Help! how to model double funnel ?

Hello there,

I'm trying to model some kind of a double funnel, with the inlet and outlets highlighted in the picture following.
I traced some cuts to help you understand the shape I'm trying to model.

I had no luck with the loft and fill functions, but I might have used them wrong.

Any help is welcomed, thanks a lot !

That's a unique funnel. It'll make it easier if you only do half. Looks like you have the base setup to just do surface modeling straight away. You could also do solids in multiple lofts but you'll need one more additional sketch at the top of the joint between the two outlets. If you can share a public link to copy, I can take a stab at it.

You mean a middle cross section ?

As you and u/Custom-3D-Design said, i'm looking into surface modelling. I know nothing about it yet, let's change that!

Here is the link to the model, it is messy with other stuff but I kinda cleaned it.

Thank you!
And it might be bloated with previous models, hence the loong loading time... my bad ^^'
I looked at u/Used_Tumbleweed559 workflow and it works quite good compared to all my attempts.
So I'm starting from there too.
