How to View NWD File in AutoCAD

Understanding NWD Files

NWD files, or Navisworks Document files, are specialized formats used primarily for 3D model visualization and project collaboration. These files contain intricate details such as geometry, object properties, clash tests, and viewpoint information, making them essential for professionals working in architecture, engineering, and construction (AEC). However, direct compatibility between NWD files and AutoCAD formats is limited, leading to specific steps for viewing them in AutoCAD.

Prerequisites for Viewing NWD Files in AutoCAD

Before attempting to view an NWD file in AutoCAD, ensure you have the following:

• AutoCAD 2025 installed on your computer.
• Navisworks Manage or Simulate (for conversion).
• A suitable converter or intermediary format like DWF to facilitate the file exchange.

Method 1: Exporting NWD from Navisworks

To view an NWD file in AutoCAD, the first step involves exporting it to a compatible format using Navisworks. Here’s how to do this:

1. Open the NWD file in Navisworks Manage or Simulate.
2. Select the ‘Export’ option from the File menu.
3. Choose ‘DWF’ or ‘DWFx’ as the output format.
4. Designate the destination folder and provide a name for the exported file.
5. Click ‘OK’ to complete the export process.

Method 2: Importing DWF into AutoCAD

Once you have your DWF file, you can easily open it in AutoCAD. Follow these steps:

1. Launch AutoCAD 2025 on your computer.
2. Go to the ‘File’ menu and select ‘Open’.
3. In the ‘Files of Type’ dropdown menu, select ‘DWF’.
4. Navigate to the folder where you saved the exported DWF file and select it.
5. Click ‘Open’ to load the file into AutoCAD.

Alternative Method: Using FBX for Compatibility

If you prefer to use FBX format, which is also supported in AutoCAD, here’s how to convert NWD files:

1. In Navisworks, open the NWD file.
2. Select the ‘Export’ option and choose ‘FBX’ format.
3. Initiate the export process by selecting the desired destination.
4. Open AutoCAD 2025.
5. Go to the ‘Insert’ tab and select ‘Import’.
6. Choose the FBX file from your local storage and click ‘Open’.

Viewing in AutoCAD: What to Expect

Once the DWF or FBX file is opened in AutoCAD, you will have access to the model along with its properties. Keep in mind that NWD files encapsulate a lot of data, so the visual fidelity may vary based on the complexity of the original model and the limitations of the conversion process. You can manipulate the model, measure dimensions, and use AutoCAD’s tools to further analyze the design.

Frequently Asked Questions

1. Can I directly open an NWD file in AutoCAD without conversion?

No, AutoCAD does not support direct opening of NWD files. Conversion to DWF or FBX is necessary.

2. What tools are required for exporting NWD files?

You will need Navisworks Manage or Simulate to perform the export successfully.

3. Is there a way to view NWD files without AutoCAD?

Yes, Navisworks Freedom can be used to view NWD files directly without any conversions.
