Exceptions

Exception	Condition
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- The hostElementId already has a number system.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	A value passed for an enumeration argument is not a member of that enumeration

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.
