Geometric Dimensioning & Tolerancing (GD&T)

Simplify GD&T standards with expert guidance during every step of the application process

What Is geometric dimensioning and tolerancing (GD&T)?

GD&T is the process of annotating designs and drawings for downstream processes, such as tolerance analysis, inspection and other production activities, using a symbolic language to define the allowable deviation of feature geometry.

GD&T can be a painstaking process, but it doesn’t need to be. 

Creo GD&T Advisor provides expert guidance, saving you time and mistakes.  Your completed model can be validated for compliance with the relevant ASME and ISO standards. 

Creo GD&T Advisor improves your productivity, reducing the time required by up to 75%. You’ll apply GD&T correctly the first time, saving money and reducing tedium.

Why Creo GD&T Advisor?

View an example of how Creo GD&T Advisor helps to address problems often encountered during the dimensioning and tolerancing process.

The GD&T Advisor Plus allows you to reuse the accurate parts of your legacy GD&T annotations while highlighting errors that they may have and providing recommendations on how best to resolve the problems uncovered.

GD&T and Model-Based Definition (MBD)

GD&T and Tolerance Analysis are part of a broader Model-Based Definition journey. MBD is an approach to creating 3D models that effectively contain all product data needed to define a product. With MBD, the model becomes the single source of truth that drives all engineering activities – from concept development through design, simulation, manufacturing, and service.

With Creo’s Model-Based Design Suite, you get an integrated extension that helps ease compliance with MBD standards leading to more efficient product development cycles, reduced manufacturing costs, and less rework.
