Edwin Prakaso at the excellent CAD Notes blog has done something that, in hindsight, is blindingly obvious but nevertheless very useful to a multitude of people. He’s written a simple script file that sets up the Classic workspace (or something close to it). It works in any recent AutoCAD or AutoCAD LT. Here’s the blog post:
Edwin uses Microsoft OneDrive to store the script file, so if your workplace restricts access to Cloud storage you might need to download it at home.
I’ve added a reference to this script to my post AutoCAD 2017 – Putting things back to “normal”.
