<p style="font-size:30px;"> ✅ Overview </p>

</div>


The repository contains the training dataset for our AAAI paper, [NURBGen: High-Fidelity Text-to-CAD Generation through LLM-Driven NURBS Modeling](https://muhammadusama100.github.io/NURBGen/), accepted at AAAI 2026. The paper introduces NURBGen, a novel framework for generating high-fidelity CAD models from textual descriptions using Large Language Models (LLMs) for NURBS modeling. The dataset, PartABC, consists of 300K+ CAD models with varying complexity levels, annotated with detailed textual descriptions and metadata.
