Model Positioning & Export Configuration (Revit & Navisworks)

Here are a few good practices to keep in mind when setting up your model coordination workflow to enhance interoperability between Navisworks and Revit, and ensure that you get proper the positioning of the issues published to BIM Track.

You have to use a shared coordinate system for your project. It is mandatory to have it configured in the file reader options within Navisworks (screenshot #1). This setting also has to be enabled in Revit (screenshot #2) when exporting .rvt files into a .nwc format. Ignoring this step will result in inaccurate positioning of the issues recorded by BIM Track.

From Navisworks:

  1. Open the Navisworks menu.
  2. Click the options button. 
  3. Expand the 'File Reader' submenu. 
  4. Locate and set the Coordinates field to 'Shared'.
  5. Import your Revit file and your model should now be properly positioned geographically.


From Revit:

  1. Select the Navisworks 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 Naviworks and your model should now be properly positioned geographically. 


If your workflow relies on IFC, we recommend installing Autodesk's add-in for Revit called IFC 2018 (2017 if you're using Revit 2017, etc.). We have identified a number of issues with Revit's built-in IFC exporter and the IFCSite is not always exported properly if this add-in isn't installed. Which results in odd behavior when you navigate through the model using various add-ins. 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 setting is checked in the IFC export options whether you are using IFC2x3 or IFC4 formats:


As mentioned previously, the add-in provided by Autodesk addresses the various issue with Revit's built-in IFC exporting tool. Here are links to the individual download page:

If you'd like to read further information in understanding how shared coordinates works in Revit, we strongly suggest reading the following article written by Paul Aubin. He is the author of many Revit books and provides an in-deep explanation of how coordinates and project origins work in Revit in comparison to AutoCAD:
