Hello,

Yes, that is correct. It also seems to work well when I tried out some lifting body sort of profiles instead of just ellipses. The two rail sweep gave a nice result as long as I made sure there was a profile set close to the nose to guide it properly. I fiddled around with moving the amount and position of the profiles and it seemed that an even distribution of profiles making sure that there were some close to the ends of the fuselage worked well. It takes a bit of work to get the curvature correct, but I found that Blending, Joining and Refitting the curves works. It is very easy to do this in Rhino+VSR but it can be done in MoI with a little more effort.
