Revit 2026 gives you good interoperability options, but it still doesn’t change the FBX limitation: you’ll route InfraWorks context through FBX → DWG/IFC, then link that into Revit.
1. InfraWorks → FBX export (site context)
In InfraWorks 2026:
- Turn on only the feature classes you care about (terrain, roads, buildings, major structures) so you don’t overload Revit with detail.
- Use Export 3D Model, pick FBX (entire model or a specific model extent), and make sure coordinates are left in the original system (no re-centering), since you want them to line up with survey/Revit.
2. FBX → DWG (or IFC), preserving coordinates
With Revit 2026, the cleanest path is still via another app:
- Open the InfraWorks FBX in 3ds Max, AutoCAD with FBX import, or a converter like CAD Exchanger and export to DWG or IFC while keeping world coordinates.
- For infrastructure, DWG is usually simplest for terrain/roads; IFC can be helpful if you want some object-level structure for buildings and structures.
3. Link into Revit 2026 as context
In your Revit 2026 model:
- Use Insert → Link CAD for DWG, or Insert → Link IFC for IFC, and choose positioning based on how you exported (Internal Origin vs Shared Coordinates; IFC links in 2026 are faster and have improved positioning controls).
- Pin the link, put it on its own workset (e.g., InfraWorks_Context), and keep it off in documentation views; treat it as read-only visual and coordination context.
