SyntaxThe GridSurface type exposes the following members.
Properties| Name | Description | |

Gets a SurfaceAnalysis object that exposes the surface analysis properties for the Surface.
(Inherited from Surface) |
| Application |
Gets the Application. Not currently implemented.
(Inherited from Entity) |

Gets or sets whether to rebuild the surface when surface definition is changed.
(Inherited from Surface) |
| BoundariesDefinition |
Gets the collection of boundaries associated with the Surface.
(Inherited from Surface) |
| BuildOptions |
Gets an object that encapsulates options applied to building or re-building a Surface.
(Inherited from Surface) |
| Cells | Gets all visible cells in the GridSurface. |
| DEMFilesDefinition | |
| Description |
Gets or sets the Entity object's description.
(Inherited from Entity) |
| DisplayName |
Gets the Entity object's display name.
(Inherited from Entity) |
| Document |
Gets the Document. Not currently implemented.
(Inherited from Entity) |
| FingerPrint |
Gets or sets FingerPrint of the Entity.
(Inherited from Entity) |
| FolderId |
Gets the folder ObjectId of the Entity
Returns ObjectId::Null if the Entity is located in root folder
(Inherited from Entity) |
 | HasSnapshot |
Gets a boolean value that specifies whether the surface has a snapshot.
(Inherited from Surface) |
| IsCWSReferenceObject |
Gets whether the Entity is a Civil Worksharing reference object. A Civil Worksharing reference object is
a Civil object shared to Shared Space. It is not editable. But it can be updated to the new version in the Shared Space.
(Inherited from Entity) |
| IsCWSSourceObject |
Gets whether the Entity is a Civil Worksharing source object. A Civil Worksharing source object is
a Civil object shared to Shared Space. It is editable and can be updated to Shared Space.
(Inherited from Entity) |
| IsLevelOfDetailEnabled |
Gets or sets whether to reduced level of Detail.
(Inherited from Surface) |
| IsOutOfDate |
Gets whether this surface is out-of-date.
(Inherited from Surface) |
| IsPartialReferenceObject |
Gets whether the surface is partial reference surface.
(Inherited from Entity) |
| IsReadOnlyReferenceObject |
Gets whether the Entity is a readonly reference object. A readonly reference object is
either a data shortcut referece object or a Civil Worksharing reference object.
(Inherited from Entity) |
| IsReferencedSourceExisting |
For reference object (IsReferenceObject == true), it will try to get its source entity while opening a drawing.
This indicates whether the reference object has source entity.
(Inherited from Entity) |
| IsReferenceObject |
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) |
| IsReferenceStale |
For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is stale.
(Inherited from Entity) |
| IsReferenceSubObject |
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) |
| IsReferenceValid |
For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is valid.
(Inherited from Entity) |
| IsSnapshotOutOfDate |
Gets whether the snapshot in the surface is out-of-date.
(Inherited from Surface) |
| IsUsed |
Gets whether the style is used by other objects in the current drawing.
(Inherited from Entity) |
| IsVolumeSurface |
Gets whether the surface is a volume surface.
(Inherited from Surface) |
| Lock |
Gets or sets whether the Civil 3D GUI shows this surface as locked.
(Inherited from Surface) |
| Masks |
Gets all the masks in the Surface.
(Inherited from Surface) |
| Name |
Gets or sets the Entity object's name.
(Inherited from Entity) |
| Operations |
Gets the operation list for the Surface.
(Inherited from Surface) |
| OriginationType |
Gets origination type which indicates the surface is created from a Corridor or Grading.
(Inherited from Surface) |
| PartialReferenceBoundaryManager |
Provides access to the manager for partial reference boundaries.
(Inherited from Surface) |
| ShowToolTip |
Gets or sets whether to show tooltips for the Entity.
(Inherited from Entity) |
| StyleId |
Sets the Surface's style Id.
(Inherited from Surface) |
| StyleName |
Gets or sets the Entity object's style name.
(Inherited from Entity) |
| Vertices | Gets all visible vertices in the GridSurface. |
Methods| Name | Description | |
|---|---|---|
 | AddPoint | Adds a point to the GridSurface. |
| ComputeFingerPrint |
Compute FingerPrint of the Entity.
(Inherited from Entity) |
 | Create(Database, String, Double, Double, Double) | Creates a new instance of a GridSurface and adds it to the specified database. |
| Create(String, Double, Double, Double, ObjectId) | Creates a new instance of a GridSurface and adds it to the database that contains styleId. |
| CreateFromDEM(Database, String) | Creates a new instance of a GridSurface from a DEM file and adds it to the specified database. |
| CreateFromDEM(String, ObjectId) | Creates a new instance of a GridSurface from a DEM file and adds it to the database that contains styleId. |
