The HatchPatternTable type exposes the following members.
Number of patterns in the table.
In Rhino for Windows 6.6, this member is inherited from CommonComponentTableTCount.
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.
Document that owns this table.
In Rhino for Windows 6.6, this member is inherited from RhinoDocCommonTableTDocument.
Conceptually, the hatch pattern table is an array of hatch patterns. The operator can be used to get individual hatch patterns. A hatch pattern is either active or deleted and this state is reported by HatchPattern.IsDeleted.
