# Preview3DAdvanced - ComfyUI Built-in Node Documentation

> Complete documentation for the Preview3DAdvanced node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node provides an advanced 3D model preview with camera and model information output. It saves the 3D model to a temporary file and displays it in the UI, while also passing through the model data, camera information, and viewport dimensions for further processing downstream.

## Inputs

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