  There is some crazy curvature at the top edge.

  Thank you - could you send a screenshot of the curve / surface analysis options you used please? I can't seem to replicate what you saw.

  Take a look at the sketch called Former D…
  

  

  Specifically the direction of the curve at the left (as seen above) end. It is going in the wrong direction…
  
  Next, the Skin turtle decks 2 (Loft feature) should be made tangent to the previous loft. Currently there is a non-zero dihedral angle.
  

  

  
  Do the same for the Skin turtle decks 3 feature (make the start profile condition tangent to the edge of previous Loft)
  
  Now it will thicken with 2.1 mm. Any thicker than this towards the inside direction will fail as the curvature is too tight. Onshape has great diagnostics for all of these above issues mentioned, including this last one

  Thank you.

  I understand the start profile tangency requirements but I'm not sure what you mean by former D curve is going in the wrong direction?

  Zoom right in on the end of the spline in that sketch
