          Create More Precise Designs and Cut Waste With ASME GD&T and ISO GPS

          Sigmetrix’s GD&T solutions help design and manufacturing teams understand permissible variation earlier in the design process.
          FUNCTIONAL DIMENSIONING AND TOLERANCING

          Save Time and Money by Preventing Mechanical Variation Issues

          Geometric dimensioning and tolerancing (GD&T) and Geometrical Product Specifications (GPS) are languages that use a special set of symbols to define the size, location, orientation, and form of a part feature. These languages symbolize the relationship between a feature and a measurement reference and allow engineers to demonstrate any tolerances or modifiers on a specific part.  

          Too much variation at a critical feature location can cause problems during assembly, resulting in scrap, rework, field failures, loss of productivity, and warranty and liability costs. Incorporating functional dimensioning and tolerancing annotations during the design process can help circumvent these costly issues.  

          Discover the Benefits of GD&T and GPS

          Implementing functional dimensioning and tolerancing through state-of-the-art software offers benefits across the enterprise. 

          Meet International Standards
          Utilize GD&T or ISO GPS to meet national (ASME) and international (ISO) standards for manufacturing.
          No More Guessing Design Intent
          Use a consistent, clear method for communicating design intent to downstream personnel.
          Improve Operational Efficiency
          A universal language reduces the need for teams to explain complex requirements to one another, so they can work faster.
          Work Seamlessly with CAD
          By integrating directly in a CAD environment like PTC ® Creo ®, engineers can perform GD&T and GPS analysis efficiently.
          Simplify Tolerance Analysis
          A more precise and standardized method for specifying and communicating tolerances results in better control and predictability of mechanical variation.
          Eliminate Costly Rework
          Manufacturing and inspection personnel can read the exact specifications of the design team, making assembly more predictable and accurate.
          Do Easy Tolerance Stack-Ups
          Perform tolerance stack-ups and statistical tolerance analyses from within the CAD model.
          Create the Lowest-Cost Functional Parts
          Produce components with a more optimized process, limited waste, and efficient teams.

          Give Your Team an In-Depth Understanding of GD&T and GPS

          Sigmetrix breaks the mold by teaching GD&T and GPS with courses centered around the how and why to use the language. We eschew outdated training methodology that relies on rote memorization in favor of collaborative, experiential learning that offers lessons on how to apply GD&T and GPS, what happens when it’s applied incorrectly, how to check annotations for correctness, and more. Our team of world-class tolerance analysis experts are directly involved in ASME working groups to help develop and maintain the standards we help manufacturers adhere to. We also attend varied industry events every year to learn and teach about using functional dimensioning standards across industries.
