Import Frame Reference Sketch
Create Reference Planes
Make planes where the frame begins and ends
Make planes where the shell begins and ends
Make a plane at the bottom of the shell
Create side view sketch of the middle and bottom shell
Create a top view profile for the middle shell
Convert entities the middle shell profile into a new sketch
In a new sketch, Convert Entities the middle shell profile and then linear sketch pattern it downwards (2 inches), this creates the upper fillet reference
Add 2 points into the same sketch, where the upper fillet intersect with the bottom shell profile
Make a new sketch, and draw an airfoil between the 2 points from the step above.
