6. Define element types.

Define two element types:  a 2-D element and a 3-D element.  Mesh the wing cross-sectional area with 2-D elements, and then extrude the area to create a 3-D volume.   The mesh will be "extruded" along with the geometry so 3-D elements will automatically be created in the volume.
