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.

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.

Rulesets included are ASME Y14.5-2009, ISO 1101-2012, and their associated standards.
