In your drawing are informations of older and/or newer Versions of AEC-Stuff = special Object data from vertical versions which are not plain AutoCAD or LT)

(or you only save the file to an older File-Version)

What product are you running? (Screenshot of dialog ABOUT)

Hi @kinman_cheung,

As @cadffm explained, there are objects in your drawing and possibly in your templates that came from a vertical product or toolset and possibly came from different versions.

I suggest that you install any applicable object enablers and then consider an performing an exporttoautocad.

You are welcome to attach one or more of your drawing files to a post so I can take a closer look.

Hi,

 An appropriate object enabler is not installed to support the AEC objects.

Do one of the following:

1, Use the -EXPORTTOAUTOCAD command (or AECTOACAD) to resave the file.

2, Install the needed object enabler.

3, Open the file in the newer version of AutoCAD which last saved it.

4, Use AutoCAD Architecture to open Architectural Desktop files, or revert to Architectural Desktop itself.

5, In AutoCAD Land Desktop, use the Format/Explode setting in the Civil Batch Drawing Converter utility to resave the file.

I believe it helps on my problem, but I need to wait for our IT admin. to install the latest AutoCAD version on my pc.
