If you have point data in ASCII format you might be able to get some useful geometry in KeyCreator using:

Create>Spline>NURBS from Data

I have used Rhino 3D to generate planar, lofted NURBS through point clouds, but it will not convert an STL file to a NURBS object.  The computations and sippositions to do that are huge.  I ahve heard that GeoMAgic is a good program for it, but $$$.  I have never used it.

The STL - DWG conversions I have seen out of programs like MeshLab are basically faceted shells.  Pretty useless geometry for the most part.
