Getting the following message when I open a DWG file.Incompatible version of AEC objects!With these details...File <(><<)>name.dwg> was last saved with an earlier version of an AEC product. Saving this DWG file will update AEC to a newer version, which is incompatible with the version of the software that have originally created them.This alert is coming up when trying to save...
This file contains ARX objects created from an old version of ADT. These objects will be upgraded to a new version upon file saving. The upgraded objects will become incompatible with the old version from which they were last edited.
Contact the creator before saving.History:Custom objects created by Autodesk's AEC products such as AutoCAD Architecture, MEP, Structure Detailing, Civil 3D, can be displayed in MicroStation with proper object enablers. However, these products evolve with their versions and a version on which a particular object in a DWG file may be outdated to the version of the object enabler installed with the RealDWG library MicroStation uses. It is important to be warned before the objects are upgraded because If the file is opened back in the old version of an AEC product, the product may not recognize these objects because of a version mismatch. There is no way to restore the old object format so the old version of AEC product can open the upgraded file properly.Solution:If it is likely that whomever created these objects will need to continue to work on this file, it is highly advised to check with them to be sure this update to the objects will not be an issue before updating the file.To prevent the alert:If these files need to be processed in a batch, the need to suppress the alert is needed.In your configuration, set MS_DWG_NO_AECSAVE_ALERT=1
Addendum:
For MicroStation CONNECT Edition look for the following variable:
MS_OPENDWGAEC
0: open with alert dialog (default)1: upgrade AEC objects to the current version, no alert dialog2: open DWG as read-only, no alert dialog (MS_OPENDWGAEC)
