How we ranked these
Product design here means physical and industrial product design (concept renders, CAD, generative design and simulation), not UX or app design. We ranked tools on the AI features each vendor documents on its own pages for designing physical products, then on published price. Where a vendor page lists no price we say Not published, and we only claim AI features the vendor states. Facts are taken from each maker's own published information; check the official site before you buy.
