In both AutoCAD and Civil 3D the command line is still amongst the most important tools available to a user, as it offers prompts through out commands, gives access to sub commands and more. However, if a user accidentally loses their command line, panic can quickly start to set in.
Fortunately restoring the command line is simple, either use the drop-down menu beside pallets on the home tab (Fig 2), or use the keyboard shortcut Ctrl+9.
