Sometimes while doing our job in AutoCAD there is some instances that happens unexpectedly. And one of that is the accidental turning off of the command line, and with that, you are unable to see the command that you’re keying-in.
There is two way actually to hide the command window of AutoCAD or in these case to unhide. One of these is on the keyboard shortcut, by pressing CTRL+9. The other is at the Tools pulldown menu, then Command Line (fig.1). Alternatively if you are using AutoCAD Architecture 2008 and beyond, you can find the command line in Window pulldown menu as well (fig.2).
Thats all for now.
