Model-based definition is an approach to creating 3D models so that they effectively contain all the data needed to define a product. With MBD, the model becomes the source of all product and manufacturing information (PMI), which drives all engineering activities.
Model-based definition (MBD), sometimes called digital product definition (DPD), is the practice of using 3D models (such as solid models, 3D PMI and associated metadata) within 3D CAD software to define (provide specifications for) individual components and product assemblies.
SOLIDWORKS MBD enables you and your team to quickly define and organize design and manufacturing information to automate manufacturing, reduce ambiguity, and simplify production operations.
Model-based definition (MBD) makes 3D models your central source for all product manufacturing information (PMI) throughout the lifecycle. Instead of using 2D engineering drawings, MBD embeds all product data—such as dimensions, tolerances, and material specifications—directly into the 3D model.
MBD replaces traditional 2D drawings with 3D models that contain all the critical information needed for design, manufacturing, and inspection processes. By embracing MBD, engineers can communicate complex design concepts more effectively, eliminating confusion and reducing errors.
Model-Based Definition (MBD) replaces traditional 2D engineering drawings with a fully annotated 3D digital model. MBD enhances communication between design, manufacturing, and inspection by embedding critical data directly into the CAD model.
Model-Based Definition (MBD) is an approach where the 3D CAD model contains key product and manufacturing information (PMI)—such as dimensions, tolerances, materials, and annotations—alongside the geometry.
Model-Based Definition (MBD) is a methodology in engineering design that uses 3D digital models as the authoritative source of product definition data, integrating all the information necessary to define a product directly into the CAD model.
