For a very long time now it's been possible to set any Layer to not Plot - make one like that for Viewports, and put them on it. But it's called what it is for a reason, and a Viewport is not a DEFinition POINT. That practice comes from the days when DEFPOINTS was the only Layer that would not Plot.
If that's the solution for you, it's almost certainly because when Layer 0 is either off or frozen, things on the DEFPOINTS Layer are visible, but cannot be selected, nor Osnapped to.Īllow me to make a suggestion: Don't put Viewports on the DEFPOINTS Layer.
