Find symmetrical surfaces or compare selected surface sets for symmetry. You can
reorganize found symmetric surfaces into separate components or delete one subset of a pair
of symmetric surface sets.
This can be helpful with highly symmetrical components,
because you can then perform geometry cleanup on only one half, mesh it, and then mirror
the mesh instead of having to clean up the entire component prior to meshing

From the Geometry ribbon, click the arrow next to the
Cleanup tool set name and select
Find Symmetry.
The Find Symmetry dialog opens.

Select an action.
 Find symmetry
 Locate surfaces within a single component that are mirror images of
one another across a plane of symmetry that you specify.
 Compare
 Find symmetric surfaces among different components that you
select.

Select surfaces.

Define your axis of symmetry by selecting a vector entity and a base
node.

Select a result.
 Reorganize
 Organize the symmetric surfaces into new, separate component.
 Delete Positive
 Delete the symmetric surfaces on the positive side of the symmetry
axis. Used when finding symmetry.
 Delete Negative
 Delete the symmetric surfaces on the negative side of the symmetry
axis. Used when finding symmetry.
 Delete First
 Delete the symmetric surfaces from the first set of selected
surfaces. Used when comparing symmetry.
 Delete Second
 Delete the symmetric surfaces from the second set of selected
surfaces. Used when comparing symmetry.
