## Model Summary
**CADFS-2B** is a fine-tuned version of [Qwen2-VL-2B-Instruct](https://huggingface.co/Qwen/Qwen2-VL-2B-Instruct) for parametric CAD generation. Given a **text description** or **multi-view images** of a 3D object, the model outputs a [FeatureScript](https://cad.onshape.com/FsDoc/) code that reconstructs the object as a fully parametric CAD model importable into [Onshape](https://www.onshape.com).

---

## Usage
For inference code and FeatureScript to STEP file conversion please visit the [CADFS GitHub repository](https://github.com/VladPyatov/CADFS).
