Overview of Computer Aided Design (CAD)

Dec 11, 2024

Introduction to CAD

What is CAD?

  • CAD stands for Computer Aided Drawing.
  • Used to draw on a computer, which aids in manufacturing.
  • Utilized in the construction of everything built in the last 30-40 years.

Professions Using CAD

Structural Engineers

  • Use CAD to evaluate the strength of buildings and bridges.
  • Test materials for strength before construction.

Biomedical Engineers

  • Develop medical devices like ventilators, CAT scan machines, and prosthetics.
  • Include hospital furniture, pacemakers, and artificial heart valves.

Electrical Engineers

  • Design components for computers used in phones, cars, refrigerators, etc.
  • Design circuits with wires and components for installation in various devices.

Aerospace Engineers

  • Design aircraft and spacecraft components.
  • Use CAD to simulate air flow over wings and assess reactions to conditions.
  • NASA uses CAD for designing International Space Station components.

Visual Effects Artists

  • Use CGI to create images for movies, video games, and TV.
  • Combine live-action with CGI for action sequences in movies.

Industrial Designers

  • Design product aesthetics and functionality, e.g., shampoo bottles.

Interior Designers

  • Layout building spaces using CAD.
  • Show potential designs to clients before material purchase.

Furniture Designers

  • Develop plans for items like kitchen cabinets and TV stands.
  • Use CAD to ensure accuracy for manufacturing.

Architects

  • Use CAD to visualize and design buildings from homes to skyscrapers.

Applications of CAD

Design and Manufacturing

  • CAD allows for precise design, resulting in accurate manufacturing.
  • Example: design and build a door, a TV stand, or a deck using CAD plans.

Project Example

  • Creation of a fireplace mantle with hidden features using CAD.
  • CAD drawing used to plan pieces for cutting and assembly.

3D Printing

  • Design objects in CAD, then print using a 3D printer.
  • Example: redesign a broken microphone mount and print a new one.
  • Create protective face shields for medical workers using CAD and 3D printing.

Conclusion

  • CAD spans a broad array of fields from engineering to design and entertainment.
  • Encouraged to explore and answer questions about CAD on a Google Doc.

  • Remember, CAD skills are used daily in various engineering fields.
  • Engage with CAD projects to apply what you've learned.
