You can use REDEFINE DSVIEWER to turn it back on, or just enter. The DSVIEWER command appears to be gone, but it’s just hiding. Let’s assume you’ve made the decision to put your environment back to AutoCAD 2008 or earlier how do you do it? I’ve arranged these items in alphabetical order: At least, you have a choice in most cases. We should be grateful that in AutoCAD 2012 at least (unlike some Autodesk products), you do still have that choice. As I stated in my original post, I think you should give any new features a fighting chance before turning them off or ignoring them. One thing that’s regularly asked whenever a new AutoCAD release hits the streets is how to make it work like earlier releases. Much of this post is based on older versions, but there are many additions and differences in this year’s “keep off my lawn” post. As it seems many people find these posts useful, here’s an updated version for the latest release. This is followed by AutoCAD 2010 – Putting things back to “normal”, with AutoCAD 2011 – Putting things back to “normal” not too far behind. The most popular post on this blog, in terms of both hits and comments, is AutoCAD 2009 – Putting things back to “normal”. Edit: If you’re running a more recent release of AutoCAD, have a look at the post AutoCAD 2017 – Putting things back to “normal” instead.
