Mientras que los agentes de LLM pueden generar conjuntos CAD visualmente plausibles, estos diseños a menudo no cumplen con sus funciones físicas deseadas. Estudiamos el diseño funcional de CAD, un entorno en el que los agentes interpretan solicitudes subespecificadas para construir y revisar iterativamente mecanismos que satisfagan los requisitos funcionales en la simulación física. Verificar estos requisitos es no trivial: diferentes mecanismos candidatos pueden realizar la misma función a través de componentes, controles y secuencias operativas completamente diferentes.

While LLM agents can generate visually plausible CAD assemblies, these designs often fail to fulfill their intended physical functions. We study functional CAD design, a setting where agents interpret underspecified requests to construct and iteratively revise mechanisms that satisfy functional requirements in physical simulation. Verifying these requirements is nontrivial: different candidate mechanisms may realize the same function through entirely different components, controls, and operating sequences. To bridge this gap, we propose FunCAD-Harness, a framework that translates abstract requ
