The feature index of the first feature added; this index will be the same as the McFeatures.Count property before the new feature(s) were appended. The feature indices of any prexisting features will not have changed.
AddedCount
A Long value.
The number of features appended. The new McFeatures.Count will equal the old value plus this value.
Remarks
This event is fired after the ChangeMade event for only those methods that explicitly append features while leaving the McFeatures.Identifier unchanged for prexisting features. Actions that add features as part of some other action or ones that potentially change the McFeatures.Identifier for prexisting features will fire the Restructured event rather than this one.
