If a load was applied improperly, or if certain heavy elements (like mechanical equipment) were omitted, the mass summary table will immediately show anomalies. A sudden spike or drop in mass between adjacent stories is a major red flag that usually requires troubleshooting.

For large models, raw data is overwhelming. Export the Mass Summary to Excel and run these checks:
