The Ultimate Revit Model Hygiene Checklist

Models collect clutter—unused families, imported CAD, orphaned filters, duplicate types—and it shows up as slow syncs, big files, and graphics crashes. Run this on a cadence and the model stays fast. Skim the table, then the detail.

Diagnose Before You Clean

Don't clean blind—spend two minutes finding the actual problem first:

• File size + trend. A model far larger than peers, or one that jumped suddenly, points straight at imports, runaway groups, or duplicate sprawl.
• Warning count. Manage > Warnings shows the total at the top. A five-figure count is your priority signal.
• Element count. A type-count schedule (Itemize off) reveals categories bloated with near-identical types.

Fix the biggest contributor first; the rest of this list is the toolkit.

Weekly Quick Pass

1. Warnings. Manage > Warnings. Clear high-impact ones first: Duplicate Mark values, duplicate Type Mark, Room separation overlaps, walls overlap. Rule of thumb: keep under ~100 per 100 MB.

2. Close inactive views. Each open view is recomputed on changes—Close Inactive Views before syncing.

3. Spot new duplicates. Catch fresh Copy/-1 types in the Browser before they spread.

Monthly Deep Clean

4. CAD imports. Manage > Manage Links > CAD Formats. Remove orphans; link, don't import; never explode (it converts every line to a native element); keep reference CAD in drafting views.

5. Purge. Manage > Purge Unused, 2–3 passes—parents free children each pass. Don't purge template content meant to stay available but not yet placed.

6. Consolidate duplicate types. Use Rename Pro's rule-based duplicate detection to find types that resolve to the same name—even when their current names look unrelated—then merge and rename. Full procedure: How to Clean Up Duplicate Revit Families and Types.

7. Cull unused graphics assets. Delete unused view templates, filters, line/fill patterns, and materials—they pile up from copied views and imports and clutter every dropdown.

8. Naming audit. Run a full rename pass; the Name Previews panel shows current vs. proposed side by side, so drifted types stand out and one click corrects them.

Quarterly / Milestone

9. Audit on open. Open the central model with Audit ticked (on a local copy—it's slow) to catch low-level corruption early.

10. Worksets & links. Confirm worksets stay logical (Shell, Core, Interiors, Linked Models) and links load by relative path.

11. File-size trend. Track size over time; a sudden jump usually means an exploded import, a runaway group, or a flood of duplicates—trace the spike.

12. Groups & in-place families. Replace repeated in-place elements with loadable families; don't nest groups in groups.

Hygiene is cheaper as habit than as cleanup. Put this cadence in the BIM coordination calendar, not the deadline week—and when the model still feels heavy after a clean, move on to Revit Performance Tips for Large Scale Projects.
