Fusion 360 - Help with surface sweep of sketch along two paths

[jonniepickering]

Hi, I have two edges either side of a blade and I'd like to run a sweep of a sketch along between the two edges.

See image

Can anyone assist me with how to do this please?

I have highlight one edge, the other is the opposite side and you can see the sketch which is a simple arc that I would like to run the full length between the two paths.

Thanks

I might have misunderstood what I see in the scan. Is that the vehicle part (trunk lid) you are trying to attach your design to, or is that the design you are trying to duplicate ?

I would NOT build any geometry directly from mesh section sketches and most certainly not with a loft.

What you can see here is a scan of the actual tailgate of the car (3D scan).

I am creating a section sketch for two reasons.

The first is that I need to create a surface that I can use to split the body of my design in order that I can perfectly fit the design to the surface of the tailgate (3d scan).

The second reason is that I want to replicate (as closely as possible) the rear edge of the tailgate in my own design so that it looks like it's meant to be there. But I think what I'm hearing is that this is a mistake and that my design should be built 'from scratch'. If that's the case, how can I replicate the rear edge design?? I guess I could do it with some aproximity but then I will not be able to maintain the aerodynamic elements nor the aesthetics or the wing.

Does that make sense?

What direction would you recommend going in?

Use the scan ONLY as visual reference in creating your mating part. 
You can model the geometry well within any possible manufacturing tolerance.

OK, making sense now...

In that case, now I need to figure out how to make this black wing..

OK, here we go again...new attempt...

I have now built the blade from sketches, not using cross sections.

I had to turn the timeline off temporarily so I could delete some unwanted surfaces.

Attached is the model (well one side...)

I'd now like to chamfer the edges and also create a slight curve in the top surface but not sure how to do this.

Any help would be apreciated.
