Understanding NWD Files
NWD files are used primarily within the context of 3D modeling and coordination, particularly with structures and building designs. These files serve as a snapshot of a project that incorporates various elements from different sources, but they are not designed for editing or direct manipulation in CAD environments like AutoCAD.
Can NWD Files Be Opened In AutoCAD?
Directly opening NWD files in AutoCAD is not feasible. The NWD format, developed by Autodesk’s Navisworks, is intended for viewing and sharing 3D models without allowing alterations. This security feature prevents NWD files from being converted to editable formats like DWG or DXF. If your goal includes using the content of an NWD file in AutoCAD, alternative methods must be employed.
Steps to Use NWD Content in AutoCAD
-
Export to DWF: First, open the NWD file in Autodesk Navisworks Manage or Simulate. These versions allow you to export the model as a DWF file, which is more compatible with AutoCAD.
-
Attach DWF in AutoCAD: Once you have exported your model as a DWF, open AutoCAD 2025. Navigate to the ‘Insert’ tab and select ‘Attach’ under the ‘Data’ panel. Here, you can import the DWF file into your AutoCAD workspace.
-
Use External References: DWF files can also be attached as external references (Xrefs) in your AutoCAD project. By doing so, they can be easily managed alongside your other files without altering them directly.
-
Importing FBX Files: For a more detailed approach, you can also export the 3D visual model as an FBX file from Navisworks. This can be imported into AutoCAD via the ‘Import’ feature.
- Check Compatibility: Always ensure that the version of AutoCAD you are using supports the formats you are working with, such as DWF or FBX.

DWF and DWG Comparison
Both DWF and DWG are file formats developed by Autodesk, but they serve different purposes. DWG is the native file format for AutoCAD and allows for full editing of drawings. DWF, on the other hand, is designed for sharing design data efficiently without permitting further alterations, making it suitable for collaborative reviews.
Differences Between NWD and NWF
NWF files serve a different function than NWD files. While NWD is a consolidated version of a model at a specific point in time, NWF files maintain links to the original model files and contain an index for managing these sources. This allows for real-time updates and alterations, whereas NWD files are static.
Frequently Asked Questions
1. What software can I use to view NWD files?
To view an NWD file, you can utilize Autodesk Navisworks Freedom or Navisworks Manage. Both applications are capable of opening and reviewing NWD files effectively.
2. Are there any direct conversion tools for NWD files?
Currently, there are no direct tools available to convert NWD files into formats like DWG or DXF due to the nature of the NWD format being non-editable.
3. Can I view DWF files without AutoCAD?
Yes, you can view DWF files using Autodesk’s Design Review or the free online Autodesk Viewer, making it accessible without needing to purchase AutoCAD software.
