Recently i have been building some interesting things and one of them is archiXML an online attribute editor now integrated directly in Archicad via Tapir.
ArchiCAD native attribute manager is good but some tweaks take long to do and this tool saves you some time.
It is free the link is: https://www.architools.net/archixml
Features such as attribute reindexing in bulk, bulk renaming, adding prefixes, bulk changing colors and pen thickneses, project info data, there is Layer filter a new feature to interactively change and see the layer combinations and states of layers inside them with edit option to hide/show/lock/wireframe layers in the combinations, new features Compare two ArchiCAD files and copy attributes from one to another almost all attributes can be copied between files by selecting each you like from your template to another file for example, purge unused for layers/zone categories, Find & replace names across all attributes in single click. Option to create layouts and subsets in bulk at once (empty for now soon will add feature to also add drawings on them automaticaly). Also works with exported xml files from ArchiCAD and importing them back changes your file.
Of course, this is a feature only advanced users - BIM Managers should play with, not intended for everyday working files, except when you know what you are doing.
