About Sigmetrix


Sigmetrix designs, develops, markets and globally supports tolerance analysis solutions used to unite the “ideal” world of product design with the “real” world of manufacturing and assembly. With over 25 years of research and development, Sigmetrix is focused on eliminating the error between predictive tolerance models and measured physical results in the factory. Through intuitive modeling technologies, engineers construct very precise tolerance variation models directly from the CAD geometry. Sigmetrix’ advanced analytical solutions and specialized services allow companies in virtually all industries to gain profound insight into the behavior of their products. This insight allows customers to objectively balance competing requirements and achieve exceptional return on their investment.

Although its benefits are widely recognized, advanced tolerance analysis traditionally has been difficult for engineering organizations to exploit because it is time consuming to get a valid model that can produce reliable results. CETOL 6σ overcomes these barriers by leading users to quickly create a validated tolerance model through optimized GUI’s.

Sigmetrix is a group company of Cybernet Systems Co., Ltd.  In 1999, PTC® selected CETOL 6σ as its preferred tolerance analysis solution. In 2002, Sigmetrix became a Dassault Systèmes Gold Partner providing a fully-integrated version for CATIA® named CETOL 6σ CAA V5-based.   In 2008, Sigmetrix finalized the integration and partnership with SOLIDWORKS® and was named to their Certified Gold Partner Product Program in 2015.

Sigmetrix introduced a complete solution that has provided the ability to integrate with three of the leading Mechanical CAD systems, CETOL 6σ for PTC® Creo®, CETOL 6σ for CAA V5 and CETOL 6σ for SOLIDWORKS.

PTC and Sigmetrix partnered in 2007 to serve the low-end market with a new product named Tolerance Analysis Extension powered by CETOL™ Technology (TAE). TAE is a highly-automated, simplified tolerance analysis solution for getting on-demand answers on less complicated problems completely within the PTC Creo system. TAE is sold directly by PTC sales channels and re-sold by Sigmetrix.

Sigmetrix is continuing to develop the CETOL 6σ and TAE product lines as the premier assembly analysis and tolerance optimization solutions in the world today. Through the company’s unique research relationship with the top universities and strategic software development and distribution relationships with PTC and Dassault Systèmes, Sigmetrix is uniquely positioned to accelerate worldwide implementation of CETOL 6σ and TAE into companies using PTC Creo, SOLIDWORKS and CATIA.
