Model Based Definition

All information intelligently connected
September 3, 2025

Model Based Definition (MBD) is a holistic, digital approach to defining and describing products or components on the basis of a 3D model. In contrast to traditional 2D drawings, the 3D model contains all the necessary information to ensure a consistent and machine-readable product description. This creates a single point of truth. MBD reduces the time and cost of model description and improves collaboration and communication during the product life cycle. This helps to avoid errors, which increases the quality of the end product.

Why is DRWE a first-class choice for your company?

With Siemens NX MBD and automation tools, DRWE enables more efficient use of the PMI application. Automated and updating rules, such as the complete dimensioning of holes, make the application more precise and time-saving. The DRWE provides both basic knowledge and individual MBD rules that can be created in the Logic Editor task environment. These rules are based on reusable methods that combine object-specific inputs and logic to achieve desired results efficiently.
