Material

Material captures the specified material for a part or feature, including the raw designation, normalized classification, and any supplementary notes. It may also include density, standards references, and supplier hints if the drawing provides them. 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 metadata can feed directly into quoting tools or change management workflows. The object also records confidence scores and contextual references so you can reconcile similar material names across different languages or legacy nomenclature, and it highlights when alternate materials are suggested in notes.
