I am trying to create a dome style ring with a flat, round top. It will have 2 ct stone set in the top and a halo of 1.5mm stones set around it.
My first thought was to create the dome with Sweep 2 and 4 profiles, then cut off the top. But that top shape always is oblong, never round. So I gave up and did a hail mary with networksrf, but no. This is a common problem. Normally I make the left and right sides one surface and then make two other sides, but I have to have a dome shape for this job.
Here are the curves, exactly where I need them (fillets are optional):
