  17. 17. Draw three views of the following components in first angle projection. Show hidden detail when necessary. Use A4 paper, and give drawing title on each drawing. All dimensions are in (mm).
  18. 18. Auxiliary View An auxiliary view is an orthographic view taken in such a manner that the lines of sight are not parallel to the principal projection planes (frontal, horizontal, or profile). There are an infinite number of possible auxiliary views of any given object.
