Hi. Try to cretaing the curve in a CAD software (Catia, ProE, Solidworks...). You have to import the points that define the curve, and create the curve.

Then export the curve to .IGS (.IGES). Then in blade gen, import the curve that define the airfoil.

BladeGen will always represent the leading and trailing edges as ellipses or cut-off. If you have a sharp leading or trailing edge, just specify the ellipse size to be very small, but not zero.

To import you profile points into BladeGen, have a look at the TurboGrid .curve format or the RTZT format. Both are documented in the on-line help.
