What is MBD and GD&T? Is it PMI?
If you are looking at Model-Based Definition (MBD), you must also consider Geometric Dimensioning and Tolerancing (GD&T) and how your organization will incorporate it. What is GD&T? It is a set of symbology representing the mathematical definition that identifies the allowable variations of the actual part. Quality engineers and inspectors use this language to compare the engineering requirements against the actual fabricated parts’ measurements and determine if they are in or out of specification. I have not taught an […]

Why Aren’t There Basic Dimensions in MBD?
Jennifer Herron shares her thoughts on one of the questions we get asked a lot in the Model-Based Definition (MBD) transition: Why aren’t there basic dimensions? We get asked this all the time by folks who haven’t been through our training. Typically, they think basic dimensions have to be measured, which is inaccurate. There are theoretically perfect dimensions that are used […]
