PS That works also for the Pure Nurbs object but top/bottom face are erased!



Tried with STL file
I must have missed something! :)
(not sure of what exactly must be selected...the vertical between polygons ? or only the polygons "curvated", both or something else... )
Circles are fine but the rest... are missing!
or it's to me to "and lets you alone to rebuild it". :)
