- Share links and client approvalSend a link anyone can turn in 3D, embed it in a shop, and have a client approve a version by name.
- Design Facts: weight, stones and ring sizeWhat Design Facts measures from your file, how, and how far to trust the numbers.
- Plans and limitsWhat Free and each paid plan include. Renders are unlimited on every plan: they run on your own graphics card.
