Example

C#

private void CreateStairsPath(Document document, Stairs stairs)
{
    Transaction transNewPath = new Transaction(document, "New Stairs Path");
    transNewPath.Start();

    // Find StairsPathType
    FilteredElementCollector collector = new FilteredElementCollector(document);
    ICollection<ElementId> stairsPathIds = collector.OfClass(typeof(StairsPathType)).ToElementIds();

    // Find a FloorPlan
    ElementId planViewId = ElementId.InvalidElementId;
    FilteredElementCollector viewCollector = new FilteredElementCollector(document);
    ICollection<ElementId> viewIds = viewCollector.OfClass(typeof(View)).ToElementIds();
    foreach (ElementId viewId in viewIds)
    {
        View view = document.GetElement(viewId) as View;
        if (view.ViewType == ViewType.FloorPlan)
        {
            planViewId = view.Id;
            break;
        }
    }

    LinkElementId stairsLinkId = new LinkElementId(stairs.Id);
    StairsPath.Create(stairs.Document, stairsLinkId, stairsPathIds.First(), planViewId);
    transNewPath.Commit();
}
