Syntax
public bool CheckGroundPlane( ElementId groundPlaneId )
Public Function CheckGroundPlane ( groundPlaneId As ElementId ) As Boolean
public: bool CheckGroundPlane( ElementId^ groundPlaneId )
member CheckGroundPlane : groundPlaneId : ElementId -> bool
Parameters
- groundPlaneId ElementId
- The element id to be checked to confirm that it is suitable to be a ground plane (i.e., that it is a level) or that it is invalidElementId. Setting ground plane with invalidElementId will lead to the ground plane being "reset".
Return Value
BooleanTrue if the input element is a level or invalidElementId, false otherwise.
