The 2018 release of Revit gives us the ability to import a Navisworks coordination model. And that means we can now bring our InfraWorks model into our Revit model for complete collaboration. Here’s how to do it.
Start by exporting a portion, or the entire InfraWorks model, to a 3D model. Click on SETTINGS & UTILITIES > EXPORT 3D MODEL. In order for the model to maintain its geographic location, you must set a User Defined Offset of 0,0,0 prior to exporting to FBX format.
Open the FBX model in Navisworks. The units of the Navisworks model must match the units of the FBX exported from InfraWorks. To change the units in Navisworks from the Selection Tree select the model, right-click and choose Units and Transform. Verify that the X, Y, Z coordinates are the same as in Step 1.
Save the Navisworks model as an NWD coordination model.
Geolocate the Revit model by acquiring the coordinates of a site plan DWG that has the same coordinate system as the InfraWorks model. A good way to ensure your site plan DWG and InfraWorks model have the same coordinate system is to open the InfraWorks model directly into Civil 3D.
Link the coordination model from Step 3 into the Revit model using the Origin to Origin option.
You can now view your Revit 2018 model within the context of your InfraWorks 2018 model using Navisworks 2018 to create an NWD coordination model.
