Symmetry Modeling
Symmetry modeling simplifies the creation of axis-symmetric parts and
also speeds performance for these types of parts. In this approach you
make one symmetric body, pattern the bodies to obtain the remaining geometry,
then use the Combine
feature to glue all of the bodies together. You can use multiple patterns
and combine features to create an entire model.
For instance, the example below shows the design progression of a symmetrical
part.
Begin by building the basic piece that you
pattern later. |

|
Next, add the end piece, keeping this body
separate, but adjacent. |

|
Then pattern the basic piece. |

|
Lastly, mirror the entire part, including
the end piece, and combine the bodies. |
