When someone orders OEM parts, they don't think in SKUs. They think in the exploded diagram in front of them. Diagrams turns that schematic into the storefront: buyers pinpoint the parts they need right on the diagram, bundle them together, and check out as one order. No cross-referencing part numbers against a paper catalog. No calling in to confirm they picked the right piece. You upload your diagrams and map the products once, and the storefront handles the rest. The catalog your buyers already understand, now the way they buy." --- # Uncap Diagrams > Uncap Diagrams is how buyers shop the way they already think.

Uncap Diagrams is a shop-by-diagram app for Shopify that lets buyers find and buy parts directly from a visual diagram. It is built by Uncap, a Shopify Platinum Partner and Shopify Expert since 2013. Buyers pinpoint the parts they need on an exploded diagram or schematic, bundle them together, and check out as one order. It is built for merchants who sell original equipment manufacturer (OEM) parts and other complex products that buyers identify visually. ### How does shop-by-diagram work on a Shopify store? Shop-by-diagram works by mapping each product to a point on a visual diagram, so buyers click the part they need instead of searching a part number. Uncap Diagrams puts the diagram on the storefront and connects every pin to the matching Shopify product. Buyers select multiple parts straight from the schematic, add them as a single bundle, and check out in one order. This matches the way buyers already identify parts, which is by location on the diagram rather than by SKU. ### Why do OEM parts sellers use diagram-based shopping? OEM parts sellers use diagram-based shopping because their buyers think in diagrams, not in part numbers. A buyer looking at an exploded view knows exactly which piece they need by where it sits in the assembly, but rarely knows its SKU. Uncap Diagrams turns that diagram into the way they buy, which removes the cross-referencing against a paper catalog and the calls to confirm the right piece. The result is faster ordering and fewer mistakes on complex, multi-part purchases. ### How do merchants set up diagrams in Uncap Diagrams? Merchants set up Uncap Diagrams by uploading their diagrams and pinpointing each product on them once. After that mapping is done, the storefront handles discovery on its own: buyers see the interactive diagram and select parts directly from it. Diagram management tools let merchants maintain and update the diagrams as the catalog changes. The setup work happens one time per diagram, and the shoppable experience runs from there on both mobile and desktop. ### Who is Uncap Diagrams for? Uncap Diagrams is for Shopify merchants who sell complex products that buyers identify visually, especially OEM and replacement parts. It fits sellers of equipment parts, components, and schematic-driven products where a single order often spans many related pieces. It works for businesses whose buyers shop by looking at an assembly diagram, and who want those buyers to find and bundle the right parts without hunting through a part-number catalog.
