            • EZtol – 1D tolerance stack-up analysis.
            • GD&T Advisor – standards-based application of GD&T and GPS annotations.
            • VariSight – enterprise-level mechanical variation management.
            • EZTA – In-CAD (PTC Creo) 1D tolerance stack-up creation and analysis with PMI linking and automated loop definition.


            Pricing & Licensing

            How is Sigmetrix software licensed?

            Licensing is offered as named-user or network (floating) licenses, depending on customer needs. Subscription options are available.

            Can I purchase software directly online?

            No, all Sigmetrix software is purchased through a direct sales engagement to ensure the right solution and licensing fit.

             

            Supported CAD Versions & Releases

            Which CAD systems are supported by CETOL 6σ?

            CETOL 6σ integrates with:
            • PTC® Creo®
            • Siemens NX
            • CATIA®
            • SOLIDWORKS®

            What version of CETOL is available for Creo?

            The latest release of CETOL is compatible with current versions of Creo. Specific version compatibility varies by release.

             

            Which CAD systems are supported by EZtol?

            Trials, Proof of Concept, and Demos

            Does Sigmetrix offer a free trial?

            Sigmetrix does not currently offer downloadable trial versions of CETOL or EZtol. Instead, prospects can request a sales-led demo tailored to their CAD system and use cases.

             

            What about a proof of concept (POC)?

            POCs are not offered as self-directed trials. Instead, Sigmetrix provides guided demos and training packages to help teams validate the software’s fit.

             

            Training & Certification

            Does Sigmetrix provide training?

            Yes. Sigmetrix offers instructor-led training, virtual classes, and online courses covering CETOL, EZtol, GD&T Advisor, tolerance analysis, and GD&T fundamentals.

             

            Are certifications available?

            Sigmetrix provides certificates of completion for its training courses. Industry-recognized certifications may be offered for advanced programs. 

             

            How do I learn tolerance stack-up?

            You can learn tolerance stack-up through:
            • EZtol software demonstrations and training courses
            • CETOL 6σ training for more advanced 3D analysis
            • GD&T and tolerance analysis training classes offered by Sigmetrix

            Product Comparisons

            What’s the difference between CETOL and EZtol?

            • CETOL 6σ: Designed for full 3D tolerance analysis. Best for complex assemblies, multi-dimensional variation, and engineering teams who need comprehensive insight.
            • EZtol: Designed for quick 1D stack-up analysis. Best for engineers who need a faster, simpler way to validate assembly variation without building detailed 3D models.

            When should I choose CETOL instead of EZtol?

            • Choose CETOL 6σ if your product requires robust 3D analysis, high reliability, or is highly complex.
            • Choose EZtol if you need to quickly perform tolerance stack-ups during design without the depth of 3D analysis.

            Training vs. Software Fit

            Which solution is best for learning GD&T and tolerance analysis fundamentals?

            • GD&T Advisor is the best choice for learning and applying standards-based annotations.
            • EZtol is a good entry point for understanding stack-ups.
            • CETOL 6σ is recommended once you’re ready to apply tolerance analysis at the 3D model level.

            Next Steps

            How do I get started with Sigmetrix software?

            The best way is to schedule a guided demo with a Sigmetrix expert, who can show you the software within your CAD environment. From there, your team can engage with training resources and receive guidance on licensing.
