Are AutoDesk/CAD concurrent installations possible?

Our environment (rather large public works organization) insists on installing MULTIPLE versions of AutoCad products on the same computer (ex: Autodesk 2017 with 2016 already installed). We have been running on the advice of a single person, that draftsmen/engineers need to have the appropriate software version when reopening/editing drawings. So, in some cases, this had led to having 3-4 editions of Autodesk being installed.

So, has anyone here ever had issues opening older drawings with newer versions? I find it almost impossible to believe that newer versions would have any issues with older drawings.

Yes, sometimes there are incompatibilities when using newer, after editing the file and saving sometimes the file gets corrupt, sometimes it doesn’t save at all, sometimes it messes up the dimensions.

But I have never had major issues regarding opening up an older drawing.

No issues in opening older version drawings on newer version software, but do note that there are some instances of AutoCAD products (Revit, for example) won’t let you save files as legacy versions (i.e. you can’t use “Save As” on Revit 2017 to save a .rvt file that 2016 can open). So in some cases, opening and saving a file on a newer version is kind of a one-way street.

To clarify, I’ve double-checked and it seems AutoCAD still permits legacy saves, so you’ll only really need to worry about this issue with Revit.
