prs-eth/point2cad — reverse-engineered prompt

Build me a simple way to run Point2CAD on example files and on my own 3D point cloud files.

I want to give it a point cloud where each point has x, y, z, and a surface id, then have it reconstruct the CAD style surfaces, edges, and corners. Please make it easy to run with Docker like the README suggests, save everything into an output folder, and include clear instructions for how to use the sample data in the assets folder and how to point it at my own file.

I don’t need a fancy app. A clean command line workflow is fine. It should tell me where the unclipped surfaces, clipped surfaces, and topology results are saved, and fail with helpful messages if the input format is wrong or Docker is not available. If you need details about the current setup or dependencies, look up the docs online if needed.
