Please click on the images below to learn more about Sigmund Tolerance and Variation Analysis software for SOLIDWORKS.





SigmundWorks, a powerful 3D tolerance analysis software for SOLIDWORKS developed by Varatech, enables designers, engineers to evaluate, optimize and validate assembly build quality, relative to piece part tolerance and assembly process variation. Fully integrated within SOLIDWORKS and the Only Certified Gold Partner solution, this value-added software can be used early in the development phase before design solidification. SigmundWorks prevents costly design issues, manufacturing build fires, scrap, rework, and tweaking delays at ramp-up.

SOLIDWORKS Integration:

 Unrivalled Ease of use & Quick to learn - Designed for the non-specialist.

 Single Window Integration - no need for geometry transfer.

 Associative to SOLIDWORKS Geometry & Tolerances

Works with GD&T, Linear Tolerances (Reference, Annotations, Sketch, Extruded), DimXpert.

 Intelligent Nominal and Tolerance based Interference Visualization at Worst case, Min, Max conditions.

 Works seemlessly with Part, Assembly and Drawing modes of SOLIDWORKS.



Five analysis types: Worst Case, RSS, MRSS, PCRSS, and Monte Carlo Simulations.

Objective Driven Roll-Down & Traditional Roll Up approaches for performing tolerance stackup analysis.

Wide range of statistical distributions, extensive data mining and report generation capabilities.

Optimize designs with unique tolerance optimization and cost minimization techniques.

Identify Cost Saving Opportunities. Automatic Statistical, Sensitivity, Tolerance Impact, What-if, and SPC reports.

Design Validation to ensure all criteria are met and automatic write back of optimized data to SOLIDWORKS.

SigmundABA for SOLIDWORKS is an assembly build analysis software that allows engineers to evaluate the 3-D effects of component tolerances on the quality of designed products. Sigmund provides engineers with an easy-to-use interface to evaluate the capability of their designs, ensuring that assemblies go together 100% of the time, while meeting all the quality & performance requirements.


SigmundABA can be used to resolve complex assembly build problems, evaluate design improvements, identify key SPC contributors, determine optimal tolerances for parts and assemblies created in SOLIDWORKS. Using Sigmund from design concept through production will improve quality, reduce costs, and cut development life cycle times.

Development of Sigmund variation model follows an intuitive, step-by-step methodology that includes Component Geometry Creation, GD&T or Tolerance Emulation & Tolerance/Design Optimization



SigmundABA Kinematics is the World's only assembly build analysis software that allows engineers to evaluate the effects of variation on a mechanism throughout its range of motion/operation.


Consider piece part/assembly variation and kinematic motion analysis in the same environment.

Allows defining relative motion between multiple parts/components by using different kinematic joints, such as - primitive, revolved, cylindrical, universal, planar, ball, and bearing joints.

Allows assigning different driver motion in a mechanism.

Allows considering variation analysis in both open and closed loop mechanisms with zero to multiple degrees of freedom.

Can animate kinematic motion and trace the range of motion for a specific feature at both nominal and deviated conditions.

Can evaluate thousands of outputs throughout the range of motion in mechanisms.


    Sigmund ABA Kinematics can be used to resolve complex assembly problems for kinematic mechanisms, evaluate design improvements, identify important design characteristics, and determine optimal tolerances for parts and assemblies.

    Avoid creating multiple models by considering variation and kinematic motion at the same time.

     Allows accurate assembly of closed-loop kinematics mechanisms in a real-world variation environment.

    Can identify non-build conditions because of actual and accurate constraints applied at specific joints.

    Can evaluate the effects of variation throughout the range of motion in mechanisms.

    Can compare them with the nominal range of motion relative to what you might see in an ADAMS model.

    Can generate automated reports showing multiple indices of information throughout the range of motion.
