2026.3 Release

Important Information

Revit 2026.5 introduces updates based on .NET 10, including releasing Revit Core Engine (RCE) 2026.5. Navisworks 2026.3 requires RCE 2026.5 or later. If you update to Navisworks 2026.3, you must also update RCE to avoid failures when opening Revit and IFC files using conversion methods v2 and v3 (NW-63177).
