How to turn off the Start Tab in AutoCAD

Change the STARTMODE system variable.

1. Type STARTMODE on the command line in AutoCAD.
2. Enter 0 (zero) to turn off the Start tab or 1 to turn it on.

Turning it on requires restarting AutoCAD. If you are running AutoCAD in a single document mode (SDI =1), the Start tab will be displayed after you change the value of SDI to 0 and restart AutoCAD.

The Start tab in AutoCAD 2016 replaces the New Tab in AutoCAD 2015 and eliminates the NEWTAB and NEWTABMODE commands.
