp Climb Challenge
