Issue

When you opened a drawing in AutoCAD®, you received one of the following error messages:

• ARX_ERROR: eNotThatKindOfClass
• ARX_ERROR: eDuplicateKey

Solution

The error occurs because the drawings contain objects from the latest version of Architectural Desktop that could not be interpreted with the previous version of the Object Enabler.

Three Object Enabler Hotfixes have been released to prevent these errors:
