1. Project name. 2. Model picker. The number of opened models is displayed; clicking this button will open the list of all models in this project you have access to, with the option to load/unload any models in the current session. You can set **one** model as the **active** model, meaning that new geometry will be added in this model. You can also temporarily lock any model for the current session, to prevent accidental modifications. This lock is personal to you and does not affect other project members' access rights to these models. Next to the model picker, optionally the mode of your current session will be displayed. This can be either: 1. **Read only:** you only have [viewing access](/documentation/qonic-dashboard/models/model-access-rights.md) to this model, or you have opened a [public sharing](/documentation/qonic-dashboard/models/public-sharing.md) key, or Qonic has automatically enabled read only mode to prevent a [memory crash](https://help.qonic.com/documentation/qonic-application/basics/pages/9k6ZT9KI2mgQ7El5jk3D#qonic-crashes-in-the-web-browser.-whats-going-on). 2. **Conflict solving:** you are in a dedicated conflict solving mode because your previous changes conflict with the latest public version. Solve all conflicts before continuing to edit the model. 3. **Version Compare:** you are currently comparing two versions of a single model. This is a read-only mode dedicated to displaying the differences between these two versions. To compare two versions of a model, go the the [model version history](/documentation/qonic-dashboard/models/model-version-management.md), select one model version, click the Compare button and then select another model version. 3. [Command center](/documentation/qonic-application/querying-and-reporting/command-center.md): use this to launch a tool or search on property or attribute. 4. Undo (shortcut Ctrl Z) 5. Redo (shortcut Ctrl Y) 6. [Saving state](/documentation/qonic-dashboard/models/model-version-management.md) of the currently active model, including a publish button which closes the application and takes you to the [model version history](/documentation/qonic-dashboard/models/model-version-management.md), where you can choose to publish or discard you changes. 7. Notifications button. 8. Options button to open the model in the desktop/browser or return back to the [dashboard](/documentation/qonic-dashboard/dashboard-overview.md). 9. [Inspect Panel](/documentation/qonic-application/querying-and-reporting/inspect-panel.md): use this panel to inspect the attributes, properties and relations of one or more parts. 10. [Libraries Panel](/documentation/qonic-application/querying-and-reporting/libraries-panel.md): use this panel to manage and get an overview of your library items in the currently opened model(s). 11. [Issues Panel](/documentation/qonic-application/querying-and-reporting/issues-panel.md): use this panel to create, assign and comment on issues in the currently opened model(s). 12. **Hide or isolate** elements. Select the entities you wish you hide/isolate, click the eye icon in the navigator, and click to *Set As Scope* + or *Remove From Scope* -. If a scope is active, you can *Reset Scope* \*. 13. Activate a **section plane** Ctrl Shift E **or section box** Ctrl Shift X. Either manually create a temporary section plane/box in any direction or activate a plan section or elevation based on the story/level information in the model. A green notification dot indicates that a section plane is currently active. 14. [Views Panel](/documentation/qonic-application/querying-and-reporting/views-panel.md): use this panel to create saved views and jump between these views easily. Jump to one of your favorited views (up to 5 views can be set as favorite) by using shortkeys 1 to 5. 15. Toggle visualization of 3D [Spaces](/documentation/qonic-application/basics/visualisation-settings/spaces.md) 16. Toggle visualization of building [Grids](/documentation/qonic-application/basics/visualisation-settings/grids.md). 17. Toggle visualization of the [Survey Point](/documentation/qonic-application/basics/visualisation-settings/survey-point.md). 18. [Browse Panel:](/documentation/qonic-application/querying-and-reporting/browse-panel.md) use this panel to browse your model. Group and filter on location, IFC Class, IFC Properties and other attributes. 19. [Report Panel](/documentation/qonic-application/querying-and-reporting/report-panel.md): use this panel to generate reports of quantities and properties. 20. [Planning Panel](/documentation/qonic-application/querying-and-reporting/planning-panel.md): use this panel to create and visualize construction sequences. 21. Help Center: contains actions like opening the tips panel, sending a message to the Qonic team, reporting an issue, booking a demo, or visiting external links like the help center or [community](https://community.qonic.com/). 22. [Modeling and Drafting](/documentation/qonic-application/modeling.md) toolbar 23. [Measuring, geometry and data analysis](/documentation/qonic-application/analysing.md) tools 24. Toggle [Deep Select](/documentation/qonic-application/basics/navigation-and-selection/selection-modes.md#deep-select). Use this to select subentities like edges, faces and vertices. 25. Toggle [Snapping](/documentation/qonic-application/modeling/snapping.md). 26. Toggle the Sketch Grid. This grid allows you to snap to intervals which scale up or down depending on your zoom level.
