not quite lofting or sweeping

[roambotics_scott]

I'd almost bet I'm missing something because this seems so obvious but I often find myself wanting to do something like taking two perpendicular cross-sections and building a smooth body.. but there doesn't seem to be an easy way to do that starting with something like this

About the best / simplest thing I can do is to split those two cross-sections then loft all around and make a closed body

but I have no control over the tangency so I end up with something like

 

which seems very unnatural.

Even if I don't play with the handles on a spline loop, I get something much more reasonable [cross sectional comparision]

Now I know that I can go through and make a bunch of cross-sections and do traditional lofting but that takes something that feels like it should be doable in 5 minutes and makes a big project of it and it litters the design with construction planes and sketches.

It'd be great just to be able to loft using one cross section along the long axis and then the two perpendicular cross sections as rails but when I try that it tells me that the body would intersect itself.
