GD&T Advisor

EnginSoft are European distributors of GD&T Advisor based on CETOL6σ technology, developed by Sigmetrix LLC.

Imperfection exists in ALL manufacturing and assembly processes.

GD&T Advisor is your expert guide for the correct application of geometric dimensioning and tolerancing on your design drawings that are necessary to insure the functional requirements of your products. Ensuring compliance with ISO or ASME standards, you will experience greatly improved productivity. For example, using GD&T Advisor will typically expected to reduce time and clicks to apply GD&T by more than 70%.

Intelligent guidance from GD&T Advisor will identify the correct tolerances to apply, which are automatically highlighted, while inappropriate tolerances are blanked out and unselectable. In addition, check the completeness of tolerancing can be checked using an optical colour-coded guide.

Utilise these functions easily from within the PTC Creo or Pro-Engineer CAD environment.

Benefits of GD&T Advisor

  • Increase productivity
  • Reduce costs
  • Standardise annotations correctly
  • Eliminate annotation mistakes
  • Improve design communication
  • Enhance understanding of the GD&T standards
  • Allow designers to better describe the design intent

Address the critical aspects of GD&T application

  • Creation: fast, efficient, intelligent application of functional, syntactically correct GD&T in your 3D model environment
  • Validation: visualised and function-oriented evaluation of GD&T guarantees tolerancing completeness
  • Education: extensive help content, informative tool tips, and an interactive GD&T Quick Reference aid in understanding of GD&T concepts for both the ISO or ASME standard
  • Utilisation: intelligent CAD-native annotations are usable in downstream processes such as drawing production, tolerance analysis, computer aided inspection or manufacturing, and other design activities

EnginSoft are European distributors of leading Precise Constraint Technology software CETOL 6σ, developed by Sigmetrix LLC.

Companies products can fail when it is not possible to assemble the manufactured component parts leaving designers and engineers facing questions such as “Can the product I’ve designed be assembled?” or “Will the product function as intended once assembled?”

Many companies find problems arise from not understanding the potential effects of variation. Parts are designed in a perfect CAD environment, only to come together in unexpected ways as tolerance variations “stack-up” and interact to cause a product failure. To avoid costs and the loss of customer confidence associated with situations like this, businesses have two options: Throw money at the problem by tightening tolerances, which will increase the manufacturing costs, or use the market leading Tolerance Analysis software to intelligently understand and address the issue.

CETOL 6σ is a tolerance analysis and optimisation software tool providing the invaluable insight needed to address the above issues and to confidently release designs for manufacture. You will be able to assess the manufacturability of your designs long before they reach production.

CETOL 6σ enables designers and engineers to address multi-dimensional problems, by using a mathematical description of your CAD geometry. This unique method allows you to receive immediate analytical feedback, utilising the easy-to-use modelling, analysis and reporting components. The user is guided through the tolerance analysis and optimisation process whilst being informed about missing or erroneous data.

Unlike simple 1D stack-up analysis or Monte Carlo Simulation, CETOL 6σ pursues a statistical approach employing advanced precise constraint technology, displayed in an intuitive graphical user interface. This approach accelerates the ability to identify part sensitivities and components that have the most significant contribution to the total variation. Discovering critical-to-quality assembly characteristics has never been easier.

Benefits of CETOL 6σ

  • Achieve maximum productivity
  • Improve product quality
  • Accelerate product maturity
  • Optimise design & manufacturing goals
  • Identify critical parts in assemblies
  • Reduce scrappage and warranty claims
  • Reduce manufacturing cost
  • Reduce modelling time
  • Communicate results efficiently
  • Quickly auto-report results

Key Features

  • Rich graphical interface and modelling wizards
  • Precise sensitivity analysis combined with true sensitivity animation
  • Analytical, statistical, and worst case tolerance analyses
  • Rapid “what-if” analysis without re-simulation
  • Interactive, on CAD model analysis visualization
