=== 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 structureparameters, 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 the toolbars, you can undock, move around or hide the module bar and navigation tree.
The contents of the navigation tree vary depending on the selected module. In [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]], the navigation tree features two main sections: Geometrical Construction and Data Visualization. The "Geometrical Construction" section holds your geometric objects, while the "Data Visualization" section is used for generation of 3D data visualizations to be displayed in the project workspace. In other modules, the navigation tree typically features five distinct sections:
