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:
AutoCAD Script to Create Classic Workspace Automatically
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”.
