Create Method (Document, IList(CurveLoop), ElementId)

Creates a new SiteSubRegion element with assigned TopographySurface to be hosted and adds it to the document.

Namespace: Autodesk.Revit.DB.Architecture
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)
Since: 2014

Syntax

C# 
public static SiteSubRegion Create(
	Document document,
	IList<CurveLoop> curveLoops,
	ElementId hostTopoSurfaceId
)
Visual Basic 
Public Shared Function Create ( _
	document As Document, _
	curveLoops As IList(Of CurveLoop), _
	hostTopoSurfaceId As ElementId _
) As SiteSubRegion
Visual C++ 
public:
static SiteSubRegion^ Create(
	Document^ document, 
	IList<CurveLoop^>^ curveLoops, 
	ElementId^ hostTopoSurfaceId
)

Parameters

document
Type: Autodesk.Revit.DB Document
The document to be modified.
curveLoops
Type: System.Collections.Generic IList CurveLoop
The boundary of the subregion.
hostTopoSurfaceId
Type: Autodesk.Revit.DB ElementId
The element id of a TopographySurface assigned to be a host of new created SiteSubRegion.

Return Value

The new SubRegion surface.

Remarks

This will create a new TopographySurface element which represents a subregion with a host TopographySurface assigned. If you need access to this Element you can obtain it from the TopographySurface property. See TopographySurface for details.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions 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. -or- The ElementId hostTopoSurfaceId does not represent a TopographySurface.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was null
Autodesk.Revit.Exceptions InvalidOperationException Failed to create the Sketch for the boundary of the current Subregion. -or- Cannot associate the new subregion with the assigned host because there is no geometric overlap, or they have mismatched design options. -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.
Autodesk.Revit.Exceptions 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.
Autodesk.Revit.Exceptions ModificationOutsideTransactionException The document has no open transaction.
