Well i had a look and said no problem, i saw a bunch of planes which i could draw, constrain to a centre line, and rotate to compensate for blade twist angles. I planed to loft the sketches into one another.
Well it was a cute plan, but like most cute things, essentially useless. The sketches I so cleverly thought to loft into one another were actually radial projections. The blade is 8 inches and is divided into 8 sections starting at R=2.4" to the tip R=8"
i want to create flat, loftable sections to create the solid model, but you can see the problem, the angle of twist(which is not constant with respect to the distance from center point) messes with the possibility of creating nice flat sections. I think my best bet is to create a wireframe 3d sketch of all of the radial sections then use the points along the known paths to extrapolate flat planes.
One more thing. is it possible to create a curved sketch plane with inventor? i have 5.3, 6 and im getting a seat of 7.
Thanks alot for the help
