Comparing Mirror and Cyclic Symmetry
Here is a summary of how mirror symmetry differs from cyclic symmetry.
Mirror Symmetry
Cyclic Symmetry
Useful for symmetry problems with relatively simple geometric profiles.
Useful for symmetric problems with complex geometry.
You reduce the geometry by placing constraints along planes of reflective symmetry. Each plane, in effect, reduces the model or model segment by one half.
You reduce the geometry by finding the smallest symmetric segment and applying cuts to isolate this segment.
If you choose to use cuts to isolate the symmetric segment, the cuts must be planar.
Cuts you use to isolate the symmetric segment need not be planar.
You must explicitly define separate constraints for each unique plane of symmetry to indicate that the segment is connected to the parent model.
You define a single cyclic symmetry constraint for both cut surfaces or, in the case of shells, both cut curves. Creo Simulate interprets the constraint to mean that the model is a symmetric segment.
You can define more than one mirror symmetry constraints for a single model. The mirror symmetry planes must be parallel or orthogonal to each other.
You can define only one cyclic symmetry constraint for a single model.
