          Sigmetrix To Be Sponsors at COExperience 2024

          2 Minute Read


          Attendees will be able to explore how Sigmetrix can help them maximize the return on their MBD/MBE investment while delivering  a faster time to market.


          MCKINNEY, Texas – May 6, 2024-- Sigmetrix, global experts in mechanical variation management announced that they will be attending COExperience 2024 being held from May 13-16 at the Sheraton Dallas in Dallas, TX. 


          COExperience helps users and their company leverage their Dassault Systèmes solutions through education, training, networking opportunities, product influence and best practices available exclusively to COE members. The Sigmetrix team is proud to be a “Silver Partner” for this show and will be at Booth C7 in the Technifair. Sigmetrix will demonstrate how their tools can help identify the problems or risks related to how variation is controlled in a design.


          There is a lot of discussion in industry about Model-Based Definition, Industry 4.0 and Digital Thread. Many companies are starting down the path toward a Model-Based Enterprise, but that path can be challenging. There are many facets to becoming truly Model-Based, but as the name implies, the key is the models themselves and their connections to various parameters.  It is important that all requirements be tied directly to this comprehensive set of models to ensure traceability and usability. One set of requirements that is critical to the quality of any product is its dimensional requirements that are used to control mechanical variation. Sigmetrix, with its knowledge of managing mechanical variation, can help maximize the return on your MBD / MBE investment in the following ways:

          • Ensure the integrity of your MBD to maximize usability.
          • Guide the creation of optimal dimensioning schemes, including GD&T.
          • Promote consistent knowledge between contributors and consumers.
          • Assess and improve the maturity of your organization’s Mechanical Variation Management.

          In addition to impacting cost, variation can affect cycle time. In today’s market, many companies either want to reduce development costs/time or want to gain a competitive edge by beating their competitors to the market. Sigmetrix understands that ignoring mechanical variation during the initial design can create multiple iterative design loops. Sigmetrix is helping to avoid these issues by:

          • Gaining insights that prototypes do not typically provide.
          • Analyzing product concepts that were previously too difficult to model.
          • Providing consistency of data and understanding throughout the process.

          Sigmetrix has been Dassault Systèmes Gold Partner since 2002 with CETOL 6σ for CATIA V5-6. CETOL 6σ couples the power and functionality of Dassault Systèmes’ CATIA parametric design capabilities with precise calculations and advanced mathematical technologies.

          Attendees will want to make sure to catch Stephen Werst, Director of Customer Success, and Product Strategy, present “Managing Mechanical Variation As Part of the Digital Thread” on Thursday May 16th at 1:30PM CT.

          “Many companies today still consider tolerance analysis as the final analysis activity performed on the design before it is released to manufacturing. Unfortunately, some don’t allot enough time in the design process to perform the necessary studies, or, even worse, knowingly opt not to perform them and release the models and/or drawings with the expectation that problems occurring during the first production runs will be fixed as they occur. Such approaches usually lead to excessive, and often hidden, costs that erode profit margins over the life of the products,” states Stephen Werst, Director of Customer Success, and Product Strategy.


          In addition to demonstrating CETOL 6σ at their booth Sigmetrix will be showing off their entire portfolio of comprehensive, easy-to-use solutions including:

          • EZtol, a 1D analysis tool designed to make it easier to create, manage and report upon multiple 1D tolerance analyses in an assembly.
          • Training, provided through more than a dozen instructor-led and computer-based courses covering basic to advanced GD&T/GPS, MBE, and MBD
          • Consulting and implementation, services with years of experience in tolerance analysis and GD&T definition offer a variety of consulting services to augment your team, speed your project along and run analyses for your assemblies.
