a Plane in OCAF

Forums: 

I made a plane by TDataStd_Plane class.
But I cannot modify the attributes of the plane. For example, the size of the plane.

TPrsStd_AISPresentation::GetAIS() was useless. The object obtained by GetAIS() is AIS_InteractiveObject object. But I cannot downcast it to AIS_Plane object.

Please, tell me the way about the attribute of the plane made by TDataStd_Plane.
