If you include a SoShapeHints node with an SoIndexFaceSetKit and give
the hints ( ORDERED & SOLID & CONVEX ), does Inventor automatically

1) Assume that normals are PER_FACE  
2) Create the normals for each face?

It seems like it should.  I guess another way of stating my question is
in what situations does Inventor compute the normals, relieving the
programmer from having to do so?
