SOLIDWORKS MBD (Model-Based Definition) is an integrated paperless manufacturing solution that embeds product manufacturing information (PMI), tolerances, and annotations directly into 3D models. It eliminates the need for 2D drawings, reducing errors and speeding time-to-market. MBD supports tolerance-based machining in SOLIDWORKS CAM and secure sharing via eDrawings or 3D PDFs, ensuring a single source of truth across design, manufacturing, and quality control. This approach minimizes miscommunication, scrap, and rework while meeting compliance requirements in sectors like defense, medical, and aerospace. Easy to adopt with minimal training, MBD enhances collaboration and efficiency throughout the product lifecycle.
