Envelope disappears when opening sketchup
I get this message when I open up Sketchup. My colored envelope boxes disappear after I click OK. When I recheck the layers I cant restore it. Help please!

icon in the OS toolbar and NOT using File>>Save/Save As in the SketchUp Application. Various toolbars for OS can be made visible using the View>>Toolbars option...
Saving the file in the SketchUp application does not save any of your Openstudio features, which I think could be one reason why your envelope is 'disappearing'.
