[Beginner] How to Sweep in 3 dimensions ?

Hello, 

Just starting on Onshape and I'm having quite a lot of fun with this app. I'm trying to make a wind turbine blade (well a bail as it's a vertical wind turbine using darrieus and savonius ideas). 

You can see it here : https://cad.onshape.com/documents/1c8d1ba8f1872615985dd48a/w/6685c8eb5573101f4cc4f05b/e/e1872d9dcad7fff568bb0cac

My problem is about how can I sweep the path in 3 dimensions (x, y and z axes). Well for now I can sweep following a line with a rotation so I have 2 dimensions x and y. 

But I need it on z as well (aerodynamic purpose). Kind of rotation, like the Helix tool but it doesn't work here. I also tried the "Move Face" tool but it's not working. 

I hope that makes sense, I have no idea about how I can do it. But I'm trying to reproduce an other part (designed on another software) so I know it's possible.

Please let me know if you need any other detail. 

Thank you :)

    Hi, 

    Based on my understanding of your questions I did the following.

    The shown steps are:

    1. Profile on Right plane
    2. Diagonal Line on the top plane in order to create a "point normal" plane for the second sketch
    3. Second sketch added and moved a bit higher than the first one
    4. Loft applied between the two sketches.

    I hope this is helpful to you.

    Hello, 

    Thank you again Tarek for the tricks here ! I'm almost finished. I'm just stuck on a last point... As you can see here : 

    I have 2 paths and a loft to fill it up. However, I need my Path2 to be rotated with my Path1. And I already tested to add a contraint, rotate the new plan and several other things but no result so far :/ 

    Like this : 


    I've looked on several other forum threads and it seems Onshape doesn't have any rotation tool right ? 

    Thank you very much for the help ! :)
