      User Guide – Checksize V1.0

      📦 Key Features

      1. ✅ Single Item Verification

      Checksize operators can now perform verification and validation of item dimensions from a dedicated tab in the VTO Quality Control module.

      Accepted search fields:

      • GlassesID

      • EAN

      • SKU

      The system automatically checks:

      • Lens width

      • Bridge width

      ⚙️ Verification Methods (Algorithms)

      Two algorithms are used in Checksize, but the selection is automatic and based on the availability of qualification:

      🔹 Classic Checksize

      • Used by default when no qualification is available for the item.

      • Compares the manufacturer’s declared dimensions with those measured directly from the 3D model.

      • Does not account for the bevel.

      🔸 Frame Boxing

      • Automatically used when qualification is present.

      • A more precise algorithm, it takes into account:

        • The bevel

        • The qualified areas (either manually entered or extracted during preprocessing)

      ➡️ In summary: if the item is qualified, Frame Boxing is always applied.

      2. 📂 Batch Item Verification

      Checksize allows batch validation by uploading a CSV file containing multiple items.

      How it works:

      • The CSV file must include item identifiers.

      • Each item is processed using the appropriate algorithm based on qualification presence.

      • Errors or inconsistencies are flagged in the interface.

      3. 🔁 Correction and Revalidation of Invalid Items

      To streamline the correction workflow:

      • Operators can download the corresponding data4 file for any item marked as invalid.

      • After making corrections, the item can be reuploaded.

      • The system will then automatically revalidate it.
