Designing oil sump fins

[masterkorp.alfredo]

Hello,

Thanks for your suggestions!

I've made some progress today.


Now I want to make some fins on the inside like I did on the outside.

But I am not finding a way to get the constructions line of all of the inner shape. The objective is to make the inner fin a single piece that would surround all the pads.

Any suggestions ?

Something like this?
