I placed lines, curves, and angle lines on the same level at the same time,
but when I moved the plane, both lines and curves disappeared immediately.
Why didn’t the angle lines disappear?
I want the angle line to be shown only at the placement level, and how to make it disappear at other levels as well.
Thanks for reporting this. I can reproduce this too. It seems to be an issue with the projection visibility feature. Maybe @Sunderlandkyl could have a look?
