Hello,

I am trying to model a propeller by boundary boss/base, so I have created several twisted and scaled airfoil sections and a couple of guide splines.

Detail of the tips:

When I select the guides in the first direction it seems to be all OK:

But when I select one of the guides in the second direction the model twist in one of the tips and I can't do anything to move the connectors. If I continue to add the second guide in the second direction the model don't even show up.

Thank you
