# Save3DAdvanced - ComfyUI Built-in Node Documentation

> Complete documentation for the Save3DAdvanced node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node saves a 3D model to a file in the ComfyUI output directory, with advanced control over the output dimensions and camera/viewport settings. It also passes through the 3D model, model information, camera information, and dimensions for downstream nodes.

## Inputs

| Parameter         | Description                                                                  | Data Type       | Required | Range                               |

| `width`           | Width of the output preview in pixels (default: 1024).                       | INT             | Yes      | 1 to 4096                           |
