Create Method (Document, Element, IList(Curve), XYZ, ElementId, ElementId, ElementId)

Creates a new AreaReinforcement object from an array of curves. This method replaces the NewAreaReinforcement method, which has been deprecated.

static AreaReinforcement^ Create(
	Document^ document, 
	Element^ hostElement,

	XYZ^ majorDirection, 
	ElementId^ areaReinforcementTypeId,

Parameters

document
Type: Autodesk.Revit.DB Document
The document.
hostElement
Type: Autodesk.Revit.DB Element
The element that will host the AreaReinforcement. The host can be a Structural Floor, Structural Wall, Structural Slab, or a Part created from a structural layer belonging to one of those element types.
curveArray
Type: System.Collections.Generic IList Curve
An array of curves that will define the outline of the AreaReinforcement.
majorDirection
Type: Autodesk.Revit.DB XYZ
A vector to define the major direction of the AreaReinforcement.
areaReinforcementTypeId
Type: Autodesk.Revit.DB ElementId
The id of the AreaReinforcementType.
rebarBarTypeId
Type: Autodesk.Revit.DB ElementId
The id of the RebarBarType.
rebarHookTypeId
Type: Autodesk.Revit.DB ElementId
The id of the RebarHookType. If this parameter is InvalidElementId, it means to create a rebar with no hooks.

Return Value

The newly created AreaReinforcement.
