Trouble with converting (machup5) mesh body to solid body

[m_alzurghni123]

I'm trying to convert a mesh body of an aircraft design, which is an STL file exported from machup5 a cloud service for the design and analysis of aircraft, and this is my attempt to import the file to fusion and convert it to a solid body 
the first step is to insert a new mesh

secondly, after inserting the mesh, it needs to be repaired using the repair tool specifically to (close holes)

then generate a face group after some editing to combine them like this:

after that, I converted the mesh using the operation parametric and Method prismatic which leads to a deformed body in this screenshot:

Forget meshes in airplane modeling.
If you don't know the exact profiles, create mesh section sketches and draw the profiles with splines.

Edit

It is NACA 2412
So you can import it with "Airfoil Dat to Spline"

And yes, scale to the right size.

You cannot simply "convert" a mesh with compound curvature into a solid or surface body.

I think those aren't the dimension the original model had:

And especially not the lift-generating horizontal stabilizer.
