Tool palettes provide convenient access to a variety of tools and content. Tool palettes are a standard feature in AutoCAD. You can open tool palettes using the ToolPalettes command, or from the ribbon.
Tool palettes provide access to both AutoCAD and Autodesk Civil 3D tools and content. For example, the Autodesk Civil 3D tool palettes provide access to subassemblies and assemblies that you can use in corridor design. They also provide access to civil engineering related render materials and multi-view blocks.
You can drag and drop an item from a Tool Palette into the drawing to insert it. Any prompts that are required for inserting the item are displayed at the command line.
