What Sigmetrix does
Sigmetrix is a privately held US software company founded in the mid-1990s and headquartered in McKinney, Texas, that develops tolerance analysis and geometric dimensioning and tolerancing (GD&T) solutions for precision manufacturers. Its product portfolio centers on five CAD-integrated tools — CETOL 6σ (3D model-based statistical tolerance analysis), EZtol (1D/2D stack-up analysis), GD&T Advisor (in-CAD GD&T authoring and verification against ISO GPS and ASME Y14.5), VariSight (enterprise-level variation data management), and EZTA (in-CAD tolerance calculation) — each delivered as extensions to PTC Creo, CATIA, SOLIDWORKS, or Siemens NX. With 30+ years in the field and participation in ISO GPS and ASME Y14.5 standards development, the company positions itself as a specialist bridging nominal design and real-world manufacturing variation.
The company sells primarily to enterprise manufacturers in aerospace & defense, automotive, medical devices, electronics, electric generation and distribution, HVAC and appliances, and pumps and compressors — verticals where regulatory compliance, safety, and dimensional precision are binding constraints. Named customers include FN Manufacturing, Hilliard Corporation, an unnamed automotive parts manufacturer, and an unnamed medical device manufacturer; use cases include tolerance optimization on mature product lines, statistical analysis of complex assemblies, and resolution of field-failure issues such as caster misalignment in operating-room equipment. The revenue model combines CAD-embedded software licensing with a substantial professional services layer: enterprise training delivered in-person, virtually, and self-paced; expert-led consulting by senior application engineers; and implementation services. Distribution is direct enterprise field sales, with "Request a Demo" as the primary conversion mechanism, supplemented by an on-demand training storefront and active content marketing.
Sigmetrix operates globally, with stated delivery across North America, Europe (Germany), and Asia (China), and is led by President Ed Walsh (appointed June 2026, previously COO with 18+ years at the company), CEO James Stoddard, and Founder Tim Bogard. The company is privately held, with no disclosed institutional investors, funding rounds, or M&A activity in the available data.

Sigmetrix product offering
Product offeringCore offering
Sigmetrix develops and sells CAD-integrated tolerance analysis and GD&T (Geometric Dimensioning & Tolerancing) software that helps manufacturers identify, simulate, and manage mechanical variation across assemblies. The portfolio includes CETOL 6σ for 3D tolerance analysis, EZtol for 1D/2D stack-up analysis, GD&T Advisor for GD&T/ISO GPS scheme creation within CAD, VariSight for enterprise variation data management, and EZTA for CAD-based tolerance calculation, complemented by training, consulting, and implementation services.
Product overview
Sigmetrix provides a unified portfolio of mechanical variation management solutions comprising five core software products and three service offerings. The software suite includes: Cetol 6σ (comprehensive 3D tolerance analysis), EZtol (1D/2D stack-up analysis), GD&T Advisor (GD&T authoring within CAD), VariSight (enterprise variation data management), and EZTA (CAD-based tolerance calculation). These products integrate directly with major CAD platforms (PTC Creo, CATIA, SOLIDWORKS, Siemens NX) to enable seamless tolerance analysis and GD&T workflows. The portfolio is complemented by Training Services (GD&T and tolerance analysis training), Consulting Services (expert-led project support), and Implementation Services (deployment and onboarding). Sigmetrix has over 30+ years of experience helping enterprises produce better products through mechanical variation management.

Sigmetrix competitors and assessment
Company assessmentDirect peers
- InnovMetric Software: Maker of PolyWorks, the leading 3D metrology and dimensional inspection software platform. Overlaps with Sigmetrix in dimensional analysis workflows, though oriented around measurement hardware integration rather than pure tolerance stack-up.
- Dimensional Control Systems: DCS develops 3DCS Variation Analyst, the most direct functional competitor to Sigmetrix's CETOL 6σ for 3D tolerance analysis and stack-up. Targets the same aerospace, automotive, and heavy equipment customers with similar CAD-integrated tolerance workflows.
- Variation Systems: Variation Systems offers VisVSA, a tolerance analysis and variation simulation tool directly competing with CETOL 6σ and EZtol. Focused on complex assembly variation for automotive, aerospace, and industrial machinery.
Broad incumbents
- Siemens Digital Industries Software: Maker of NX CAD and the Tecnomatix portfolio. Sigmetrix is an integration partner within Siemens NX, but Siemens also has its own tolerance and variation analysis capabilities, making it both partner and potential competitive threat.
- Hexagon Manufacturing Intelligence: Broad metrology and manufacturing intelligence vendor with PC-DMIS and related dimensional inspection software. Competes with Sigmetrix in the quality/metrology workflow though with a much broader portfolio spanning hardware and software.
- PTC: Maker of Creo CAD and the broader PLM/Arena/ThingWorx portfolio. As Sigmetrix's Creo integration partner, PTC could expand native tolerance analysis functionality within Creo, eroding Sigmetrix's value proposition.
- Dassault Systèmes: Developer of CATIA and the 3DEXPERIENCE platform, which includes native GD&T and tolerance functionality. Sigmetrix integrates into CATIA, but Dassault could deepen native capability to compete directly.
- Mitutoyo: Global leader in precision measurement instruments and related metrology software. While primarily hardware-focused, Mitutoyo competes with Sigmetrix at the dimensional quality and tolerance specification layer.
- Renishaw: Provider of measurement and manufacturing process control systems, including probing and metrology software. Overlaps with Sigmetrix in industrial dimensional quality and variation management use cases.
Emerging players
- Materialise: Materialise provides 3D printing software and services including tolerance and quality tooling (3-matic, Magics). Adjacent to Sigmetrix in design-to-manufacturing workflows, with overlap in aerospace and medical device verticals.
