Trying to create a sweep that changes shape as it follows the path

andersanders Member Posts: 4
I am trying to model a wing but when i try to make the profile with a sweep it leaves flat spaces down the wing:

I want my curves end point to stretch to the middle line while still keeping the main curvature.

    Thank you very much it was what i wanted to do. I went ahead and tried your method for myself and it thaught me alot about onshape :)
    It is indeed an aircraft, i am trying to model a skeleton of a plane so that i can print the drawings and create a radiocontroller version of it. I haven't come that far yet though only have the one wing

    @andrew_troup guide curves can be used with the loft. I have been surprised by what can be achieved with this command. Checkout the body on this, a point to point loft with 1 elliptical profile and 2 guide curves.  

    edit* this different to the sweep as mentioned above, sweep does not have guide curves, loft however does have guide curves and may be used in some scenarios to achieve the desired result that sweep will not.d

    I should perhaps have been more clear in the latter stages of my post:
    I guess I thought it was self-evident that lofts (unlike sweeps) DO permit guide curves.

    Nice model, BTW!

    @andrew_troup I think I just confused loft and sweep. I will edit my post.

    Hi @anders,  I am happy that it is help of you.

    Speaking of 'Sweep', it is simple command and make a simple surface.
    In Part 'bolt M10' of 'bolt and nut M10'

      https://cad.onshape.com/documents/7d889a653d1c4b3883cb97e8/w/65003e9ea8434b75a7a36ecb

    I use 'Sweep1' using 'Sketch 5' and 'Helix 1' and get a spiral solid.
    The face outside of screw is merged with cylinder surface which has the same external diameter to be one face.
    When I do the same thing in SolidWorks, they remain different faces, not to be one face.
