The command panels are six user-interface panels that give you access to most of the modeling features of gmax, as well as some animation features, display choices, and miscellaneous utilities. Only one command panel is visible at a time. To display a different panel, you click its tab at the top of the Command Panel.
These are the six command panels:
Contains controls for creating objects: geometry, cameras, lights, and so on.
Contains controls for applying modifiers to objects and editing editable objects such as meshes.
Contains controls for managing links in a hierarchy, joints, and inverse kinematics.
Contains controls for animation controllers and trajectories.
Contains controls that let you hide and unhide objects, along with other display options.
Contains miscellaneous utility programs, most of which are plug-ins to gmax.
By default, the command panel appears at the right of the gmax window. You can "dock" them along other edges of the gmax window, or make them a floating window. See Customizing the User Interface.
