# 🧩 FreeCAD Sketch Python Dataset

This dataset contains approximately **1,000** Python files and their corresponding images defining **parametric FreeCAD sketches**. Each python file represents a geometric sketch scripted using the FreeCAD Python API.

The dataset is intended for **training and fine-tuning large language models (LLMs) and vision large language models (vLLMs)** and other AI systems to understand and generate **CAD-based parametric geometry code**, particularly for **text-to-CAD** and **text-to-3D** applications.

---

## 📁 Dataset Overview

* **Number of files:** ~2,000 (1,000 python scripts & 1,000 images) 
* **Format:** Python (`.py`) & Portable Network Graphics (`.png`)
* **Image Size** 1920 x 1080 pixels
* **Language:** English (`en`)
* **License:** CC BY 4.0
* **Domain:** CAD, Parametric Geometry, FreeCAD
* **Primary Use:** AI / ML training and research

---

## 🧱 Naming Scheme

Each file follows a consistent naming pattern:

```
PartName_SketchName.py
PartName_SketchName.png
```

This structure helps learning-based models associate:

* Part-level semantics
* Sketch identities
* Parametric geometric definitions

---

## ⚙️ Source Information

- **Part files sourced from:**  
  [FreeCAD Library](https://github.com/FreeCAD/FreeCAD-library) - It is a large collection of CAD geometries freely available in FreeCAD Addons.

- **Sketch parsing and conversion handled by:**  
  [freecad_sketch_parser](https://github.com/yas1nsyed/freecad_sketch_paser) - A github project by me to convert the CAD geometries into python scripts and images. This parser converts FreeCAD `.FCStd` part files into corresponding Python code that defines their sketches using the FreeCAD API.
---

## 🧠 Intended Use

This dataset is designed for:

* Training or fine-tuning **code generation models** on CAD scripting tasks
* Research on **LLM-assisted CAD design**
* Developing **text-to-sketch** and **text-to-3D** pipelines
* Learning parametric geometry constraints and sketch construction patterns

### ⚠️ Limitations

* The dataset focuses on **sketch-level geometry**, not full solid modeling pipelines unfortunately.
* Generated scripts assume a valid FreeCAD runtime environment.

## 🧾 Example

Below is a simplified example of a sketch definition from the dataset:

```python
import FreeCAD, Part, Sketcher

doc = FreeCAD.newDocument()
sketch = doc.addObject('Sketcher::SketchObject', 'BaseSketch')

sketch.addGeometry(
    Part.LineSegment(
        FreeCAD.Vector(0, 0, 0),
        FreeCAD.Vector(10, 0, 0)
    )
)

sketch.addConstraint(
    Sketcher.Constraint('Coincident', 0, 1, -1, 1)
)

doc.recompute()
```
