What does ModelPurgePro do?

Finds purge candidates and duplicates, verifies context, and purges selected items safely.

Unused content detection

Scans views, templates, filters, scope boxes, groups, links, CAD, images/PDF, and more.

Duplicate rules

Detects duplicate model and annotation elements with rule-based matching.

Verification-first cleanup

Reveal before delete, batch purge, warning suppression, and Undo-friendly execution.

Workflow

Minimal steps. Maximum clarity.

1) Choose source

Analyze active model or a loaded Revit link.

2) Enable targets

Run only checks you need for faster iterations.

3) Reveal and act

Validate candidates, then purge selected or export to Excel.

How to use ModelPurgePro

In 5 steps.

  1. Run DiFlow > Model Cleanup > ModelPurgePro
  2. Choose source (active model or loaded link)
  3. Enable targets to scan only what matters
  4. Review candidates with search and filters
  5. Reveal, then purge selected items (or export to Excel)

Compatibility & notes

Behavior depends on source type, target selection, and model scale.

Linked models

Analysis and export can run on loaded links. Purge is restricted to active document.

Protected content

Sheets and placed views are protected from purge actions by design.

Large models

Streaming collectors and batching are optimized for scale; duplicates can be heavier.

What exactly does ModelPurgePro do?
It finds safe-to-remove candidates (unused management items, orphaned types, imports, and duplicates), lets you review them, and purges what you select.
How do I use it in the fastest way?
Enable only the targets you need (for example Views, Templates, and Filters), use Search, verify candidates, then run Purge Selected.
Does it delete sheets or placed views?
No. Sheets are excluded, and views placed on sheets (including schedules and panel schedules) are protected.
The candidate list is empty. Why?
Common causes:
  • No targets enabled
  • The selected source is a link that is unloaded
  • There are genuinely zero candidates for selected targets
  • Filters hide results (Unused only and Search text)
Can I verify items before deleting?
Yes. Select candidates and use Reveal in Revit to jump to the most relevant context.
Can I undo what it purges?
Yes. Purge operations run inside Revit transactions, so Ctrl+Z works subject to Revit normal undo limits.
Does it slow down large projects?
It is designed for large models with streaming collectors, early-exit loops, and batched operations. Duplicate detection can be heavier than unused-type checks, so run duplicates only when needed.
Worksets: what happens when deleting a workset?
Empty user worksets are detected. When deleting selected worksets in a workshared model, elements can be moved to a fallback workset based on Revit standard behavior.
What does the Excel report include?
One worksheet per target, with columns: Id, Name, Type, Used, Reason.
