I have objects on some layers in model space that don't show up in paper space. All the layers are on, thawed in current and all viewports, unlocked. The layers are visible in the layer box. There are objects from a consultant and also layers from an xref.
I'm using Autocad 2002.
I can get around this by creating a new layer and moving the objects to it. The layer and the objects show up in paper space. But I would like to prevent this from happening in the first place. Any Ideas how this happens?
