Blending two relative angled circular surfaces to have straight sections

Hi there,

I am trying to blend two angled surfaces and define four straight sections in order to have a continuous slope let’s say.

My grasshopper knowledge of organic/subd surfaces has always been rather limited so I have no clue where to start. I thought to divide it into the 8 sections and choose the four to be straight but did not get any further than that. I guess there has to be some blending done so the surface morphs together in some way.

The screenshot attached is the idea.

Hope you can help me.

file?

Something like that?
