How to Import Navisworks File in AutoCAD?

Understanding Navisworks File Formats

Navisworks is a powerful coordination tool widely used in the construction industry, allowing users to combine various 3D models from different software into a single cohesive project. However, the compatibility of Navisworks file formats with AutoCAD necessitates specific methods for importing and utilizing those files effectively.

Types of Navisworks Files

Navisworks primarily uses two file formats: NWD (Navisworks Document) and NWC (Navisworks Cache). The NWD format serves as a snapshot of the project, allowing stakeholders to view and share models. On the other hand, NWC files are intermediary formats created when exporting from various design software. Understanding these formats is crucial for effectively using them in AutoCAD.

Importing Navisworks Files into AutoCAD

While AutoCAD does not allow direct editing of NWD files, it is possible to incorporate these files in a manner that facilitates their use. Below is a detailed step-by-step guide to import Navisworks files into AutoCAD:

Step 1: Prepare the Navisworks File

1. Open Navisworks: Launch Autodesk Navisworks Manage or Simulate.
2. Load Your Model: Open your NWD or NWC file containing the geometry you want to work with.
3. Export to a Compatible Format:
   • Navigate to the File menu and select Export.
   • Choose FBX as your export option, since this format integrates well with AutoCAD.

Step 2: Convert FBX to a DWG-Compatible Format

1. Use Conversion Software: To convert the FBX file to a DWG format, you will need suitable tools like Autodesk Fusion 360 or any other capable conversion software.
2. Open FBX in Fusion 360: Import the FBX file by selecting "Open" and locating your exported FBX model.
3. Export as DWG: In Fusion 360, navigate to the export option and select DWG as your output format.

Step 3: Importing DWG into AutoCAD

1. Open AutoCAD 2025: Launch the latest version of AutoCAD.
2. Access the Import Command: Go to the Insert tab located in the ribbon menu.
3. Select DWG File: Click on Attach and browse to select the newly converted DWG file.
4. Set Insertion Parameters: Adjust settings such as scale and rotation based on your project requirements.
5. Position the Model: Click to place the model in the desired location within your AutoCAD drawing.

Step 4: Finalizing the Import

1. Adjust Layer Settings: Organize the imported elements into layers as needed for better project management.
2. Review the Model: Inspect the imported model for any discrepancies and ensure all necessary components are visible and correctly positioned.
3. Save Your Work: Don’t forget to save your drawing in AutoCAD to preserve your changes.

FAQ Section

Q1: Can I directly open NWD files in AutoCAD?
No, AutoCAD cannot directly open NWD files for editing. However, you can attach them as external references for coordination purposes.

Q2: What file formats can Navisworks export to?
Navisworks supports exports to several file formats, including DWF, DWFx, FBX, and KML. For formats not supported directly, it is advisable to use the original design software.

Q3: Is there a free version of Navisworks available?
There is no free version of Navisworks Manage, but Autodesk offers limited trials and educational licenses for students and educational institutions. For light viewing, Navisworks Freedom can be used at no cost.
