Design view Representation locked

[Anonymous]

I am pretty new to Inventor and have no idea how to fix this problem. I have tried searching here on the forum but most solutions are to complicated for me so I do not know how to fix it. I get this false code: "The current Design View Representation is locked. Changes against it will not be saved. If you want to keep those changes please create a new Design View Representation or unlcok the current one." Is there someone that can explain this simple to me? I am using Inventor 2018

You likely have the master view rep active and made changes (visibility or whatever) that are normally saved but the master is always locked..

You need to switch back to the "default" view rep or create a new one..

Master is an "everything on and always everything on and you can't change that ever..."
