Sub d in Rhino 6

Been experimenting with Rhino 6 WIP (Sub D)

Extruded a form from curve to experiment on
Went to SubDFromMesh

No bounding box comes up to manipulate the form from though

Can anyone give me a heads up what might be wrong ?

Thanks !

Hi Brett - you can turn on control points for the resulting object - F10/PointsOn command- is that what you mean?
