# Exporting

> Export bone models as STL, case data as JSON, and print pre-op reports.

## Exporting

NavNX provides several export options to share surgical plans with colleagues, integrate with other systems, or produce printed documentation.

## Export STL

Export the 3D bone model as an STL file for use in external 3D viewers, 3D printing, or integration with other surgical planning tools.

<Steps>
  <Step title="Open the Bone 3D view">
    Navigate to the Bone view and adjust the threshold to capture the desired anatomy.
  </Step>

  <Step title="Click Export STL">
    Click the **Export STL** button in the toolbar.
  </Step>

  <Step title="Download">
    The STL file is generated and downloaded to your browser's default download folder.
  </Step>
</Steps>

<Note>
  The exported STL reflects the current threshold setting. Adjust the threshold before exporting to control which structures are included in the mesh.
</Note>

## Export Case Data (JSON)

Export the complete case plan as a structured JSON file. This includes:

* Patient demographics (name, MRN, DOB)
* Procedure type and side
* Tunnel parameters (coordinates, angles, diameter, depth)
* Selected implant and size
* Graft configuration
* Measurements
* Case notes

To export: open the case detail page, click **Export**, and select **Case Data (JSON)**.

## Print Pre-Op Report

Generate a formatted pre-operative report for printing or saving as PDF:

1. Open the case detail page or click **Pre-Op Report** in the planner toolbar.
2. The report opens in a new browser tab.
3. Use your browser's print function (**Ctrl+P**) to print or save as PDF.

See [Pre-Op Report](/reports/pre-op-report) for details on report content.

<Warning>
  Exported files may contain protected health information (PHI). Handle exported data in accordance with your organisation's data security policies.
</Warning>

<Tip>
  The JSON export is useful for archiving case plans or transferring plan data to other systems. The format is stable and documented.
