Syntax
Copy
public static ObjectId Create(
	string surfaceName,
	ObjectId baseSurfaceId,
	ObjectId comparisonSurfaceId
)

Parameters

surfaceName  String
The name of the new TinVolumeSurface.
baseSurfaceId  ObjectId
The ObjectId of the base surface for the TinVolumeSurface.
comparisonSurfaceId  ObjectId
The ObjectId of the comparison (top) surface for the TinVolumeSurface.

Return Value

ObjectId
Exceptions
ExceptionCondition
ArgumentException Thrown when:
  1. The surfaceName is empty.
  2. The baseSurfaceId is invalid or its type is not Autodesk.AutoCAD.DatabaseServices.Surface.
  3. The comparisonSurfaceId is invalid or its type is not Autodesk.AutoCAD.DatabaseServices.Surface.
Remarks
This method uses the default style for the surface so you don't need to provide a style ObjectId.
