Actually for some reason they do not work as guidelines. These are not guides I made myself.
They showed up when I made the arc.
If I delete them, the whole surface and structure is also deleted.
Even if I uncheck the hidden geometry, the lines still mess up the “Painting” of my roof tiles.
It makes them into these sections.
Is it supposed to do this?
Maybe I am doing something wrong. After all I am not that skilled in this program.
So it might be something I am missing.
