Properties

  NameDescription
Public propertyAnalysis
Gets a SurfaceAnalysis object that exposes the surface analysis properties for the Surface.
(Inherited from Surface.)
Public propertyApplication
Gets the Application. Not currently implemented.
(Inherited from Entity.)
Public propertyBoundariesDefinition
Gets the collection of boundaries associated with the Surface.
(Inherited from Surface.)
Public propertyBuildOptions
Gets an object that encapsulates options applied to building or re-building a Surface.
(Inherited from Surface.)
Public propertyCells
Gets all visible cells in the GridSurface.
Public propertyDEMFilesDefinition
Public propertyDescription
Gets or sets the Entity object's description.
(Inherited from Entity.)
Public propertyDisplayName
Gets the Entity object's display name.
(Inherited from Entity.)
Public propertyDocument
Gets the Document. Not currently implemented.
(Inherited from Entity.)
Public propertyHasSnapshot
Gets a boolean value that specifies whether the surface has a snapshot.
(Inherited from Surface.)
Public propertyIsOutOfDate
Gets whether this surface is out-of-date.
(Inherited from Surface.)
Public propertyIsReferenceObject
Gets whether the Entity is a reference object. A reference object is located in another drawing, and linked using a data shortcut or Vault. If the entity is native to the current drawing this property returns false; if it is being referenced via data shortcuts or AutoCAD Vault it returns true.
(Inherited from Entity.)
Public propertyIsReferenceStale
For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is stale.
(Inherited from Entity.)
Public propertyIsReferenceSubObject
For reference objects (IsReferenceObject == true), gets whether the Entity is a reference subobject. For example, when iterating through the structure of a pipe network referenced from another drawing, this property is true for each entity.
(Inherited from Entity.)
Public propertyIsReferenceValid
For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is valid. This indicates whether the referenced object can be found.
(Inherited from Entity.)
Public propertyIsSnapshotOutOfDate
Gets whether the snapshot in the surface is out-of-date.
(Inherited from Surface.)
Public propertyIsVolumeSurface
Gets whether the surface is a volume surface.
(Inherited from Surface.)
Public propertyLock
Gets or sets whether the Civil 3D GUI shows this surface as locked.
(Inherited from Surface.)
Public propertyMasks
Gets all the masks in the Surface.
(Inherited from Surface.)
Public propertyName
Gets or sets the Entity object's name.
(Inherited from Entity.)
Public propertyOperations

(Inherited from Entity.)
Public propertyStyleId
Sets the Surface's style Id.
(Inherited from Surface.)
Public propertyStyleName
Gets or sets the Entity object's style name.
(Inherited from Entity.)
Public propertyVertices
Gets all visible vertices in the GridSurface.
