HistorySettings
Provides static (Shared in Vb.Net) properties to modify Rhino History settings.
Properties
Displays a warning dialog when an action is taken that breaks the link between the output and input objects.
When history object locking is enabled, objects with history on them act as if they were locked and the only way to modify these objects is to edit their inputs.
When history recording is enabled, new objects keep a record of how they were constructed so that they can be updated if an input object changes.
Enable history recording until the end of the next command
