Parameters

Parameter	Type	Description
document	Document	The document.
stairsOrRampId	ElementId	The stairs or ramp to which the new railing will host. The stairs or ramp should have no associated railings yet. If the stairs are a part of <a href="8b07cbff-013c-889f-8807-703e63a91923.htm">MultistoryStairs</a> element railings will be populated on all levels.
railingTypeId	ElementId	The railing type of the new railing to be created.
placePosition	RailingPlacementPosition	The placement position of the new railing.

Return Value

Type	Description
ICollection	The new railing instances successfully created on the stairs.

Exceptions

Exception	Condition
ArgumentException	The stairsOrRampId is not a stairs or ramp element. -or- The railingTypeId is not a railing type.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	A value passed for an enumeration argument is not a member of that enumeration
InvalidOperationException	The stairsOrRampId already has associated railings or is in editing mode so association of railings is not permitted.
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.
ModificationOutsideTransactionException	The document has no open transaction.
