How Do I Convert Navisworks to AutoCAD?

by

Navisworks and AutoCAD are both powerful software tools commonly used in the construction industry. While Navisworks is primarily used for 3D model coordination and clash detection, AutoCAD is widely used for creating detailed 2D and 3D models.

In some cases, it may be necessary to convert a Navisworks file to an AutoCAD file format to further modify or enhance the design. In this tutorial, we will explore different methods of converting Navisworks files to AutoCAD.

Method 1: Exporting from Navisworks to DWG

The most straightforward way to convert a Navisworks file to an AutoCAD-compatible format is by exporting it as a DWG (Drawing) file. Follow the steps below:

  1. Step 1: Open your Navisworks project.
  2. Step 2: Go to the “File” menu and select “Export” -> “Export NWC/NWD/3D DWF”.
  3. Step 3: In the export settings dialog box, choose the desired options such as file location, units, geometry settings, etc.
  4. Step 4: Select “DWG” as the output format.
  5. Step 5: Click on “Save” and choose a location on your computer to save the exported DWG file.

This method allows you to convert your entire Navisworks model into an AutoCAD-compatible DWG file. However, keep in mind that some complex elements such as animations or advanced renderings may not be fully preserved during the conversion process.

Method 2: Exporting from Navisworks to NWC

If you only need to convert specific parts of your Navisworks model, exporting it as an NWC (Navisworks Cache) file can be a more efficient method. Here’s how:

  1. Step 1: Open your Navisworks project.
  2. Step 2: Select the objects or parts of the model you want to export. You can use the selection tools available in Navisworks for this purpose.
  3. Step 3: Right-click on the selected objects and choose “Export” -> “NWC”.
  4. Step 4: Specify the location and name for the exported NWC file.

The exported NWC file can then be linked or appended into AutoCAD using the Navisworks Coordination Model feature. This method allows for greater flexibility as it lets you work with specific portions of your model rather than the entire project.

Method 3: Using Autodesk Recap

If you have access to Autodesk Recap, another option is to convert your Navisworks file through this software. Recap allows you to create point cloud data from laser scans, photographs, or other sources, which can be further processed and imported into AutoCAD. Here’s how:

  1. Step 1: Open Autodesk Recap.
  2. Step 2: Import your Navisworks file into Recap by going to “File” -> “Import” and selecting the appropriate format (NWF/NWD).
  3. Step 3: Follow the prompts and adjust any necessary settings for the import.
  4. Step 4: Once the import is complete, go to “File” -> “Export” and choose the desired output format, such as RCP or RCS.
  5. Step 5: Open AutoCAD and use the “Insert” command to bring in the exported point cloud data.

This method is especially useful if you have complex geometry or need to work with point cloud data in AutoCAD.

Conclusion

Converting Navisworks files to AutoCAD can be done through various methods based on your specific requirements. Whether you choose to export as a DWG file, NWC file, or utilize Autodesk Recap, these methods allow for seamless integration between Navisworks and AutoCAD, enabling you to continue working on your models with ease. Remember to consider the complexity of your model and the desired level of detail when choosing the appropriate conversion method.

By following these instructions, you can efficiently convert your Navisworks files into AutoCAD-compatible formats and further enhance your design workflow. Happy converting!
