SOLIDWORKS MBD (Model Based Definition) is a paperless manufacturing solution that embeds all product manufacturing information, tolerances, and annotations directly into 3D models. It eliminates the need for 2D drawings, reducing errors and miscommunication across design, manufacturing, and quality control. Integrated with SOLIDWORKS and CAM, it supports tolerance-based machining and secure sharing via eDrawings or 3D PDFs. MBD improves collaboration, speeds time-to-market, and ensures compliance with industry regulations, particularly in sectors like defence and medical. With minimal training required, it enhances efficiency, reduces scrap and rework, and provides a single source of accurate data throughout the product lifecycle.
