How to create curved ellipsoid

Hello there,

I may have a simple question, but I’m looking for the best way to create a 3d shape according to the curves in the picture and file. I can describe it best as a “curved ellipsoid”, if there is a way with Rhino 3D or in combination with Grasshopper (I’m also familiar with it). I would appreciate any suggestions.

thanks in advance!

Create a straight Multipipe and then use the _Flow command. Tweak the sections before or after.

Hi @robpetersnb ,

Another option, split your “boundary curves” at their intersection points, delete your interior curves and circles.

Choose all curves and run “Network Surface”
