It seems imported STL files stay facetted. Is there a setting (degrees) for creating smoothed normals between adjacent polys? For some reason I thought I remember a setting-- perhaps it was a different version? or program :-[
I played with .STL files in KS a while back and found that if I processed the files through MeshLab, they then imported fine.

I've forgotten exactly what I did, but it was something along the lines of smoothing normals
