About Mirroring Geometry
Use the Mirror Geometry feature to mirror selected geometry about a plane. A copy of the original geometry is mirrored in a new location and attached to the same geometry or quilt. When the geometry selection includes or is attached with round or chamfer geometry, the round or chamfer geometry is created in the new location.
You can clear the Attach mirrored geometry and the Create round/chamfer geometry check boxes to prevent failure of the Mirror Geometry feature.
When you create the mirror geometry feature in Creo Flexible Modeling, it is automatically recognized as symmetry. All subsequent work performed in Creo Flexible Modeling on the original geometry can be propagated to the mirrored geometry as well.
