To Create a New Part by Copying the Geometry from a Body
When you copy a body to create a new part, the new part contains a Copy Geometry feature that also copies the parameters and properties of the original body. Because of this, you might need to edit the definition of the Copy Geometry feature in order to perform some actions in the new part.
