The transform from the coordinate space of the box to the model coordinate space.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.1090.0)

Syntax

C#
`public Transform Transform { get; set; }`

Visual Basic
`Public Property Transform As Transform Get Set`

Visual C++
`public: property Transform^ Transform { Transform^ get (); void set (Transform^ value); }`

Remarks

The transform must always be right-handed and orthonormal.

Examples

Copy C#

private void RotateBoundingBox(View3D view3d)
{
    if (!view3d.IsSectionBoxActive)
    {
        TaskDialog.Show("Revit","The section box for View3D isn't active.");
        return;
    }
    BoundingBoxXYZ box = view3d.GetSectionBox();

    // Create a rotation transform to apply to the section box 
    XYZ origin = new XYZ(0, 0, 0);
    XYZ axis = new XYZ(0, 0, 1);

    // Rotate 30 degrees
    Transform rotate = Transform.CreateRotationAtPoint(axis, Math.PI/6.0, origin);

    // Transform the View3D's section box with the rotation transform
    box.Transform = box.Transform.Multiply(rotate);

    // Set the section box back to the view (requires an open transaction)
    view3d.SetSectionBox(box);
}

Copy VB.NET

Private Sub RotateBoundingBox(view3d As View3D)
    If Not view3d.IsSectionBoxActive Then
        TaskDialog.Show("Revit", "The section box for View3D isn't active.")
        Return
    End If
    Dim box As BoundingBoxXYZ = view3d.GetSectionBox()

    ' Create a rotation transform to apply to the section box 
    Dim origin As New XYZ(0, 0, 0)
    Dim axis As New XYZ(0, 0, 1)

    ' Rotate 30 degrees
    Dim rotate As Transform = Transform.CreateRotationAtPoint(axis, Math.PI / 6.0, origin)

    ' Transform the View3D's section box with the rotation transform
    box.Transform = box.Transform.Multiply(rotate)

    ' Set the section box back to the view (requires an open transaction)
    view3d.SetSectionBox(box)
End Sub
