contact-usCreo Parametric 4.0 is your go-to release for model-based definition. There are a ton of new features for realizing a MBD model. Refer to the following free downloads:

Creo GD&T Advisor is an extension to Creo Parametric 4.0 that provides expert guidance on the application of GD&T and validation that it has been done correctly. When the model is complete, you can be confident that it complies with the relevant standard and is fully constrained. Creo GD&T Advisor also improves your productivity when applying GD&T, reducing the number of mouse clicks and time required to apply and validate GD&T. It also simplifies the understanding of the complex GD&T standards by providing readily available guidance during every step of the application process. Rulesets included are ASME Y14.5-2009, ISO 1101-2012, and their associated standards.

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 way.

Key benefits of GD&T Advisor

  • Increases productivity
  • Reduces costs
  • Provides consistency
  • Eliminate mistakes due to human error
  • Improve design communications, reducing the chance of misinterpreted or ambiguous information

  • Feature-centric workflow guides the user
  • Fast creation of annotations


  • Complies with ASME and ISO standards
  • Fully constrains the model geometry


  • Extensive help content
  • Advisor messages provide feedback on status of the GD&T applied to the model

Creo GD&T Advisor reduces the error between as-designed assemblies and as-produced products through intuitive modeling technologies and advanced visualization techniques. The functional Feature Centric GD&T provides for:
