Bird Tools - Automatic Tag Stacker

Digitally signed app



Bird Tools - Automatic Tag Stacker” is an Autodesk® Revit® Add-On that aims to stack identical TAGS above each other while maintaining the leaders separately, thus forming one multileader entity as in Autodesk® AutoCAD®.


The user is given a choice between straight leaders, “dog-legged” leaders (leaders with elbows/landing lines), and a match leader mode, where the tags are stacked based on an already existing tag. It proves to be extremely helpful in areas that are overpopulated with tags and thus help the user reduce the space occupied by some of these tags by stacking the ones with identical contents.


Revit 2017-2018-2019-2020-2021-2022-2023-2024 and 2025 editions are all supported.


Note: This app uses a custom installer (and not the standard Autodesk App Store installer).

    If this could be modified so it could stack multiple tags into a column as well, it would be the go to plugin for arranging tags
