I am unable to get revolve helix to work in DSM 6, while it works without any problems in DSM 5. While the revolve operation initially starts to extrude and revolve the surface around the designated axis, it stops after a single revolution and throws an error message, 'Failed to revolve as set of surfaces'. Since the very same operation works as expected in DSM 5, I am assuming that this is a bug. I am using V6.0.
Thanks
