Creating a Bulb Shape

I am trying to create this shape:


From the plans I have this grid patten.

What would be the best way to create a surface from this?

just had a quick try with your file, it’s a strange shape for sure, I kind of got it to work using loft command for the main dome section, then ntwrksrf for the 2 end segments, it’s certainly not perfect, you may need to look at the composition of your curves, maybe use the curvature graph ? I’m sure there are more advanced people on here who will advise you better

Thanks. I have a number of shapes like this that I need to generate. I can define them with grids but they do not match rhino constructs well.
