Mathgroup,
I am wondering if anyone has done this. I have a colleague who would
like to modify a mathematica-generated surface in rhino (CAD software
which imports a large variety of 3d data files).
I've tried this:
(***start***)
ppts = Table[{Cos[t] Sin[p], Sin[t] Sin[p], Cos[p]}, {p, Pi/6, Pi,
Pi/12}, {t,
0, Pi, Pi/6}];
bspl = Graphics3D[{Green, BSplineSurface[ppts]}, Boxed -> False]
Export["test.wrl", b]
(**end**)
for 3ds, dxf, lwo, ply, pov, rib, and wrl. All of them appear to as
meshed surfaces and not nurbs. ply cannot be imported.
There is a 2008 mathgroup reference:

which claims to have done this for iges, , but the source is no longer
available as far as I can tell.
Thanks, Craig
