Topic: This application has detected a mixed version of AEC objects...

[alexborodulin11]

How to get rid from annoying message:

"This application has detected a mixed version of AEC objects
participating in this operation.
Newer AEC objects will be disallowed from participating in this
operation." Saving AutoCAD file of AutoCAD block to be inserted in 2000 format doesn't help.
Is there a solution to set AutoCAD to supress this message?

This problem appeared first time maybe 6 years ago and still I cannot find how to resolve it.

If the version you are using to export the file does not support the object, it won't fix it for you. Try using the latest version of Drawing TrueView available for free from
Autodesk to convert to a compatible version.

AEC version is separate from DWG version.  You could have content from a 2012 vertical application in a 2007 DWG format file.  Unlike conventional drawing content, AEC/vertical content does NOT convert down to an earlier version of itself, hence the frequent warnings about upgradig users when using Civil3d, Map3D, and other verticals of AutoCAD.

As I said, saving in older format doesn't work. Critical is - the message, how to supress this message?

[Rob...]

"Save As" does not convert as you stated. You need to either export from the appropriate vertical or use Drawing TrueView to convert the files.

AECTOACAD (from the source app that created the objects) or use TrueView and use the Explode AEC Objects option.

Oh yeah, it's been so long, I forgot about the explode option.

[alexborodulin11]

Explode AEC looks promising. I'll try it.
Thank you,

TrueView 2014, does it have Explode AEC objects option? Cannot find it.
Thank you,

TrueView 2014, does it have Explode AEC objects option? Cannot find it.
Thank you,
Alex Borodulin

If I recall correctly that option doesn't show up until you select a drawing that has AEC objects.

[Rob...]

I don't remember for sure but I think it is the conversion settings. Either that or it does the explode automagically.

TrueView doesn't help (at least on my PC).
Attached drawing was created on old version of AutoCAD (2004), opened in 2014 and saved as 2013 format dwg. Then saved in 2010 format, last step - converted using TrueView to older version (2010).
When attached drawing inserted in AutoCAD 2012, the message "This application has detected..." appears.
Will you have the same message using 2010-2012 AutoCAD?
Thank you,
Alex Borodulin

Here it is fixed. Exported from MEP2013 to 2010.

Finally AECTOACAD worked OK.
Thank you all for your help.
