I'm trying to model a 2 blade prop and could use some tips. I've tried using Helix with a 3/4 turn and a Sweep with a clam shell polyline (ie; () ) and it is close, but not quite. This is just for looks in a 3D model, not for manufacture.
This may not work better than Sweep, but you may want to try the Loft command instead. You could place a series of polyline shapes in sequence and use the guidelines to refine the appearance of your model.
Thanks for the reply. I ended up using a thin oblong spline and then Sweep with a 80 degree twist. I then used the original oblong spline, scaled it down a bit and then used Loft to make the blade end. I mirrored the blade and placed it on a 3D cylinder. Came out pretty good, at least for what I needed anyway.
