Syncing Revit to Blender

6. Syncing Revit to Blender

Once the connection is set up and a license is active, you can sync your Revit model to Blender. There are three ways to do this: syncing all changes, syncing selected elements, and using LiveSync.

Sync operations are queued per document and processed in order. If you trigger multiple syncs quickly, they are handled one at a time. The Revit status bar shows progress messages throughout.

6.1 Syncing all changes

Click Changes in the Sync panel.

Use this when you want to push all recent edits in Revit to Blender. BlenderSync checks which elements in the sync view have changed or are missing from the last known state, and sends those to the server.

When to use it: After making a set of edits in Revit that you want to appear in Blender. Also useful after the first sync, or after a reset.

The status bar shows progress while the sync runs. The sync runs in the background — you can keep working in Revit.

6.2 Syncing selected elements

Click Selected in the Sync panel.

Use this for targeted updates. BlenderSync resolves your current Revit selection to root elements and sends only those to the server. This is faster than a full sync when only a small number of elements have changed.

Before clicking Selected: select the elements in Revit that you want to sync. You can use any standard Revit selection method.

If nothing is selected when you click Selected, the status bar shows:

Select one or more elements in <document> to sync them.

No error is shown and nothing is sent. Just select something and click again.

Selected resolves to root elements — for example, selecting a face of a wall sends the whole wall, not just the face.

6.3 LiveSync

Click Start in the LiveSync panel.

LiveSync watches your Revit document for changes and sends them to the server automatically as you work. The Start button is replaced by Stop while LiveSync is active — only one is visible at a time.

To stop LiveSync: click Stop.

When LiveSync stops automatically: - A sync request fails to reach the server (transport failure) - Your license is invalidated while Revit is open

The status bar shows a message when LiveSync stops, indicating the reason.

Use LiveSync intentionally. It reacts to every document change event. On large or complex models, this can generate significant server traffic. Start it when you are actively iterating and stop it when you are not.
