Enquanto os agentes LLM podem gerar assembleias CAD visualmente plausíveis, esses projetos muitas vezes falham em cumprir suas funções físicas pretendidas. Estudamos o design CAD funcional, um ambiente onde os agentes interpretam pedidos sub-specificados para construir e rever iterativamente mecanismos que satisfazem os requisitos funcionais na simulação física. Verificar esses requisitos é não trivial: mecanismos candidatos diferentes podem realizar a mesma função através de componentes, controles e sequências operacionais 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
