3D builds that look right

Ask the 3D studio's Build for a whole thing, a sports car, a house with a garden, a pair of headphones, and it now works the way a good modeller does: it decides the real sizes, the outline and the features that make it recognisable first, then builds every step to that one design.

• A real design up front: overall size and proportions, every part with its size and place, materials and colours. Every step reads all of it, so the parts fit together.
• More detail: curved shapes, cut-outs, rounded edges and repeated parts, up to about 250 parts in a build and about 80 changes a step, never a simplified stand-in.
• Check and fix: when the last step is done, your device takes three pictures of the model and the AI looks at them, finds what's wrong (a part floating, wrong proportions, a missing detail) and fixes it, up to two rounds.
• Calm as before: Check and fix is one more row in the Build card with its price, its fixes undo on their own, and a check that finds nothing to fix is free.
• Pictures you attached go with every step, so the model keeps their shape and colours.
