I actually have the same question. Are there any properties of label indicate the associated element name/Id? Or which API can expose the correlation between label and element?

Thanks for the quick reply. Are there any other possibilities for the end user to see the record of his/her modeling process?

Hi, does anyone have any updates about this? Looks like Archicad encrypt their user log...Can't find any related information from the fast logger page.... https://community.graphisoft.com/t5/Project-data-BIM/Archicad-FastLogger-Files/ta-p/303999
