The Surface type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | CreateSnapshot |
Creates a snapshot that contains the current state of points and triangles resulting from previous Surface operations.
A snapshot can improve the performance of Surface builds from subsequent operations.
|
| ExportToDEM(String, String, Double, ExportDetermineElevationType) |
Exports the Surface to a DEM file.
|
| ExportToDEM(String, String, Double, ExportDetermineElevationType, Boolean, Single) |
Exports the surface to a DEM file, with an optional custom value for null elevation.
|
| FindDirectionAtXY |
Gets the direction of the Surface at the specified location (x, y).
|
| FindElevationAtXY |
Gets the elevation of the Surface at the specified location (x, y).
|
| FindSlopeAtXY |
Gets the slope of the Surface at the specified location (x, y).
|
| GetBoundedVolumes(Point3dCollection) |
Calculates the volume of an area defined by several points.
|
| GetBoundedVolumes(Point3dCollection, Double) |
Calculate the volume of an area defined by several points.
|
| GetGeneralProperties |
Gets the general properties of the surface.
|
| GetIntersectionPoint |
Gets the intersection point with surface by the specified point and vector.
|
 | GetProperty<Autodesk::Civil::DatabaseServices::GeneralSurfaceProperties> | |
| GetProperty<Autodesk::Civil::DatabaseServices::GridSurfaceProperties> | |
| GetProperty<Autodesk::Civil::DatabaseServices::TerrainSurfaceProperties> | |
| GetProperty<Autodesk::Civil::DatabaseServices::TinSurfaceProperties> | |
| GetProperty<Autodesk::Civil::DatabaseServices::VolumeSurfaceProperties> | |
| Rebuild |
Rebuilds the surface by processing all the operations one by one in the list.
|
| RebuildSnapshot |
Rebuilds the snapshot for the surface.
|
| RemoveSnapshot |
Removes the existing snapshot for the surface.
|
Properties
| Name | Description | |
|---|---|---|
 | Analysis |
Gets a SurfaceAnalysis object that exposes the surface analysis properties for the Surface.
|
| Application |
Gets the Application. Not currently implemented.
(Inherited from Entity.) |
| BoundariesDefinition |
Gets the collection of boundaries associated with the Surface.
|
| BuildOptions |
Gets an object that encapsulates options applied to building or re-building a Surface.
|
| 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.) |
| HasSnapshot |
Gets a boolean value that specifies whether the surface has a snapshot.
|
| IsOutOfDate |
Gets whether this surface is out-of-date.
|
| 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.
This indicates whether the referenced object can be found.
(Inherited from Entity.) |
| IsSnapshotOutOfDate |
Gets whether the snapshot in the surface is out-of-date.
|
| IsVolumeSurface |
Gets whether the surface is a volume surface.
|
| Lock |
Gets or sets whether the Civil 3D GUI shows this surface as locked.
|
| Masks |
Gets all the masks in the Surface.
|
| Name |
Gets or sets the Entity object's name.
(Inherited from Entity.) |
| Operations |
Gets the operation list for the Surface.
|
| ShowToolTip |
Gets or sets whether to show tooltips for the Entity.
(Inherited from Entity.) |
| StyleId |
Sets the Surface's style Id.
(Overrides Entity..::..StyleId.) |
| StyleName |
Gets or sets the Entity object's style name.
(Inherited from Entity.) |
