Auto Sync functionality has been added to the Twinmotion drop-down menu.
When enabled, Auto Sync supports automatic synchronization of changes from the active Revit model to the direct link connection in Twinmotion or Unreal Engine. A 3D view needs to be active in order to enable Auto Sync, which is then associated to that 3D view.
Once Auto Sync is enabled while in a 3D view, all visible geometry in this view is automatically kept in sync.
