Yes.  Or even just wire frame countour lines on a 3d scene.

Ptplot does not support contour plots.  In principle it could be
extended, to support contour plots, but it would take quite a bit of
effort.

The Matlab demo in Ptolemy II 2.0.1 at
ptII/ptolemy/matlab/demo/MatlabExpression/MatlabExpression.xml the
Matlab surf() function to do a 3d plot.

So yes, using Matlab would be best way to proceed.

For what I'm looking for it is a bit of a sledge hammer to drive a nail, at least
at the > $1000 level for several people...

I wonder if some hack of creating a ptolemy.domains.gr.lib.PolyLine3D or taking
the PolyCylinder3D and adding a second polygon for the top edge of the cylinder
would permit something simplistic? Just a thought.

   Has anyone out there built a contour plotter?  Or do
   people depend on MatLab for this?
