This repository contains a fine-tuned Qwen3-VL model adapted for CadQuery-style CAD/code understanding and generation, trained on the ThomasTheMaker/cadquery dataset.

Model details

Developed by: IFMedTechdemo
Base model: unsloth/Qwen3-VL-8B-Instruct-unsloth-bnb-4bit
License: Apache-2.0
Dataset: ThomasTheMaker/cadquery (~2000 examples)
Training: 30 epochs
Training stack: Unsloth + Hugging Face TRL

Intended use

This model is designed to help with CAD / parametric modeling workflows that resemble the CadQuery dataset distribution, including:

Generating CadQuery-style Python code from natural-language CAD instructions.
Explaining or modifying existing CadQuery snippets (e.g., “add 4 holes”, “increase wall thickness”, “fillet edges”, “change dimensions”).
Basic reasoning about geometric intent described in text (dimensions, features, operations).

How to use (example)

Typical usage is as an instruction-following model where you provide:

A natural-language task description, and optionally
A partial CadQuery snippet to modify

Example prompt:

“Create a parametric bracket with two mounting holes (M4), 3mm thickness, and a 20mm standoff. Output CadQuery code.”

Notes on training

Fine-tuned for 30 epochs on ~2000 items from ThomasTheMaker/cadquery.
Unsloth was used to speed up training and improve memory efficiency; TRL was used for the fine-tuning loop.

Deployment

This repo is tagged for text-generation-inference and transformers. You can run it with standard Transformers inference or deploy via TGI depending on your environment and quantization support.

Limitations

The model can produce code that is not directly executable (syntax/import issues, missing variables, or invalid CadQuery API usage).
Dimensions/constraints may be inconsistent; validate outputs before using them in production CAD pipelines.
Complex assemblies, tight tolerance constraints, and manufacturing-ready outputs may require human review and iterative refinement.
