3 Strengths of Model Based Definition

According to O’Fallon Casting, OFC Customers have varying degrees of MBD implementation.  Some provide a solid model with a fully dimensioned drawings others with partially dimensioned and sometimes with drawings that contain no dimensions whatsoever.  O’Fallon Casting has found that limited dimension drawings, especially for larger sizes of castings, are an effective way for an...

For Better Product Quality, Explore MBD [Interview]

If you’re an engineer or designer, you’ve probably already heard about model-based definition (MBD), the practice of adding non-geometric engineering information to a 3D model. (Traditionally, that data is added to a 2D drawing.) Intuitively, it makes sense to keep everything in one place. But are the benefits worth the effort of changing the way... Continue Reading →

Should Your Organization Implement MBD? [Interview]

Some say that model-based definition (MBD), the practice of adding engineering information to a 3D model, can help improve productivity and quality, while also reducing costs. On the surface, that’s something every organization, engineering manager, and design engineer wants, of course. But, is MBD still “faster, better and cheaper” if your team’s productivity suffers as... Continue Reading →

MBD: Define Once, Reuse Many Times [Interview]

In recent weeks, Madhavi Ramesh@Punditas, has been talking to industry experts about model-based definition (MBD) in product design and development. How do these experts define MBD? Who needs it? How can companies get started using it? In this week’s post, she talks to Raphael Nascimento, a product manager who was key in developing model-based definition... Continue Reading →

Combination States and Model-Based Definition (MBD)

MBD is based on Y14.41-2003 Digital Product Definition Data Practices that establishes standards and requirements for tolerances, dimensional data, and other digital design annotations on 3D solid models.  Combination States are important in the MBD context as they facilitate the presentation of model and the related annotations. Combination States in Creo Parametric In Creo Parametric,... Continue Reading →

Model Based Definition (MBD) and YOU

The momentum is building for Model-Based Definition (MBD). Get ready now. MBD is a process which results in a 3D CAD model that is the complete product definition. All the information about your product lives in a fully-detailed, documented 3D model accessible to everyone from engineering to package design. Sounds good, but what does it... Continue Reading →

GD&T Advisor for MBD

In a drawing centric world, the non-geometric attributes (GD&T) that are required to manufacture the products, such as dimensions, tolerances, datums, etc., are on the 2D Drawing. However, in an MBD world this non-geometric information, that is critical for downstream Manufacturing and Inspection processes, must be contained within the model in a clear and un-ambiguous...
