normals flipping and UV export

[rranon]

Hello,

  I am currently trying Keyshot (last version, mac os X) and I have two issues to solve before I buy:
1 - is it possible to flip inverted normals? I have models imported from NX / step, and I need to flip normals on some faces
2 - is it possible to export to OBJ with the UV coordinates that I have set in Keyshot?

So far, I have not been able to do either of these...
Thanks for any help!
