The Handle sub-object level in Editable Patch provides direct access to vertex handles, or vectors, without going through the Vertex sub-object level. Handles are still accessible at the Vertex sub-object level, but the Handle level provides enhanced features, as follows:
-
Select an editable patch >
Modify panel > Modifier stack display > 
Expand the Editable Patch entry. > Handle sub-object level
-
Select an editable patch > Modify panel > Selection rollout > (Handle)
- The ability to select multiple handles for transformation and application of operations such as Patch Smooth to them.
- Usage of the transform gizmo when manipulating handles.
- Elimination of the possibility of inadvertently transforming vertices.
- Support for named selection sets of handles.
- Copying and pasting handles.
- Use the Align tool for aligning handles.
