Jon,
I went this route some months ago. {Connect} is not really meant for 3D,
although it will cope with a bit of surface topography. It won't work for a
closed surface like a sphere. Either you must somehow open-up and
flatten-out the surface, form the connections, and untransform the geometry
back to the original surface, or you must explicitly define the connections
in a DX native file.
I spent weeks on a program to do this (create triangular connections and
write to a DX file) for a specific problem. You can have the (VB) code if
you want to try to modify it yourself. Or, you might have some joy with
Eclectic.
DX really needs a module that can connect 3D closed surfaces and volumes
(in fact, it really isn't very friendly to scattered data). My web searches
only turned up references to proprietary or academic algorithms, so this
isn't a trivial problem.
