The first image (Quetzal.png) shows what POVRay renders using Constructive Solid
Geometry and the next image in my next post (Rheingold.png) shows the best that
Rheingold/3DWin5 converter can do with it and it leaves out a tremendous amount
of detail.  Whole objects are missing, pyramids, stairways, interior walls, etc.
 I want to be able to export my object, complete, to something like Blender,
etc. and Rheingold was given the best rating on the POVRay.org website for
conversion utilities.  I really don't want to completely reconstruct objects
from the ground up in another program when I already have what I need
constructed in POVRay. Any help would be greatly appreciated.

Here is what Rheingold did with my file usnig the 3DWin5 conversion utility.

Here is what Rheingold and 3Dwin5 could do with it.

Not much help but I think that the question should first be addressed to 
Thomas Baier, the author of Rheingold/3DWin, as he can best answer to 
what extent csg objects built in POV-Ray can be converted to other 
formats. Mesh/mesh2 files and (smooth) triangle files should not give 
problems but complex csg... I don't know.

CSG objects built with Moray can be converted to meshes easily but... 
you cannot convert csg from POV-Ray to Moray.

I was afraid that I might get that answer and that is quite disconcerting.  I
can't imagine that this problem hasn't been addressed with POVRay being such a
popular package, but if it hasn't then it hasn't and I am dreading having to
build these objects in some other modeller.

A more learned person than I am could explain why csg constructions are
difficult to convert. It has been explained here in the past iirc but I forgot.

Personally, I model most of my objects externally. The primary reason is that in
my POV-Ray scenes I prefer to work with meshes which are more parse and memory
friendly and render faster, especially in crowded scenes. While I love pure csg
building, it has moved to the background for me.
