For a few years now, AutoCAD has allowed you to migrate your settings forward from an old release to a new one. Since AutoCAD 2006, this has included your custom CUI stuff.
How well is this mechanism working for you? I will keep my opinions to myself for now, but I’m interested in yours. I have added two polls about this (see right) and have more polls on this subject waiting in the wings. Feel free to add your comments here to expand on what you have selected in the polls.
