Reduce Assembly Variation with Robust Tolerance Analysis Software

Sigmetrix is a global leader in tolerance analysis software, standards-based GD&T authoring software, training in all aspects of dimensional management, including GD&T, and dimensional management consulting services. Our software solutions are used by systems, mechanical, and manufacturing engineers worldwide because of their powerful capabilities presented in a logical, easy-to-use interface.

The result of more than 25 years of research and development, Sigmetrix’ software solutions unite the “ideal” world of product design with the “real” world of manufacturing and assembly in which mechanical variation has a significant impact on product cost. Through the intuitive modeling technologies and advanced visualization techniques within CETOL 6σ, our customers gain insight into the source of error in their products that would not otherwise be seen until production starts or field failures are observed! This insight allows companies to manufacture higher quality, lower cost, and more robust products.

Tolerance Analysis and GD&T Authoring Technologies

CETOL 6σ is a 3D tolerance analysis software tool that works directly with your PTC® Creo®, CATIA®, SOLIDWORKS®, and Siemens NX™ files. EZtol is a 1D tolerance analysis (stackup) software tool available as a standalone supporting source files from most of the major CAD systems used for product design. It is also embedded within Autodesk Inventor and soon to be embedded within PTC Creo.

EZtol is a 1-Dimensional tolerance stack up analysis program designed to assist in understanding the impact of the accumulation of part-level dimensional variation and part-to-part assembly variation sources and the impact that they have on assembly-level requirements.

GD&T Advisor is an interactive solution that provides expert guidance on the correct application of GD&T. It is fully embedded within both PTC’s Creo and Autodesk Inventor CAD systems.
