Parameters
- spatialElement
- Type: Autodesk.Revit.DBSpatialElement
 Specifies the spatial element needs to be computed, should be Room or Space.
Return Value
Requested boundary face information.Exceptions
| Exception | Condition | 
|---|---|
| Autodesk.Revit.ExceptionsArgumentException | spatialElement is not a room or a space, and thus has no 3D geometry to calculate. -or- spatialElement is not enclosed in 2d or has no location, or the height is too small, and thus has no 3D geometry to calculate. | 
| Autodesk.Revit.ExceptionsArgumentNullException | A non-optional argument was null | 
| Autodesk.Revit.ExceptionsInvalidOperationException | Failed to compute the given spatial element's geometry. |
