Help! Help! How to CAD model the topskin separately

[Karthik1130]

Hello all,
I have modelled and built the bottom skin of the wing of my own design of Foamboard rc airplane as a chuck glider.
Now i am planning to build top skin separately and hinge it over the leading edge of bottomskin using tape and build an FT Style foldable wing.
But i dont know how to model the topskin considering there will be 45degree bevel cut at the leading edge of bottom and topskin.

Please help in how to sketch the top skin.
A diagram would be helpful!

What you did looks good to me. We are building planes form foamboard, no need to be super precise. Close is good enough.
