SiteSubRegion.Create

Description:
Creates a new SiteSubRegion element and adds it to the document.

Remarks:
This will create a new TopographySurface element which represents a subregion. If you need access to this Element you can obtain it from TopographySurface.

Document

document

The document to be modified.
IList<CurveLoop>

curveLoops

The boundary of the subregion.

Return Value SiteSubRegion The new SubRegion surface.

ArgumentException

The input curve loops cannot compose a valid boundary, that means: no curve loop is contained in the given collection; these curve loops intersect with each other for some of them; or each curve loop is not closed individually; or each curve loop is not planar; or each curve loop is not in a plane parallel to the horizontal(XY) plane.
ArgumentNullException

A non-optional argument was null
InvalidOperationException

Failed to create the Sketch for the boundary of the current Subregion. -or- Cannot find an appropriate host TopographySurface for the Subregion. -or- The given curve loops intersect with curve loops of existing SiteSubRegions hosted on the same TopographySurface. -or- The boundary of SubRegion is entirely inside or overlaps at least one existing BuildingPad hosted on the same TopographySurface. This behavior is not allowed.
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.
