Executing this form with the “loft” command would seem impossible, especially if you want to maintain tangency with the two respective surfaces.
(with the analogous tool of NX it is easily executable).
Why don’t I add a “Chain” option in the Loft command? Why hasn’t a major continuity option been added yet? (G2).
Furthermore, it is possible to set a tangency with the circular bottom surface, but with the upper polylobed one it is impossible.
Furthermore, after creating the shape, if I want to give a thickness, the problems begin: neither with srf offset nor with shell it is possible. Could you prove that you are better?

P.S. This form could be modeled with the “Blend srf” command, even if the result in the upper part is not the desired one (see at 6:26).
