Return Value
Transformation matrix. Returns a null reference ( Nothing in Visual Basic) for analytical model elements that do not have local coordinate system. Origin returned by transform is point for which local coordinate system was calculated.Remarks
 For obtaining LCS at specified point on analytical model element use  [!:Autodesk::Revit::DB::Structure::AnalyticalModelStick::GetLocalCoordinateSystem()]  or  [!:Autodesk::Revit::DB::Structure::AnalyticalModelSurface.GetLocalCoordinateSystem()]  methods. 
 Exceptions
| Exception | Condition | 
|---|---|
| Autodesk.Revit.Exceptions InvalidOperationException | Thrown when called on Isolated Foundation, Wall Foundation or in-place analytical model element. Those elements do not support local coordinate system. |
