What's in the box

One viewer, three jobs: identify, illustrate, and link to your stock.

Three.js + glTF viewer
Tested against the NIST FTC 07 robot arm, LifeTrac v5 tractor, and industrial assemblies up to ~1,300 meshes. Pans and explodes smoothly on a phone.
BOM-to-3D auto-matching
Upload a BOM CSV alongside your STEP. We score each match and flag the low-confidence rows for review.
Plugs into your storefront
Web component plus a postMessage add-to-cart event — works on Shopify, WooCommerce, Odoo and custom carts. The viewer never owns the cart.

Plugs into your storefront.
The viewer posts add-to-cart events to your page; your existing checkout takes it from there. Works anywhere you can drop a web component.
