Chat CAD — design a car in 3D, then test it like an engineer

Describe or sketch a car → get a real 3D model you can edit part-by-part (hood, doors, roof, bumpers, glass) → an AI photoreal concept render → and run neural engineering surrogates on it: aerodynamic drag, surface pressure (Cp), wall shear stress (WSS), and a 3D crash deformation.

Hardware: runs on CPU basic (free) for the 3D car, part editing, drag/Cp/WSS and the 3D crash. Set hardware to a GPU (T4) to enable the SDXL photoreal render (it needs a GPU). Paste your own Anthropic or Google AI key in the UI for the natural-language agent; nothing is stored server-side.

Surrogates trained on DrivAerNet / DrivAerNet++ (Elrefaie, Dai & Ahmed, CC BY-NC 4.0) — non-commercial research/demo. Built by Samarjith Biswas, PhD — samarjithbiswas.com.
