Good morning sir,

the blade tip is in contact with the shroud, defined as a revolve surface. In fact, the shroud surface is generated using one of the two tip sides. The same for the hub surface. These two surfaces are used for draw a projected sketch on a specific plane, in which, also the inlet and outlet section are drawn, for define correctly the FlowPath BladeEditor  feature.

So, what is your suggestion? Increasing the Hub/Shroud tolerance will not affect the blade shape like the blade height?  

This last question is related to the graphic result of hub/shroud tolerance: when it is increased the green lines (that represent hub and tip profiles) move toward the midspan profile. Can this movement affect, in example, the blade height?

Thank you
