Introducing CETOL 6σ v12.1: The Latest Software Release from Sigmetrix

CETOL 6σ v12.1 3D tolerance analysis software is now available for download. 

MCKINNEY, Texas – June 5, 2025-- Sigmetrix, announced their latest release of CETOL 6σ tolerance analysis software, version 12.1, 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. This new release of CETOL 6σ builds upon the powerful features already in place and adds many improvements, including:  

• Improved support for patterns per ISO GPS standards, including correct application of the Combined Zone (CZ) modifier and correct referencing of patterns establishing datum in Datum Systems. This extends to annotations created in Creo and NX files by CETOL.
   
• Enhancements to ease the definition of Joint controls, including:
  • Improved automated Joint DOF settings when importing assembly constraints. 
  • Simplified tools to orient joints for fasteners and alignment pins.
  • Ensuring users define specific directions when biasing joints between cylindrical features of size.

• Tools to help users easily understand Assembly State assignments of Parts, Subassemblies, and Joints. 

• Support for Projected Tolerance Zones. 
  
  
• Improved support for Inseparable Assemblies, including: 
  • Import CAD assembly constraints referencing features within Inseparable Assemblies. 
  • Import & link to assembly-level annotations. 
  • Create assembly-level annotations based on tolerances defined in CETOL for Creo and NX. 
    
  
  
• Notification when the model becomes “Not-Closed” after adding new joints that create conflicting definitions.
  
  
• CETOL model “roll-back” bar similar to that found in several CAD systems. 
  
  
• For the NX-Integrated version:
  • Import assembly constraints to create joints. 
  • Annotation Creation for NX allowing users to automatically define Product Manufacturing Information (PMI) from tolerances defined in CETOL.  

As with prior releases, CETOL 6σ v12.1 is available in English, Japanese, and Simplified Chinese. 

 Sigmetrix Director of Customer Success and Product Strategy, Stephen Werst, commented: 

“CETOL 6σ v12.1 is yet another 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 extend CETOL from just an analysis tool to one that can help make better design decisions as early in the process as possible. 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."
