Navisworks detects clashes. ClashFlow manages their resolution. The difference is operational: Navisworks produces a list of geometric conflicts. ClashFlow takes that list (or runs its own detection on model check-in), eliminates duplicates, applies project-specific filtering and prioritization rules, assigns each clash to the responsible engineer, tracks the full resolution workflow, verifies fixes against updated models, and generates audit-ready reports. On a recent gas processing facility project, this operational layer reduced clash resolution time by 80%.
