Object Edit > Symmetric Modeling
 
 
 

Makes the selected geometry symmetric, and lets you modify the controls (CVs, edit points, blend points) on one side, while the corresponding controls on the symmetric half update automatically to maintain the symmetry.

The symmetry plane is defined by the default symmetry plane for the layer the curve or surface belongs to (Y=0 by default). This plane can be modified by using Layers > Symmetry > Set Plane.

Moving the bottom CV automatically moves its symmetric twin (blue circle) in the opposite direction to maintain the symmetry.

After the curve or surface has been made symmetric, any transformation tool can be applied to the controls.
