“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 to 2026 editions are all supported.

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