MUSE: Benchmarking Assembly Structure and Interface Geometry in Multi-Component Text-to-CAD Generation
MUSE is a new benchmark for evaluating Text-to-CAD models by testing their ability to create complex, multi-component assemblies rather than just single parts. It pairs practical designs with detailed specifications and checks generated models across three stages: code execution, geometric validity, and design intent alignment using specialized rubrics. Findings show a sharp failure cascade where success in one stage does not guarantee correct assembly structure or manufacturability.
