All the toolbars can be repositioned however you like. Simply grab a toolbar's handle to undock and drag it to any location on the main window. Once undocked, you can also resize a toolbar and make it horizontal or vertical. Move the cursor to the border of the toolbar to turn it into a double arrow. Then drag the mouse until the toolbar gets the right size and appearance. You can dock an undlocked toolbar by dragging and dropping it onto the border of the main window. You can show or hide any [[EM.Cube]] toolbar from '''Menu → View → Toolbars'''.
=== Navigation Tree Module Bar ===
When you start the [[EM.Cube]] application, it lands you first in CubeCAD by default. The Module Bar located on the left edge of the screen is used to switch among CubeCAD and [[EM.Cube]]'s various computational modules. It consists of eight buttons:
Clicking on each of the first seven buttons of module bar changes the view to the selected module. Clicking on the [[RF.Spice A/D]] button, opens the [[RF.Spice A/D]] application if you have a valid license of that application.
=== Navigation Tree ===
The Navigation Tree provides all the details of an entire [[EM.Cube]] project. These include the CAD objects and geometric models, material assignments, computational domain and boundary conditions, mesh structure, source information, observable definitions, etc. Besides the menu bar and toolbars, the navigation tree serves as another place from which you can modify most items in your project. Similar to toolbar, you can undock, move around or hide the Module Bar and Navigation Tree.
