Saved an object in AC 10 - now unusable in 9???

[Anonymous]

This is not good. Someone please tell me that there is a method to save objects in 10 and make them usable in 9 and vice-versa.

But you will need the recent versions of the XML converter for downgrading, isn't it? The actual downloadable one will create objects for AC10 (Version 21 or 22 I guess).

There is a version of the converter for every version of ArchiCAD from 8 to 10. Each produces objects suited to its corresponding ArchiCAD version, but the XML source may have come from any other version. For example, I could convert an AC10 object to XML using the AC10 converter, and then convert the XML to an AC8 object using the AC8 converter.
