CreateFromRebarShape Method

Creates a new shape driven Rebar, as an instance of a RebarShape. The instance will have the default shape parameters from the RebarShape, and its location is based on the bounding box of the shape in the shape definition. Hooks are removed from the shape before computing its bounding box. If appropriate hooks can be found in the document, they will be assigned arbitrarily.

static Rebar^ CreateFromRebarShape(
	Document^ doc,

)

Parameters

doc
Type: Autodesk.Revit.DB Document
A document.
rebarShape
Type: Autodesk.Revit.DB.Structure RebarShape
A RebarShape element that defines the shape of the rebar.
barType
Type: Autodesk.Revit.DB.Structure RebarBarType
A RebarBarType element that defines bar diameter, bend radius and material of the rebar.
host
Type: Autodesk.Revit.DB Element
The element to which the rebar belongs. The element must support rebar hosting; [!:Autodesk::Revit::DB::Structure::RebarHostData] .
origin
Type: Autodesk.Revit.DB XYZ
The lower-left corner of the shape's bounding box will be placed at this point in the project.
xVec
Type: Autodesk.Revit.DB XYZ
The x-axis in the shape definition will be mapped to this direction in the project.
yVec
Type: Autodesk.Revit.DB XYZ
The y-axis in the shape definition will be mapped to this direction in the project.

Return Value

The newly created Rebar instance, or a null reference ( Nothing in Visual Basic) if the operation fails.

Examples

Copy C# 
// Create 2 adjacent rebars with the given RebarShape and RebarBarType
private List<Rebar> CreateRebar(Document doc, Wall wall, RebarShape barShape, RebarBarType barType)
{
    List<Rebar> newRebars = new List<Rebar>();

    Rebar bar = Rebar.CreateFromRebarShape(doc, barShape, barType, wall, new XYZ(2, 0, 2), new XYZ(1, 0, 0), new XYZ(0, 0, 1));
    // call regenerate so that the TotalLength will be calculated before the transaction is committed
    doc.Regenerate();
    newRebars.Add(bar);

    // add a second bar adjacent to the first one
    double barLength = bar.TotalLength;
    bar = Rebar.CreateFromRebarShape(doc, barShape, barType, wall, new XYZ(2 + barLength, 0, 2), new XYZ(1, 0, 0), new XYZ(0, 0, 1));
    newRebars.Add(bar);

    return newRebars;
}
Copy VB.NET 
' Create 2 adjacent rebars with the given RebarShape and RebarBarType
Private Function CreateRebar(doc As Document, wall As Wall, barShape As RebarShape, barType As RebarBarType) As List(Of Rebar)
    Dim newRebars As New List(Of Rebar)()

    Dim bar As Rebar = Rebar.CreateFromRebarShape(doc, barShape, barType, wall, New XYZ(2, 0, 2), New XYZ(1, 0, 0), _
        New XYZ(0, 0, 1))
    ' call regenerate so that the TotalLength will be calculated before the transaction is committed
    doc.Regenerate()
    newRebars.Add(bar)

    ' add a second bar adjacent to the first one
    Dim barLength As Double = bar.TotalLength
    bar = Rebar.CreateFromRebarShape(doc, barShape, barType, wall, New XYZ(2 + barLength, 0, 2), New XYZ(1, 0, 0), _
        New XYZ(0, 0, 1))
    newRebars.Add(bar)

    Return newRebars
End Function
