CETOL 6σ v12.0 tolerance analysis software is now directly integrated with NX.  

MICKINNEY, Texas  January 20, 2023 – Sigmetrix, experts in mechanical variation management, announced their latest release of CETOL 6σ tolerance analysis software, version 12.0, is now available for immediate download. Tolerance analysis benefits businesses in many ways. It helps improve profitability by balancing quality with manufacturing cost. Companies can also realize faster time to market by reducing the need for additional design and prototype cycles. Finally, it allows companies to gain confidence in their product and process decisions before making costly investments. 

 CETOL 6σ enables product development teams to understand the often-complex impact of dimensional and assembly variation easily and fully on their designs. This knowledge enables them to make the proper adjustments before problems appear in manufacturing or, even worse, in their customers’ hands. Users of all expertise levels will appreciate the multiple levels of assistance available within the software. This new release of CETOL 6σ builds upon the powerful features already in place and adds many improvements, including: 

  • A New Version of the Software Directly Integrated with Siemens NX- CETOL 6σ users will now have the option of using CETOL 6σ as an add-in application within the NX environment, supporting the additional capabilities of saving the CETOL 6σ data embedded within the NX files as well as automatically pushing changes to linked tolerance values back to the PMI in NX. The standalone version of CETOL 6σ for NX is still available as well to facilitate migration to the new solution, as data from the standalone version may be opened in the new, integrated version.  
  • Select Auxiliary Features for Other Conditions Auxiliary Features, functionality first added in 3, may now be referenced to modify the location of measurement endpoints, to modify the location of a joint, or to modify the location of a feature origin.
  • Reset Joint DOFs CETOL 6σ has applied an algorithm to automatically set degree-of-freedom controls for joints being imported or manually added based on the order in which they are added. Adjusting the setting when the order wasn’t correct, though, is now much faster with this new context menu option.
  • Add Geometric Tolerance Context Menu Option This provides the user the convenience of adding a geometric tolerance directly from the context menu for the feature in addition to the standard tool in the ribbon.
  • Upload to VariSight – Uploading data to VariSight, a new, enterprise-level product for the managing CETOL 6σ data files schedule to be released later this year, is now supported directly within the application.

As with prior releases, CETOL 6σ v12.0 is available in English, Japanese, and Simplified Chinese. 

Sigmetrix Director of Customer Success and Product Strategy, Stephen Werst, commented, “CETOL 6σ v12. is a significant step forward for Sigmetrix as we strive to achieve feature parity across all supported CAD platforms, continue to make the software easier to use, and prepare for the upcoming release of our newest product, Varisight. This release, along with improvements in our entire product portfolio, continues our unrelenting efforts to help companies build better products through mechanical variation management via a robust combination of software, training, and consulting services."
