Topics
• Creating orthographic projection• Auxiliary view
Creating an Orthographic Projection
• Choose a front view. – Which view shows the most about the object?
C
Creating an Orthographic Projection
• Decide how many views are needed.– How many and which views?2FrontTop
For procedural reasons, we will continue this example by drawing all 3 standard views.
Creating an Orthographic Projection• Draw the
visible features of the front view.
Creating an Orthographic Projection• Draw
projectors off of the front view.
Creating an Orthographic Projection
• Draw the top view.
Creating an Orthographic Projection• Project back
to the front view.
Creating an Orthographic Projection• Draw a 45
projector off the front view.
Creating an Orthographic Projection• Draw
projectors over to the 45 line and down.
Creating an Orthographic Projection• Draw the
right side view.
Creating an Orthographic Projection• Project back
if needed.
Creating an Orthographic Projection• Draw
centerlines where necessary.

Completed Drawing
Exercise
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).
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.
