# The CAD Hub

> A directory of CAD, CAM, CAE, PLM, PDM, simulation, rendering, and 3D printing software, with engineering software guides and free browser tools.

Use the public read-only JSON API to search and filter products, then follow each result's url for citation or markdown_url for full text. No account or JavaScript is needed. Only published articles are exposed.
Listings describe software rather than endorsing it. Prices and versions may change; verify current details with the vendor. A missing price is unknown, not necessarily free. updated_at describes the listing's last edit, not when the vendor's details were verified.
