SVG / CVPR 2027 CAD+FEM research data

Large files for the code at https://github.com/ayushdebnath012/SVG (branch cvpr2027-research-package): CADFEM-Bench releases (v1.1-v1.7, final), challenge and dataset packages, web-collected CAD and FEM sources, solver outputs, agent-run replays and model adapters. Paths mirror the GitHub repository, so its scripts find the files when this repo is placed at the same root.

Licences are mixed and follow each source (see the catalog.json / README in each source folder); some sources are non-commercial or carry no stated licence. Check the source terms before reuse.
