When implemented and registered as a protocol extension to an Autodesk.AutoCAD.DatabaseServices.Entity-derived class, this protocol extension interface specifies the communication with the grip editing complex for information on what alternatives can be provided to stretching grip points. 

These alternatives are represented as an array of modes (of type Autodesk.AutoCAD.DatabaseServices.GripMode). 

The grip editing complex is responsible for querying all available modes, interacting with the user to set the current mode, or switching between modes, and either:

• proceeding with grip dragging (if the current mode's action type is ActionType.DragOn),
• calling moveGripPointsAt once (if the current mode's action type is ActionType.Immediate)
• executing a command (if the current mode's action type is ActionType.Command).

Public abstract Class MultiModesGripPE
Inherits RXObject

public abstract class MultiModesGripPE : RXObject;

When the user hovers over a warm grip, the AutoCAD grip complex queries the grip'ed object for this protocol extension and retrieves the available modes. The current mode can be set during the warm grip stage through a multi-mode UI or during hot grip editing through Ctrl-cycling or context menu selection. 

Clients that implement this protocol extension for a given object type (Autodesk.AutoCAD.DatabaseServices.Entity derived) should either own the object type to be able to directly make its MoveGripPointsAt mode-aware or overrule the object's runtime MoveGripPointsAt behavior through GripOverrule.
