Revit Tools by Avant Leap

Variato

Model Comparison Analysis

Revit add-in that tracks and visualizes parameter changes across model versions. It enables BIM managers and coordinators to identify what changed between model states, comparing element parameters, geometry modifications, and type properties, without manual inspection or external diffing tools.

Modern architecture visualization and building model

Principal Uses

  • ✓Audit model versions - detect parameter/type/geometry changes
  • ✓ QA/QC handoffs - verify authorized edits only
  • ✓Resolve federated conflicts - track discipline overlaps
  • ✓Evaluate design options - compare cost/performance metrics

Frequently Asked Questions

Find answers to common questions

Yes, Variato reads model data via the Revit API, so as long as both models open in your current Revit session (via upgrade if needed), comparison works. Note: Revit auto-upgrades files, so always keep backups of legacy versions.
Both. Variato flags parameter differences AND geometric modifications (location shifts, profile edits, rotated elements). You choose which change types to include in the comparison filter.
Variato supports category filtering and view-based comparison, compare only structural columns, or only elements visible in the current view. This keeps reports focused and processing fast.
Absolutely. Variato generates: - Excel tables - PDF reports - CSV logs (for integration with other QC tools)
Variato 1.0.0 requires Windows 10 or 11 (64-bit).
