Find Symmetry

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
  1. From the Geometry ribbon, click the arrow next to the Cleanup tool set name and select Find Symmetry.
    The Find Symmetry dialog opens.
  2. 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.
  3. Select surfaces.
  4. Define your axis of symmetry by selecting a vector entity and a base node.
  5. 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.
  6. Click Apply.
