Help with making a dome type roof for realism build

Hello all, I’m currently working on a project and I’m at a standstill with a specific part…

I’m trying to replicate the dome roof seen in this reference picture

What I currently have built

I’m kind of stumped as to how I should make this, and I should mention that I don’t want to use blender.

If anyone has some tips or knows any plugins that can be useful please let me know

Thanks!

You could use blender for a mesh or unions with studio.
