Hello all,

I am attempting to make the shape of the cover of this grill cooker and I am not really sure which would be best (meaning quickest) to use: surface or solid modeling. The curved sides are what is confusing me and I'm not sure where to start, at least, effectively.

Edit (7:51PM):

I was able to get the shape using boundary cuts and project curves but I have an issue with shelling. It can't shell to a good thickness I want, like 1/8" and it couldn't even shell at 1/128". So is there a better way than what I did so I can actually shell?

EDIT - 1:32PM (4/30)

I've added the corrected version of the example document for future forum users who will like to use this file or have this question.
