DWG version 2018 (compability AEC objects)

[hanslammerts]

Hi,

I tested DWG back and forward from version 2018 to 2013 and vice versa.

With the BUDWEISER files http://www.cadstudio.cz/budweiser

Opening a 2013 DWG file in AutoCAD 2018 will show these correct

Opening a converted 2018=>2013 DWG file in AutoCAD 2017 or earlier will show "PROXY" without the correct display. See att.

So for working in a team with part of the members working with verticals like Civil3D, Architecture, MEP it seem there is something to concider.

AEC object definitions saved in AutoCAD 2018 cannot be made visible again with current objects enablers in older versions. Am i right?

In this respect i was thinking what in what format recovery files are being stored? Is this the same formats as in the options 'open and save' can be choosen. I was think about the senario that it will save Civil3D files accidently by default to 2018 and there is no way back to use as xref in other AutoCAD / Autodesk products...

Regards Hans

Messing up data / apps is 'core business'. You dont have to be an expert to see that, Just look at AutoCAD dev.

It can be good, it can turn out ugly.
