Ungroup Detail Groups (Revit pyRevit Tool)

Break detail groups apart and clean up the leftover types in one pass.

Detail groups are convenient until you need to edit annotation locked inside them across an entire model. This pyRevit tool explodes every detail group instance back into individual elements, then deletes the detail group types that are no longer placed.

What's inside

• One pyRevit button: Ungroup Detail Groups
• Detection of all detail group instances and types in the model
• A two-step operation: explode instances, then purge unused types
• Safe handling of types with dependents (skipped and reported, not force-deleted)

Who this is for

• BIM professionals reworking annotation that was trapped in detail groups
• BIM managers cleaning a model before handover
• Revit users transitioning into BIM who want a safe, reviewable ungroup pass

Requirements

• Autodesk Revit 2021 or newer
• pyRevit installed (free, from pyrevitlabs.io)
• Runs in a single confirmable, undoable Revit transaction

What you'll get faster

The slow job of selecting and exploding detail groups view by view. One click handles the whole project and tidies up the unused types.
