// ShpLineD.h  -  Definition of the degenerated line shape in the XY plane.
// -------------------------------------------------------------------------
// Description:
//
// This shape definition is used in the axisymmetric shell elements.
// The main difference from the other shapes is that the geometry is
// not solely defined by the nodal coordinates, but also by the
// nodal vectors. See node class for definition of these vectors.
