Contains objects not supported by previous versions

[floorplanz]

Within AutoCad Architecture 2009 how do I determine exactly which objects are not supported by previous versions? The reason - when I export to a previous version of AutoCad I loose the LAYER STATES MANAGER info. And we all know that when you do a save-as, other versions will sometimes change the font.

That only happens if the "other version" doesn't have the same fonts that
your version has. That has nothing to do with "different versions", because
the same thing can happen between two installations of the same version.
I've never had the font arbitrarily change between version if both
installations have the same set of fonts (shx and/or ttf) installed.

Can't help you with layer states - I don't work with that very much.

>>>...which objects are not supported...<<<
Usually items that were not there in the earlier version, PLUS all AEC
content.

what previous version are you taking about exactly?

If you etransmit your file and in the transmital setups pick your file version and "explode all AEC objects" you will not get the ARX errors and you can take all the fonts with you.
