Cross-section of fuselages segments with guide curves not interpolated correctly.

[LucasKugler]

I have noticed that, when generating fuselages with guide curves, certain sections show a strange behaviour: instead of keeping a somewhat circular or ovoid shape like the sections that are being interpolated, the cross-section becomes almost diamond shaped, i.e. the faces between the guide curves get flattened.

This happens only when there is a large difference in size between the sections, and gets stronger when the size difference increases. In turn, large size differences are not a problem if there is no guide curve.

It would be nice if this could be fixed, as the models look much cleaner with the guide curves, and it avoids to clutter the cpacs file with dozens of sections. But right now the surfaces don't look right.
