void ArrayMesh::vertex_set_coordinates( VertexHandle vert,
                                          const Vector3D& coordinates,

  if (mDimension == 3) 
    coordinates.get_coordinates(coordArray+3*i);
  else if (mDimension == 2) {
    coordArray[2*i] = coordinates[0];
    coordArray[2*i+1] = coordinates[1];
  }
  else

                                         double length,
