Preparing a Revit file to export to the Navisworks file format

on

To get a model going in Navisworks, you'll need to start in your design software of choice.  Typically this is Revit or AutoCAD, although other software can be used.


This example will use Revit as the design software.  Open your model in Revit.  It is a good idea to go to the 3D view.  Remember that Revit will export to Navisworks specifically what you have shown in the a view.  The 3D view is the best place to do this.  In order to get a model out in a format Navisworks can read you need to utilize object enablers under the Add-Ins tab.  Click on the External Tools button.

Once you select External Tools, you can pick the Navisworks 2015 button.  This will open an export scene as dialogue box where you can save the 3D view in a Navisworks file format.

In this dialog box there is a button called “Navisworks Settings” which you can use to adjust settings to your liking.  One thing that makes Navisworks so powerful is the fact that it can work with a variety of different file types.   Below is a list of the file types available.  Navisworks is capable of working with typical linework from CAD programs, 3D models, and Point Clouds.

Starting a Navisworks Model.

To create a Navisworks model you will need a model created in another software such as Revit or AutoCAD.  This model, once exported will be either appended or merged into the Navisworks file.  The Append command can be found under the home tab.  To access the merge command click on the small arrow below append.

What is the difference between the Append and Merge model commands?  If you have errors in your models, merge will eliminate duplicates in your models by overriding the previous model.  In practice it is better to append because it forces you to keep clean models in your design software.  This is where you’ll import your various models of the building.  Below is a suggested method for breaking the models up. I typically append my models when I receive them from consultants.

  • Architectural Model
  • Electrical Model
  • Structural Model
  • Mechanical Model
  • Sprinkler Model
