Axial fan blade

Hi folks,
did someone of you ever design an axial fan blade.
My problem is that i can only sweep alone a line, but
this does not help me in that special case.
The blade should get thinner towards the OD
and the stagger angle should get smaller.
I want to use an air foil profile from a data base in .iges
format.
Mit freundlichem Gruß / kind regards
