SiteSubRegion.Create(Document, IList<CurveLoop>, ElementId)

Became obsolete in 2025: This method is deprecated in Revit 2024 with the introduction of the new Toposolid elements. It is recommended that Toposolid elements should be used in place of TopographySurface elements.

document	Document	The document to be modified.
curveLoops	IList<CurveLoop>	The boundary of the subregion.
hostTopoSurfaceId	ElementId	The element id of a TopographySurface assigned to be a host of new created SiteSubRegion.
→ returns	SiteSubRegion	The new SubRegion surface.
