Material

Material captures the specified material for a part or feature, including the raw OCR text, the normalized designation, and the standard the designation follows when the drawing provides one. It also carries a three-level material category classification that places the material in a hierarchy such as metal, steel, or a specific alloy family. Structuring material information allows you to integrate with inventory systems, validate compatibility with manufacturing processes, or trigger compliance checks. Because material choices influence cost and lead time, the model’s data can feed directly into quoting tools or change management workflows, and the raw OCR text lets you reconcile similar material names across different languages or legacy nomenclature.
