Enables you to create a symmetrical copy of hierarchies according to an axis plane.
Duplicate – Lets you pick a branch as the source branch. The tool duplicates the branch and mirrors its nodes on the new branch.
Reshape – Lets you pick an existing branch as the destination (rather than have the tool create it). Geometries are not mirrored for this option.
Mirror provides three mirroring planes under world space. This option specifies the plane to use for later mirror operations: XY, YZ or XZ mirroring plane.
Turn on to merge the source and duplicate subdivision bodies when symmetrical copies are made. For best results, ensure the source object is on the symmetry plane as the tool merges the CVs that are aligned to the symmetry plane.
