How would you model this propeller? It is a quite complex shape and I am stymied as to where to even start. Any and all ideas are welcomed.













Thanks for any help,
Nick

To get something with a twist in it like that you'll probably want to use Loft through some cross sections, you can rotate each cross section a little bit to make the twisting action.

For your particular case your one has a pretty broad flat area in it, so you might want to start out with a basic extrusion making a kind of totally flat block to start with and then model some twisted objects as cutting pieces and boolean difference them away from the block, leaving the original flat block area in the middle of the shape.

Two-profile, two-rail sweeps are wonderful tool for things like wings and props. I attached a quick model that can be the base for further work - it all depends on how faithful you want to be to the original item.
