=== Organizing Objects in Color Groups ===
[[Image:cad_manual-0_new.png|thumb|360px|CubeCAD's Navigation Tree.]]
CubeCAD's Navigation Tree groups and organizes objects using a hierarchical system. Located at the top of the Navigation Tree and under the CubeCAD icon are two main groups: '''Geometrical Construction''' and '''Data Visualization'''. Under Geometrical Construction, you create or import and manage CAD objects. Under Data Visualization, you create or import and display 3D representations of real, complex, scalar or vector data in a variety of formats. The Data Visualization group and its usage will be discussed later in this manual. The next sections of the manual will present a detailed discussion of CAD objects, their creation, transformation and management.
