Hi all,

I don't really know hot to verbalize my needs and I don't really know how to search for that.

I want to build a special roof which consist of a half cylinder that is scaled down a bit (see attached picture). Scaling the object my subdivision cap (the inner edge) will be also squeezed. I need to have the same distance in the upper area as at the left or right area (a parallel edge??) in order to be able to build more or less the same roof as in picture two attached.
I have no clue how I could make it.... Need the help of your experience and professionalism

Could you tell me how you would build up that roof?
