How to draw this tent roof

Hi !

I already draw other furniture and tents, but this one is causing me problem… Can anyone give me a tip or the step to do this? I’im using ‘‘follow me’’ tool to draw the others, but I can’t figure out the pattern of this one…

Thank you !

I’d draw the outline of it and use Curviloft from Fredo6 to create the surfaces.
