Graphics and modelling

• What is the primary purpose of sketches in design?

  To help visualize products/ideas and examine problem areas
• What are some common types of sketches used in design?

  • Rough 2D/3D sketches
  • Orthographic sketches
  • Oblique sketches
  • 1 Point Perspective
  • 2 Point Perspective
  • Isometric sketches
  • Rendered Illustrations
• What types of drawings are used to demonstrate plans for manufacture?

  • Exploded Drawing
  • Sectional Drawing
  • Scale Drawing
  • Working Drawing
  • CAD Drawing
• Why is it important to consider the purpose of a model before modeling begins?

  To ensure the model effectively serves its intended function
• What are some types of modeling techniques available?

  • Physical modeling
  • Digital modeling
  • Sketch Models
  • Block Models
  • 3D CAD Models
  • Rapid Prototyping
  • Scale Models
  • Prototypes
• What aspects can modeling help test and find information about?

  Materials, functions, ergonomics, safety, aesthetics
• What are some materials commonly used in modeling?

  • Pipe Cleaners
  • Clay
  • Card/Paper
  • Balsa Wood
  • MDF
  • Wire
  • Sheet Plastic
  • Styrofoam
• What are the characteristics of Sketch Models?

  They are quick, easy, inexpensive, and help visualize shape and form
• How are Block Models created and what is their purpose?

  They are made from a block of material to replicate appearance without internal components
• What is the purpose of 3D CAD Models?

  To reflect aesthetics and test safety/sizes with low model costs
• What is Rapid Prototyping?

  It involves printing a 3D CAD model to provide a physical model
• What is a Scale Model and its purpose?

  It is a physical model made to full-scale or a portion of the actual size to determine final sizes and ergonomics
• What defines a Prototype in design?

  A physical full-scale working version of the final design using materials as close to the final product as possible
• Why are prototypes considered expensive to make?

  Because they function exactly as the final product would and require high-quality materials
