I am trying to do roof flatten in my design, I did it but after flatten it looks that shape is not proper with fits to the circular wall, can anyone look at it and suggest any better idea to get the roof done with proper flatten patten. I try to create offset surface of the roof and then try to flatten that surface with surface flatten command but my surface flattens command gray out. it is not working in student version solidworks.
I appreciate if anyone has a different idea to create roof by splitting into 3 parts instead of 2parts.
I attached .rar file of my part please look at it.
