How does engineering automation reduce errors in bills of materials and manufacturing drawings?

Manual variant design tends to introduce errors into bills of materials, drawings, and documentation – resulting in incorrectly ordered parts, manufacturing drawings that deviate from the 3D model, and costly rework. Rule-based generation of 3D models, drawings, and bills of materials from a single source of truth automatically produces consistent, production-ready documents. Each variant is validated against the stored rule base, so invalid combinations cannot occur in the first place. In practice, errors in order processing are reduced by at least 30 percent.
