Hello Ken,

I was asking the first question.  I implemented the vtk file format for an
unstructured grid using:
type 10 elements for 3D (tetrahedra)
type 5 elements for 2D (triangles)
type 3 elements for 1D (lines)

Each of these elements are defined in terms of points.

My data only exists on points (point data).

Is there any reason why I would want to put the lower dimensional elements
in my vtk file in addition to the highest dimensional elements?
