Yas1n/FreeCAD_Sketches

🧩 FreeCAD Sketch Python Dataset

This dataset contains 3,000 Python files that define parametric FreeCAD sketches. Each file represents a geometric sketch scripted in Python and is ideal for training large language models (LLMs) or fine-tuning code models to understand and generate CAD-based geometric design code.

📁 Dataset Overview

• —Number of files: ~3,000
• —Format: Python (.py)
• —Language: English (en)
• —License: Apache 2.0
• —Purpose: Training LLMs for text-to-CAD and text-to-3D applications.

🧱 Naming Scheme

Each file follows the pattern: PartName_SketchName.py

This consistent structure helps models learn associations between part names, sketch features, and parametric geometry definitions.

⚙️ Source Information

• —Part files sourced from: FreeCAD Library

• —Sketch parsing and conversion handled by: freecad_sketch_parser

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 and parametric geometry generation.
• —Developing text-to-3D and text-to-sketch models.

🧾 Example

Below is an example snippet of a sketch definition:

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()
