In AutoCAD 2007, Autodesk greatly expanded the number of palettes displayed by the Tool palette. As one way to harness many the many palettes, it provided "groups," which lets you group palettes into subgroups. This is done with the Customize command.
To access palettes and groups, you can right-click the mass of tab lines at near the bottom of the Tool palette. But then you still have to chose from a long list of palette names.
Here's a way to avoid the congestion and get right to the palette you need: click the big icon that represents each of the control panels in the Dashboard:
* 3D Make control panel: click the icon to display the Modeling tool palette.
* 3D Navigate control panel: displays the Camera tool palette.
* Visual Styles control panel: the Visual Styles palette.
* Light control panel: curiously enough, displays the Modeling palette, a bug I suppose.
* Materials control panel: shows the the many Materials palettes.
The 2D Draw and Render control panel icons display no tool palettes.
Alternatively, you can right-click the big icon for each control panel, and then select Tool Palette Group from the shortcut menu.
