Goals

  1. The primary goal of this exercise is to create 3-D model that shows the spatial relationship between a worker of a given size and a workstation of a given size (see Fig 1).
  2. A secondary goal is to familiarize you with the AutoCAD features and controls for constructing this and similar models.
  3. This exercise will use height data from the National Health Survey2, and link length data from Drills and Contini (1966)3 to create a model that can be used to explore the spatial relationship between a worker of a given size and a work bench of a given size.

  4. Workplace and worker parameters for this exercise see: Reach Limits

  • Iinformation for creating your model:

    Bench:

    • Width: 2.0m
    • Depth: 1.0m
    • Height: 0.9m
    • Top thickness: 0.05m
    • Legs: 0.1m x 0.1m
    Worker (5%female height2 and average proportions3
    • Stature: 1.504m
    • Floor-Shoulder: 1.230m
    • Distance between shoulders ÷2: 0.194m
    • Arm+Forearm+Hand: 0.663m
    • Floor-Hip: 0.797m
    • Distance between hips ÷2: 0.144m
      Location/position:
    • Facing Bench
    • Center on long side
    • Distance away from edge: 0.10m
