CADENA (anonymous copy for review)

Checkpoints accompanying an anonymous ICLR 2027 submission, provided for double-blind review only. CADENA reconstructs a 3D mesh as a parametric CAD program, growing the operation sequence one step at a time and comparing the target with the currently built geometry before choosing the next operation.

Code: supplementary material of the submission
Benchmark: https://huggingface.co/datasets/cadena45564/cadena-bench

Checkpoints

Subfolder	Stage
`sft`	Supervised, final checkpoint of the second stage (CADENA-SFT)
`rl`	Reinforcement learning against executed geometry (CADENA-RL)

Both are Qwen2-VL-2B policies, 4.4 GB each in bfloat16.
