GDL Objects

[Anonymous]

If a GDL Object is created in a higher version of Archicad(example Archicad version 10 or 11) can it be opened in a lower version of archicad (example Archicad version 9 or 8.1)

No.

You should always create the GDL object in the oldest version you wish to use it.
Besides not being backward compatible, the file created in the later version might contain commands, might use Global Variables that were not available in previous versions.

If your script does not use any of the new features of the newer versions you can create a new object in the old AC and cut and pate the script into it. Only problem is you have to redo all the parameters.

You can convert GDL objects from one version of ArchiCAD to another (forwards and backwards) using the LP_XMLConverter tool from GS. This tool converts GDL objects to and from XML. You could, for example, convert AC11 objects to XML using the AC11 version of LP_XMLConverter, then convert back to GDL using the AC9 version of LP_XMLConverter. This tool converts everything - scripts, parameters, other data - but won't do anything to overcome scripting incompatibilities, e.g. new commands. For more info, take a look at this topic.
