Embodied CAD
Benchmark of parametric B-Rep assembly modeling tasks for LLM agents focused on mechanical and mold-oriented assemblies, where every feature, placement, and assembly relation must pass an exact geometric kernel, scored on solver execution, editability, and intermediate-state validity.
What it does and how it connects
Embodied CAD presents solver-grounded LLM agents for parametric B-Rep assembly modeling. Instead of generating a complete script in one pass, the agent iteratively selects actions from a stratified L0 to L4 CAD skill library, resolves them into typed geometric operations, executes them in a CAD backend, and uses solver feedback to plan, repair and learn.
The framework combines action grammar constraints, deterministic parameter resolution and solver-derived rewards for supervised warm-up and GRPO-style refinement. It is evaluated on multi-step mechanical, industrial-equipment and mold-oriented assembly tasks with solver-aligned metrics: executable rate, skill accuracy, operation-family accuracy, exact policy accuracy and task completion success.
The paper reports that solver-grounded planning executes all strong-planner workflows in the current benchmark, while learned controllers reach high executable rates and expose the remaining gap between valid tool calls and exact long-horizon policy prediction.
