Isolate Selection legacy Mode for 2013
In previous versions of 3ds Max the Isolate Selection was implemented using MAXScript.
In 3ds Max 2013, the functionality was reimplemented as an integral part of the User Interface.
Due to this update the Isolate mode is now a toggle. This changes the legacy ability to isolate selected objects that are already isolated like what was possible in 3ds Max 2012 and previous versions.
This script restores the legacy functionality when assigned to a keyboard shortcut and was created as a functional example of the code.
