Used ‘Circle’ and ‘Follow Me’ tool to make this dome. But the “pie” shape lines, as in the attached image, I don’t understand and wonder if I can make a dome without them.
Can anyone inform me about the why and wherefore of these lines?
I would guess either the curved face weren’t sitting exactly on the blue/green axis or the way it were cleaned up before Follow Me. The second to last curved face looks pretty good though.
EDIT: One thing to note is that the endpoints of your circle seem to be off axis. Drawing them on the red/green axis makes getting the face for Follow Me aligned correctly to the circular path easier. That could have caused a problem, effectively skewing the face on the path.
Do you intend to have a hollow inside or do you want it to be a solid?
As I’m on my phone and can’t test this, I’m going to guess that it is being caused by your circle being off axis. This would make the profile not perpendicular to the start and end of the path, so you would get those extra faces.
When you draw your circles always pull them out along one of the axes.
Edit: tig posted as I typed, not very quick with my thumbs.
