IFC Export Settings



BIM Track uses the shared coordinates system to place IFC files in the 3D environment of the online viewer. It is possible to import and view multiple IFC’s from the same project at the same time. We strongly recommend installing Autodesk's add-in for Revit called IFC 2018 (2017 if you're using Revit 2017, etc.). We have identified several issues with Revit's built-in IFC exporter and the IFCSite is not always exported properly. This update corrects the issue and provides an enhanced support to export linked Revit file. This add-in will replace Revit's built-in IFC exporting model and won't appear as a standalone add-in.

Once installed, make sure that the following settings are checked in the IFC export options whether you are using IFC2x3 or IFC4 formats. The settings of the Revit project need to be set up accordingly.

With your IFC files exported you’re ready to load them into the online viewer. Details can be found below in the Viewer/Project Tree chapter of this guide.

When exporting your Revit files to Navisworks there are a few similar settings that need to be set:

  1. Select the Revit menu.
  2. Click the 'Export' tab.
  3. Select the NWC format.
  4. Click the 'Navisworks Settings' button at the bottom of the window.
  5. Expand the 'File Reader' submenu.
  6. Locate and set the Coordinates field to 'Shared'.
  7. Import your NWC file into Navisworks and your model should now be properly positioned geographically.
