Hi MoI users! I discovered MoI a few weeks ago and promptly bought a copy. I've been taking a crash course in using it. I'm building a model of an airplane, one I hope to feed into a CNC router to make a plug mould.

I'd like to make the shape of the air intake you see in the photos:


The is a fairly extreme transition. I found that I could get some curves to feed into the Loose Loft command by:
1) Building the profile curves forward and aft of the intake
2) Move/Copy those curves forward/backward so I can construct a pair of lofts that span the transition area.
3) Intersect each loft with an angled cutting plane and produce a series of curves using the Insect tool
4) Delete the 2 lofts
5) Re-loft everything with the loose loft tool.

Then I can loft the resulting set of curves using the Loose Loft function to create the transition. I found that 2 tightly spaced profiles before and after the transition produce the best results:


Not bad but not quite right. You can see the upper surface has a nasty twist at the transition point. Here with the points turned on you can see why:


I have tried a LOT of other ideas: networks, made cross hatching out of blended lines, rail lofts... I'm out of good ideas. I'm happy to go back to the drawing board. How would you tackle this problem?
