GeoFusion-CAD: Structure-Aware Diffusion with Geometric State Space for Parametric 3D Design
arXiv CS.CV

ArXi:2603.21978v1 Announce Type: new Parametric Computer-Aided Design (CAD) is fundamental to modern 3D modeling, yet existing methods struggle to generate long command sequences, especially under complex geometric and topological dependencies. Transformer-based architectures dominate CAD sequence generation due to their strong dependency modeling, but their quadratic attention cost and limited context windowing hinder scalability to long programs. We propose GeoFusion-CAD, an end-to-end diffusion framework for scalable and structure-aware generation.
