For "blobby" forms

- Extrude Base
- 2 curves projected
- Trim
- Scale Bottom piece trickily (aligned on the Bottom face)
- Naked
- Blend (you can regulate the Bulge - Maybe use the Planar section for the bottom vertical face)
(if you want make Fillets better to kill bottom vertical face and make it "Planar" )



Blend with planar section option


Blend elaborated so you can put heavy bulge! :)


Arc without headache! :)


The trick of the Scale




PS you can even go more speedy in drawing only one curve projected! ;) Result will be the same!
(if you want same form Top / Bottom)
So ultra speed! :)
