I hope I can explain what I am asking…
Say I had a model like this:
And then turn on Hidden Geometry and delete a line, I get this:
How do I fix it, respecting the curved surface? I know I can draw a line:
But then when I turn off Hidden Geometry I now have a line:
I can hide it and it seems to work:
But when I look at hidden geometry the line is different:
Is there another way to handle this?
