=== Navigation Tree ===
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 for [[CubeCAD]], [[EM.Tempo]], [[EM.Terrano]], [[EM.Illumina]], [[EM.Ferma]], [[EM.Picasso]], [[EM.Libera]] and [[RF.Spice A/D]]. 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.
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.
The contents of the navigation tree varies depending on the selected module. In [[CubeCAD]] the navigation tree features two main sections: Geometrical Construction and Data Visualization. The Geometrical Construction section holds your CAD objects, while Data Visualization section contains all the 3D visualization objects which appear in the project workspace. In other modules, the navigation tree typically features five standard sections:
*Physical Structure
*Computational Domain
