AreaReinforcement.Create(Document, Element, IList<Curve>, XYZ, ElementId, ElementId, ElementId) Method

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

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.4.0.0 (26.4.0.0)

Syntax

C#

public static AreaReinforcement Create(
	Document document,
	Element hostElement,
	IList<Curve> curveArray,
	XYZ majorDirection,
	ElementId areaReinforcementTypeId,
	ElementId rebarBarTypeId,
	ElementId rebarHookTypeId
)

Parameters

document Document: The document.
hostElement 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 IList<Curve>: An array of curves that will define the outline of the AreaReinforcement.
majorDirection XYZ: A vector to define the major direction of the AreaReinforcement.
areaReinforcementTypeId ElementId: The id of the AreaReinforcementType.
rebarBarTypeId ElementId: The id of the RebarBarType.
rebarHookTypeId ElementId: The id of the RebarHookType. If this parameter is InvalidElementId, it means to create a rebar with no hooks.

Return Value

AreaReinforcement
The newly created AreaReinforcement.

Exceptions

Exception	Condition
ArgumentException	The input curveArray is empty. -or- The input curveArray contains at least one helical curve and is not supported for this operation. -or- The element hostElement was not found in the given document. -or- the host Element is not a valid host for Area Reinforcement, Path Reinforcement, Fabric Area or Fabric Sheet. -or- Curves in curveArray are not closed and continuous. -or- areaReinforcementTypeId should refer to an AreaReinforcementType element. -or- rebarBarTypeId should refer to an RebarBarType element. -or- rebarHookTypeId should be invalid or refer to an RebarHookType element.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	majorDirection has zero length.
ForbiddenForDynamicUpdateException	This method may not be called during dynamic update.
