Autodesk Architectural Desktop 2007 & Prior

[#1]

Dear All,

 I got some problem in ADT 2007 when I opening the CAD files and  use the command "aecdwgsetup" it reture the error message "not allowed because drawing contains objects from a newer version of this application." Anyone can help to solve this problem ?

Thanks !

The drawing has been saved down from a later version? yes?  

No way to solve it that I know. Just one of those features adesk gives you for free.

yes, the CAD files save from new version ( AutoCAD 2011) .  Autodesk without other method to fix this problem ?

Spoiler

If you are using shortcut icons for the following commands: Fillet, Chamfer, Select Similar you must open your CUI file and edit the macro. Remove the AEC part of the macro line and save your changes.
