New Features in BladeGen 11.0:
Improved over/under-filed blades Supports longer filing lengths
Removed extrapolation of meanline to prevent pressure/suction curves from crossing; the result is that an over-filed, cut-off blade may be shorter than the original
Cut-off blades imported by BladeEditor should be unaffected by the extrapolation change
Improved TurboGrid export Additional information about the blade (surface lofting)
sent to TG through the .inf file
Proper .curve point markers for cut-off and square edged blades
