Public Shared Function Create ( _
	document As Document, _
	viewId As ElementId, _
	hostElementId As LinkElementId, _
	referenceOption As StairsNumberSystemReferenceOption, _
	placementLevelId As LinkElementId _
) As NumberSystem

public:
static NumberSystem^ Create(
	Document^ document, 
	ElementId^ viewId, 
	LinkElementId^ hostElementId, 
	StairsNumberSystemReferenceOption referenceOption, 
	LinkElementId^ placementLevelId
)

Parameters

document
Type: Autodesk.Revit.DB Document
The document.
viewId
Type: Autodesk.Revit.DB ElementId
The view in which the NumberSystem will be created.
hostElementId
Type: Autodesk.Revit.DB LinkElementId
The host id on which the NumberSystem will be created.
referenceOption
Type: Autodesk.Revit.DB.Architecture StairsNumberSystemReferenceOption
The reference option of the NumberSystem.
placementLevelId
Type: Autodesk.Revit.DB LinkElementId
The id of the level on which the NumberSystem will be placed. The placement level must be one of the base levels of a stairs group members. It is suggested to get the level from MultistoryStairs.GetStairsPlacementLevels().

Return Value

The created NumberSystem.

Remarks

In multistory stairs, a stairs element could be a stair group or individual stair. This method allows to add a NumberSystem for a run of an individual stairs or a stairs group member on the placementLevelId.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException viewId is not valid for placement of a NumberSystem (only floor plan views and elevation views are permitted). -or- hostElementId is not valid as a host for NumberSystem (only StairsRun elements are permitted in this release). -or- The reference option is not valid for a NumberSystem. -or- The placementLevelId is not one of the stairs base levels, or is higher than the elevation of viewId. -or- The hostElementId already has a number system.
