StairsRunJustification justification
)
Parameters
- document Document
- The document.
- stairsId ElementId
- The stairs that the new stairs run will belong to.
- locationPath Line
- The line for location path of the new stairs run. The line has following restriction:
- The line should be bound line which is parallel to the XY plane.
- The Z coordinate of the line is the base elevation for the new run (in model coordinates). It must be greater than or equal to the stairs base elevation.
- The number of created risers will be calculated by rounding the length of the location path to a multiple of the tread depth.
- justification StairsRunJustification
- The location path justification of the new stairs run.
Return Value
StairsRunThe new stairs run.

Exception | Condition |
---|---|
ArgumentException | The stairsId is not a valid stairs element. -or- The input locationPath is not a bound line. -or- The input locationPath is not a valid location path line for straight run. -or- The locationPath is not valid line used as stairs path(probably it's too short). |
ArgumentNullException | A non-optional argument was null |
ArgumentOutOfRangeException | A value passed for an enumeration argument is not a member of that enumeration |
InvalidOperationException | The stairs element represented by stairsId is not in an active StairsEditScope. New components cannot be added to it. |
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. |
RegenerationFailedException | The locationPath doesn't satisfy restrictions to generate straight run. |

The new stairs run and the document will be regenerated. This should be run from within an open transaction.
