How we ranked these
We ranked the tools by how directly each maker’s own pages tie the product to vehicle engineering, starting with full CAD platforms, then surfacing and cloud CAD, then simulation tools that sit on top of a CAD model. Every fact comes from the maker’s own pages, and only three of the ten publish a price. Simulation tools are included because automotive engineers use them alongside CAD; Siemens, Dassault, PTC and Autodesk each appear twice or fewer. Facts are taken from each maker's own published information; check the official site before you buy.
