Parameters

style  RebarStyle

The usage of the bar, "standard" or "stirrup/tie".

barType  RebarBarType

A RebarBarType element that defines bar diameter, bend radius and material of the rebar.

startHook  RebarHookType

A RebarHookType element that defines the hook for the start of the bar. If this parameter is null, it means to create a rebar with no hook.

endHook  RebarHookType

A RebarHookType element that defines the hook for the end of the bar. If this parameter is null, it means to create a rebar with no hook.

normal  XYZ

The normal to the plane that the rebar curves lie on.

curves  IList<Curve>

An array of curves that define the shape of the rebar curves. They must belong to the plane defined by the normal and origin. Bends and hooks should not be included in the array of curves.

startHookOrient  RebarHookOrientation

Defines the orientation of the hook plane at the start of the rebar with respect to the orientation of the first curve and the plane normal. Only two values are permitted: Value = Right: The hook is on your right as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up." Value = Left: The hook is on your left as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up."

endHookOrient  RebarHookOrientation

Defines the orientation of the hook plane at the end of the rebar with respect to the orientation of the last curve and the plane normal. Only two values are permitted: Value = Right: The hook is on your right as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up." Value = Left: The hook is on your left as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up."

useExistingShapeIfPossible  Boolean

Attempts to assign a RebarShape from those existing in the document. If no shape matches, NewRebar returns or creates a new shape, according to the parameter createNewShape. When both parameters are "true", the behavior is the same as sketching rebar in the UI. At least one of these parameters must be "true". If the RebarShapeDefinesHooks flag in ReinforcementSettings has been set to false, and a RebarShape cannot be found with both matching curves and hooks, then this method will perform a second search, ignoring hook information.

createNewShape  Boolean

Creates a shape in the document to match the curves, hooks, and style specified, and assigns it to the new rebar instance. Shape creation will not succeed unless one or more other shapes already exist in the document, and these shapes have enough shape parameters to define a shape for these curves.

Return Value

RebarContainerItem
The Rebar Container Item.

Exceptions

Example

VB

Private Sub AddItemsToRebarContainer(container As RebarContainer, beam As FamilyInstance, barType As RebarBarType, hookType As RebarHookType)
    ' Define the rebar geometry information - Line rebar
    Dim location As LocationCurve = TryCast(beam.Location, LocationCurve)
    Dim origin As XYZ = location.Curve.GetEndPoint(0)
    ' create rebar along the length of the beam
    Dim rebarLineEnd As XYZ = location.Curve.GetEndPoint(1)
    Dim line__1 As Line = Line.CreateBound(origin, rebarLineEnd)
    Dim normal As New XYZ(1, 0, 0)
    Dim rebarLine As Curve = line__1.CreateOffset(0.5, normal)

    ' Create the line rebar
    Dim curves As IList(Of Curve) = New List(Of Curve)()
    curves.Add(rebarLine)

    Dim item As RebarContainerItem = container.AppendItemFromCurves(RebarStyle.Standard, barType, hookType, hookType, normal, curves, _
        RebarTerminationOrientation.Right, RebarTerminationOrientation.Left, True, True)

    If item IsNot Nothing Then
        ' set specific layout for new rebar as fixed number, with 10 bars, distribution path length of 1.5'
        ' with bars of the bar set on the same side of the rebar plane as indicated by normal
        ' and both first and last bar in the set are shown
        item.SetLayoutAsFixedNumber(10, 1.5, True, True, True)
    End If

    ' Hide the new item in the active view
    container.SetItemHiddenStatus(container.Document.ActiveView, item.ItemIndex, True)
End Sub
