Model Tree (Navigation Panel)
Click the Model tree icon in the 3D toolbar to see and work with the structure of a 3D object. The model tree is displayed in the Navigation Panel and shows the element hierarchy (nodes, groups, individual objects). Right-click a member of the hierarchy for viewing and export commands.
Click the Options button at the top of the Model Tree panel to specify display options, color settings, render mode, or to export the whole tree into an XML file.
XML files are ideal for data distribution because they are easy to port and their display can be specified through style sheets.
