"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you want to maintain DWG compatibility between 2016, 2015, and 2011... start by setting on the 2016 and 2015 stations: Options > Open and Save. From the list, choose: AutoCAD 2010
