IMcGraphObjPolyNotifyCreationComplete Method

Sub NotifyCreationComplete

You must call the NotifyCreationComplete method before any object created, property change or coordinate move notifications will be sent to notify clients of the Overlay property (see McGraphOverlay.Add for an example). This serves two purposes: it avoids sending a bunch of expensive notifications during the process of object creation. It also allows an "abort" to be performed (as when the object is being created via user interaction) at any time until the NotifyCreationComplete method call is made, without notify clients having to "undo" their object tracking.
