Must say that I am absolutely delighted with my recent investment in MOI !!!

I have - however - run into a little trouble trying to model the engine cowl in the attached aircraft.

I can create a surface from the propeller spinner opening to the rear surface - but not from both the prop spinner opening plus the air intake opening.

The TK4 aircraft was designed in 1937 when all complex surfaces would have been created by hand, by pattern makers - and may not be mathematically accurate.

I know MOI is not really meant for "reverse engineering" - but any suggestions from experienced users would be greatly appreciated.
