PR-CAD: Progressive Refinement for Unified Controllable and Faithful Text-to-CAD Generation with Large Language Models

PR-CAD introduces a progressive refinement framework that unifies text-to-CAD generation and editing, overcoming limitations of disjoint approaches. It leverages a high-fidelity interaction dataset and a reinforcement learning-enhanced reasoning framework tailored for LLMs to enable controllable and faithful CAD modeling.
