Benefits and Description
Use Mirror to mirror a selected set of geometry about a planar reference and reintersect the mirror with the remaining geometry. The resulting feature contains all the parameters and references for the Mirror operation so editing is possible. Connecting rounds are automatically rebuilt. After you mirror the geometry, the relationship is maintained. Any moves applied to the original can be propagated to the mirrored geometry.
