With quasi-streamline half-bodies and streamline half-bodies,the maximum area cross-section WOULD occur with the projected frontal area
With something like the Morelli shape,the maximum cross-section would NOT occur with the projected frontal area.
By establishing Cd based upon projected frontal area,we keep apples apples,and oranges oranges.
