Mirror options

> Mirror Type

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 Across

Mirror provides three mirroring planes under world space. This option specifies the plane to use for later mirror operations.

xy mirroring planes

yz mirroring planes

xz mirroring planes
