At all times, there is a "current" hatch pattern. Unless otherwise specified, new objects are assigned to the current hatch pattern. The current hatch pattern is never locked, hidden, or deleted.

Namespace:  Rhino.DocObjects.Tables
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
public int CurrentHatchPatternIndex { get; set; }
