Compute FingerPrint of the Entity.

Creates a new instance of a GridVolumeSurface object and adds it to the database where the base surface specified by baseSurfaceId is located.

Creates a new instance of a GridVolumeSurface object and adds it to the database where the base surface specified by baseSurfaceId is located.

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.

Exports the Surface to a DEM file.

Exports the surface to a DEM file, with an optional custom value for null elevation.

Gets the direction of the Surface at the specified location (x, y).

Gets the elevation of the Surface at the specified location (x, y).

Gets the points on the surface along the specified line segment.

Gets the slope of the Surface at the specified location (x, y).

Calculates the volume of an area defined by several points.

Calculate the volume of an area defined by several points.

Gets the general properties of the surface.

Gets the Grid properties of the surface.

Gets the intersection point with surface by the specified point and vector.

For Data Shortcut reference entity (IsReferenceObject == true), gets the entity's reference information.

Gets the Volume properties of the surface.

Rebuilds the surface by processing all the operations one by one in the list.

Rebuilds the snapshot for the surface.

Removes the existing snapshot for the surface.

Gets a SurfaceAnalysis object that exposes the surface analysis properties for the Surface.

Gets the Application. Not currently implemented.

Gets or sets whether to rebuild the surface when surface definition is changed.

Gets the collection of boundaries associated with the Surface.

Gets an object that encapsulates options applied to building or re-building a Surface.

Gets or sets the cut factor for the surface.

Gets or sets the Entity object's description.

Gets the Entity object's display name.

Gets the Document. Not currently implemented.

Gets or sets the fill factor for the surface.

Gets or sets FingerPrint of the Entity.

Gets the folder ObjectId of the Entity Returns ObjectId::Null if the Entity is located in root folder

Gets a boolean value that specifies whether the surface has a snapshot.

Gets whether this surface is out-of-date.

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.

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.

For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is stale.

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.

For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is valid.

Gets whether the snapshot in the surface is out-of-date.

Gets whether the style is used by other objects in the current drawing.

Gets whether the surface is a volume surface.

Gets or sets whether the Civil 3D GUI shows this surface as locked.

Gets all the masks in the Surface.

Gets or sets the Entity object's name.

Gets the operation list for the Surface.

Gets or sets whether to show tooltips for the Entity.

Sets the Surface's style Id.

Gets or sets the Entity object's style name.
