Q - question

ARX_ERROR: eNotThatKindOfClass, or eDuplicateKey

A - answer These ARX errors can occur when trying to open a DWG file containing new type of objects (objects coming from a newer version).

If you are opening a .DWG file saved by AutoCAD 2007 family product (saved as 2004-format DWG) in AutoCAD 2006, 2005, or 2004 (or AutoCAD-based application), apply the appropriate AutoCAD 2007 AEC Object Enabler fix.

These Object Enablers for versions 2010, 2009, 2008, 2007, 2006, 2005 and 2004 are available on www.cadstudio.cz/download.
