HOW TO DESIGN PROPELLER IN SOLID EDGE
It's a long but rewarding process. If you have a propeller, you'd cut it with a bandsaw in 10mm increments, clean and scan the section...
Insert the scans in your sketch views, - draw the appropriate 3rd order curves to generate that section. Eventually you will loft all those sections to make a blade. Then you mirror that feature to make a complete propeller.
