GH_Document Methods

The GH_Document type exposes the following members.

Methods
  NameDescription
Public methodActiveObjects

Public methodAutoLayoutComponents
Perform automatic layout on this document.
Public methodAutoSave(GH_AutoSaveTrigger)
Creates a new autosave file on the disk. The previous autosave file (assuming it exists) will be temporarily renamed and eventually deleted entirely. Note: AutoSave is only possible on Documents that have TopLevel Rank and a valid FilePath.
