When I opened my drawing this morinng, many of the layers/ classes do not show up in "savied views" and viewports as they are supposed to. I can turn on all layers and classes and all the information is still there, but when I get to view or viewport they dissapear even though the individual settings for the saved views and viewports show that the layers/ classes should be on.
Any help would be greatly appreciated. I am hesistant to cut /paste evrything into new drawing b/c I think I lose alll my svaed views and sheet layers.
I am a new user who is switching from ACAD and having a very frustrating time
