Revit Tip: Compact Revit Central to Reduce File Bloat

Keep your workshared model fast and stable: regularly Compact the Central and apply a few maintenance habits to reduce file bloat, rebuild indexes, and cut Sync with Central times.

Why compacting the Central matters

• Rebuilds and defragments the RVT database, often reducing file size.
• Improves Save/Synchronize performance by cleaning internal indices.
• Lowers risk of corruption from long-running sessions and heavy editing.
• Pairs well with Purge, Resolve Warnings, and link cleanup for a lean model.

When to do it

• After major deletes, large purges, or phase changes.
• Following upgrades to a new Revit version.
• Weekly/biweekly on large teams or long-lived projects.
• When Sync with Central slows noticeably or locals grow very large.

Pre-flight checklist (file-based worksharing)

• Notify the team; schedule a short maintenance window.
• All users: Synchronize with Central, Relinquish All, and close Revit.
• Archive a copy of the current Central and critical links.
• Confirm you have exclusive access to the Central file location.

How to compact the Central (file-based)

• Open the Central RVT with:
  • Detach from Central = ON (Preserve Worksets).
  • Audit = ON.
• Once open: File > Save As > Project.
  • Options: check “Compact File.”
  • Set backups for Central (10–20 is common).
  • Save over the existing Central or save as a new Central (recommended for safer rollback).
• Close the model. Instruct all users to delete old locals and create fresh locals from the updated Central.

Cloud worksharing (Autodesk Construction Cloud/BIM 360)

• Platform services handle much of the compaction. If performance degrades:
  • Open a recent local cache, Detach from Central, Audit = ON.
  • Save As Cloud Model to the same project (new name), then have the team create new cloud locals.
  • Archive or retire the prior cloud model.

Extra model-health actions to pair with compaction

• Purge Unused (in stages), then compact.
• Resolve critical warnings (especially constraints and highlights that impact regeneration).
• Unload or remove stale links; verify shared coordinates are correct.
• Clean up Design Options, Worksets, and large groups.
• Review imports; replace heavy CAD with curated links.

Common pitfalls to avoid

• Compacting while anyone is connected to the Central.
• Skipping Audit on long-running, complex projects.
• Reusing old locals after the Central has been compacted/rebuilt.
• Saving with too few backups for the Central.
