Creating 3D surface from u-v lines

I am trying to create a 3D surface from three lines - one border profile (green) and two intersecting  u,v lines (cyan and yellow) (see screenshot below). Does anyone have an idea how to achieve this? I have attached a dwg with the 3 lines.

Maybe like so?  attached dwg

Another method would be to generate intermediate Ellipses, then loft all of those to a central point.

I like the "intermedia ellpises" method a lot because the end geometry is very clean and simple. Just one question, when you are finishing the loft command, what option do you choose from the list below:

I used Cross Sections Only.  That happens to be the default, so a user can just hit 'Enter'.

Its interesting that when I execute the loft command I get a "Surface (Loft)" as and end result and in your example file the result was "Surface (Nurbs)". Did you do anything else with the surface after the loft command?

Leaving it as a "Loft" would allow for cross section modification at some later date, if the need should arise.  Converting to NURBS, especially if the surface is rebuilt to a lower Control Point density, reduces the data footprint to the file.

 

Doing one or the other sort of depends on what the eventual plan is for the geometry.
