AutoCAD Architecture 2013, Don’t Look Back!

In the Autodesk world, DWG versions stay the same for three years. For instance 2010, 2011 and 2012 wrote the same DWG version it was called the 2010 version DWG.

Every 4th release historically has been a file format release and 2013 is no different.  For AutoCAD users, this is no big deal. One can always open the previous version and in plain vanilla AutoCAD they can save down to almost any previous version DWG.

When AutoCAD Architecture, or ACA, users save their files in 2013 and then save back to an earlier version to share with consultants or clients, those using a previous version of ACA can no longer edit the AEC objects as intelligent objects. The intelligent Doors walls and windows, for example, cannot be saved down to the previous version and maintain their intelligence. Upon opening the older DWG in AutoCAD Architecture they will get the following error.

Don’t save . . . or else

 

 

 

 

 

 

 

This means that the smart objects will be upgraded and not intelligent if downgraded to older DWG formats. Downgrading will make these objects dumb and not editable.

Users will not be able to change a simple door width for example. Also, we have seen users getting a ton of errors when opening a DWG that has been saved in a version of AutoCAD Architecture that writes a newer version DWG. for instance; “ARX error — e not of that class”

Options / Workarounds;

  1. Don’t look back. Save all DWGS in the current versions and ask your consultant to upgrade. 😉
  2. “Export to AutoCAD”  Command: _AECEXPORTTOAUTOCAD2010 Loading AEC Object Explode… This will explode all AEC objects to linework and blocks.

Hopefully, you find this article before you upgrade your entire ACA project to the newest release. If not hopefully your not using AEC objects. Hopefully, you will consider Revit.

Please comment or give me a call if I can be of assistance or if there are any other questions or concerns.
