This should unlock all of the properties so that they can be modified. To change the settings try one of the following steps: Remove (unassign) the view template from the view. This is due to a view template being used for that view that is controlling the scale. So let's start by talking about the Ribbon a little bit. When trying to change the scale of a view or other settings like detail level, the settings are inaccessible - grayed out. Now as you can see the interface changes when you do that, and across the top of the screen is where we find the Quick Access Toolbar at the very top, and then beneath that, the Ribbon, which is organized into tabs, starting with Architecture on the left and ending with Modify on the right. Q: Can I join a Revit teamwork project with ARCHICAD as a read only client, using the RFA & RVT Geometry Exchange. So I'm just gonna click the Architectural Template link here and just create an empty architectural file. So in order to talk about these two interface elements we really need to have a file open in the background. Now the Quick Access Toolbar is displaying currently, but most of the tools are greyed out and the Ribbon is also mostly unavailable.
