CAD2Program is an advanced vision-language system presented at AAAI 2025 that automatically converts 2D CAD drawings into 3D parametric models. This software leverages state-of-the-art artificial intelligence to interpret complex engineering diagrams and reconstruct them as editable, dimensionally accurate 3D geometries. It is designed for engineers, architects, and researchers who need to streamline the transition from legacy 2D documentation to modern 3D workflows. The tool serves as a powerful research prototype demonstrating the capabilities of multimodal learning in computer-aided design. The project includes source code for its official research website, which is built using a template originally developed for the Nerfies project.
