Getting your first model live takes under a day. Most of that time is spent on Revit export preparation — not on the upload itself, which is typically complete in under two hours for a standard commercial project. This guide walks through everything from export settings to sharing your twin with stakeholders, so you know exactly what to expect at each step.

The most common cause of upload issues is skipping the model prep checklist. Five minutes of pre-export review saves hours of troubleshooting. Start here.

Before you export: model prep checklist

• Confirm levels and rooms are named consistently — inconsistent naming creates parsing errors in the twin
• Purge unused families and links to reduce file size and processing time
• Check the Coordination Model for unresolved clashes that may create geometry issues in the export
• Set shared coordinates if working with a federated model — this ensures disciplines align correctly in the twin
• Confirm all sheets are on the correct phase — phase mapping affects what elements appear in each level of the twin

Exporting from Revit to IFC

Use the built-in IFC exporter in Revit 2022 or later, or the open-source IFC for Revit plugin for earlier versions. The key export settings are: IFC2x3 or IFC4 schema (both work; IFC4 is preferred for new projects), export rooms as IfcSpace elements, and include property sets — these carry the data attributes that populate the asset register in the twin.

If you're working with a federated model where architecture, structure, and MEP are separate files, export each discipline separately. WeReno accepts multi-file uploads and federates them within the twin. Do not attempt to merge disciplines in Revit before export — the merged file is typically larger, slower to process, and harder to update when discipline models change.

Uploading to WeReno

1. Create a project in WeReno and enter the project address — this sets the geo-location for the twin
2. Drag and drop the IFC file (or files) into the upload panel — the pipeline starts automatically
3. WeReno parses rooms, levels, and systems from the model data — no manual tagging required for standard exports
4. Review the zone map and confirm that room names match your project schedule terminology
5. Assign trade schedules to zones — this links your construction programme to the spatial model
6. Activate stakeholder access and send invite links to your team and clients

Going live

Once the upload is processed, your twin is live and shareable. The link requires no software installation — clients and subcontractors access it in any modern browser. On a typical commercial project, processing takes 45–90 minutes depending on file size and complexity. You'll receive an email when the twin is ready.

Common issues and how to fix them

• Rooms not parsing — Ensure rooms are placed and bounded in Revit before export. Unplaced rooms don't export as IfcSpace elements.
• Missing levels — Check phase mapping in the IFC export settings. Levels on inactive phases may be excluded from the export.
• Geometry errors — Run Revit's IFC export health check before uploading. Most geometry errors come from unresolved warnings in the model.
• Large file upload timeout — For federated models over 800MB, split by discipline and upload separately. WeReno federates them automatically.
