The add-in version 1.2.0 is accessible from a Revit® project and can be used on versions 2021, 2022, 2023, 2024 and 2025.
It can be a new project or an existing one.
The type of project has no influence on the use of the add-in; only the presence of families for the categories to be detected needs to be checked.
Once the project has been created, the level hierarchy must be established so that automatic recognition can be performed on each level.
