AEC objects in mechanical 2012

[AllanDam]

Hi, I am used to Autocad Architecture and using AEC walls. Now I got Autocad Mechanical and when I open a drawing with AEC walls they are completly dumb. Is there no way that I can use these elements in Mechanical?
Thanks!

Is it AutoCAD Mechanical? Or AutoCAD MEP?

It is AutoCAD Mechanical 2012

Ah, I see. I wasn't aware that AutoCAD Mechanical contained AEC objects, especially the tools from AutoCAD Architecture.

Sorry, I'm an AutoCAD MEP guy, not Mechanical. Sometimes people confuse the terminology so I won't be of much assistance since you're using Mechanical and not MEP.
