Dome using sweep help

I am struggling with the sweep command. I used sweep 1 to create all the other layers; however when I use sweep 1 for the top layer is creates this jut/ not smooth seamless point. I will have to export to AutoCAD so i was trying to keep them Poly surfaces. I am working RHINO 8

What’s your rail in use for the sweep? Also, could a partial revolve (or a full one followed by a trim of your objects) offer the same or equally-acceptable results?

Hello- please post a file with the input curves.

-Pascal

it looks like it is more a geometric problem.
the radius (pink) is smaller then the distance (cyan)

if you need more feedback post a file as @pascal wrote.
and you have to hurry, if you want him to answer before he gets retired.

Thank you, that helps. I think I have to change the rail to not create the curved distance problem
