          Create GD&T and GPS Annotations Quickly and Easily with GD&T Advisor

          Sigmetrix’s GD&T software helps designers apply crucial product manufacturing information up to four times faster than with standard CAD authoring tools.
          PREMIER GD&T SOFTWARE FEATURES

          Apply Standards-Based GD&T and GPS Annotations in Your CAD Environment

          Incorrect or unclear application of geometric tolerances creates massive inefficiencies, internal debate, and costly scrap. Save time and money with the premier ASME GD&T and ISO GPS annotation software, GD&T Advisor.

          • Enjoy an interactive experience with the software that provides expert guidance on ASME GD&T and ISO GPS application consistent with the governing standards.
          • Work directly within PTC Creo, applying annotations 4X faster than with the standard authoring tools.
          • Apply annotations that are readable by downstream software systems, including tolerance analysis and computer-aided inspection systems.
          • Get recommendations for the most common GD&T or GPS control for any selected feature in a part model.
          • Avoid mistakes: GD&T Advisor will guide the user to create annotations consistent with the governing standards.
          • See color-coded demarcation within the model to assess what features have been completely controlled, partially controlled, or not yet controlled at all.
          • Receive helpful messages and resources to learn and improve without ever leaving the program.
          • Click to open a context-sensitive help screen when GD&T Advisor identifies an issue with an annotation, allowing you to quickly understand why the message is being displayed.

          Get Guidance and Alerts on Your GD&T and GPS Annotations Within CAD

          The many benefits of GD&T Advisor go beyond just time savings—you can also improve your geometric tolerancing knowledge and proactively eliminate annotation errors with native tools and embedded resources. 

          • Use precise mathematics to get recommendations on the most appropriate control for the feature selected while seeing messages on why others are not recommended or appropriate.
          • Adhere to national and international standards, including ASME and ISO.
          • Improve manufacturing accuracy with a uniform application of functional dimensioning and tolerancing that can be understood across the enterprise.
          • Avoid mistakes—unlike standard CAD authoring tools, GD&T Advisor will not allow you to accidentally create invalid annotations that could cause slowdowns in later design phases.
          • Gain contextual understanding of errors and sharpen your skills as you go with software that offers explanations instead of just flagging errors without insight into why they’re occurring.
          • Save thousands of dollars a year on the scrap that results from engineering change orders as well as unexpected warranty expenses.
