Perfect - many many
thanks! 

It worked on the triangle mesh AND on the ruled surface. Both
STL files read into other apps just fine. The ruled surface output is
appreciably higher quality even than a very high poly count mesh. 

For
the record... 

// write out a STL file 
// run a triangle filter ruled
surface to create polys 
vtkSmartPointer<vtkTriangleFilter> 
tris =
vtkTriangleFilter::New();

tris->SetInputConnection(ruled->GetOutputPort());

vtkSmartPointer<vtkSTLWriter> 
stlWriter =
vtkSmartPointer<vtkSTLWriter>::New();

stlWriter->SetFileName("Ruled.stl");

stlWriter->SetInputConnection(tris->GetOutputPort());

stlWriter->Write(); 

And 

// write out a STL file
 // run a triangle
filter on the mesh to create polys
 vtkSmartPointer<vtkTriangleFilter>

tris = vtkTriangleFilter::New();

tris->SetInputConnection(ruled->GetOutputPort());


vtkSmartPointer<vtkSTLWriter> 

stlWriter =
vtkSmartPointer<vtkSTLWriter>::New();


stlWriter->SetFileName("Mesh.stl");

stlWriter->SetInputConnection(tris->GetOutputPort());

stlWriter->Write();
