	Document document,
	CurveLoop curveLoop,
	ElementId railingTypeId,
	ElementId baseLevelId
)
Visual Basic 
Public Shared Function Create ( _

public:
static Railing^ Create(
	Document^ document, 
	CurveLoop^ curveLoop, 
	ElementId^ railingTypeId, 
	ElementId^ baseLevelId
)

Parameters

document
Type: Autodesk.Revit.DB Document
The document.
curveLoop
Type: Autodesk.Revit.DB CurveLoop
The railing path which the new railing will be created along with. The curveLoop should be continuous with curves which are only bounded lines and arcs on the same horizontal plane.
railingTypeId
Type: Autodesk.Revit.DB ElementId
The railing type of the new railing is to be created.
baseLevelId
Type: Autodesk.Revit.DB ElementId
The base level on which the new railing will be created.

Return Value

The new railing instance if creation was successful, otherwise a null reference ( Nothing in Visual Basic) .

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException curveLoop is empty. -or- curveLoop should only contain lines or arcs. -or- curveLoop is not continuous. -or- Not all curves in curveLoop are on the same horizontal plane. -or- The railingTypeId is not a railing type. -or- The baseLevelId is not a valid level id for a railing.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions ModificationForbiddenException The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
