3DCS Variation Analyst is the world's most used tolerance analysis software that is fully integrated into Siemens NX / CATIA V5/ PTC Creo /SOLIDWORKS and CAD Neutral MultiCAD.
It enables designers and engineers to define, test, and modify dimensional product and process requirements in a NX / CATIA V5/ PTC Creo /SOLIDWORKS digital environment before processing. 3DCS Variation Analyst enables manufacturers to quickly evaluate GD&T, assembly tools, and assembly sequences before launching production to fully estimate design, manufacturing, and assembly robustness. Making full use of 3DCS tolerance analysis can reduce the development cost of new products that are quickly brought to market and improve the performance of existing manufactured products.
To put it simply: 3DCS assists designers in clearly predicting the Cpk of important product measurement targets during the design phase, analysing and optimizing product portfolio tolerances.
assembly variation of manufactured products with virtual prototypes
to specific contributors of cumulative variation for optimizing designs
costs and dimensional integrity with proactive variation analysis
3DCS Variation Analyst (Siemens NX / CATIA V5/ PTC Creo /SOLIDWORKS based) it is an integrated solution, users can not only activate 3DCS workbenches from within the modelling solution, they can use many of its inbuilt functionality to support their modelling.
3DCS Variation Analyst Multi-CAD is a standalone CAD neutral software system. It is used for modelling variation that is caused by part tolerances as well as manufacturing and assembly processes. Using Transmagic conversion software, 3DCS Multi-CAD works with native CAD files (.prt, CAD product, etc), STEP, IGES and JT files.
The basic conditions required to perform a complete 3DCS tolerance analysis are :
Advanced Analysis and Optimization (3DCS AAO) is an add-on module to 3DCS that uses and extends current Geofactor-based equations and combines coefficients generated from Geofactor or DOF (design experience) to support non- Linear model.
It able to test datums and locators, view matrices to work with large models and tackle non-linear tolerance stacks. Before using the module, a complete 3DCS model must be built to function properly.
It includes two core functions:
3DCS Mechanical Modeler (3DCS MM) is an add-on module for 3DCS software solutions which can determine the impact of variation on your assembly through its entire range of motion. It able to add kinematic functions, joints and constraints and linkages for mechanical assemblies.
3DCS FEA Compliant Modeler (3DCS FEA CM) is an add-on module for 3DCS software solutions. The 3DCS FEA CM simulates dimensional changes in part deformation, which may be caused by springback, gravity, or manufacturing/assembly production operations (clamping, loosening, welding, tightening, force, etc.).
Determine how the Geometry of your product affects your tolerances
3DCS Geofactor Analyzer determines the sensitivity of tolerances to change. This geometric relationship is displayed as a factor, called a GeoFactor, which is a multiplier to the tolerance based on its influence in the overall assembly.
Determine geometric relationships between parts:
Determine Whether Your Geometry Amplifies or Mitigates Your Tolerances
GeoFactor Analyzer adds to your analysis results by determing the GeoFactor for each tolerance.
As part of the HLM Sensitivity Analysis, GeoFactor improves your overall understanding of the model, giving a value for the sensitivity of each tolerance, whether it is amplified or mitigated by your product geometry.
Determine how your components relate
View the geometric effect of your tolerances. Based off of the geometry, determine how much the geometry amplifies or mitigates your tolerances.
Use the Geofactor Table to see Geometric Factors across your entire model
View all Geofactors in your model in one window. Update your model information and see the effects instantly.
Improve Your Product's Perceived Quality Through Visualization Studies in Leading Tools: Deltagen, CATIA 3DEXPERIENCE, Keyshot, Design Studio and More
Perceived Quality is the quality attributed to a product based on its perceptual experience. This incorporates the experience a customer has with a product and how it makes them feel about that product.
Bringing together the shape, the appearance, the texture, and physical feel of the product as well as the emotional experience of using the product, Perceived Quality directly affects the opinion of the value of the product. This perceived value then drives the business forward.
Visualization Export gives engineers the ability to view simulations of their final product's variation to make decisions about design early in the Product Life Cycle that will ultimately affect their customers' Perceived Quality of the product.
Use visualization tools with Tolerance Analysis to determine the impact of variation on your final product:
Reduce the need for physical prototypes through Visualization
Perceived Quality Studies are a means of communicating quality objectives and attainable quality levels between Design and Engineering teams. This process incorporates iterative studies to determine acceptable aesthetic levels and then confirms manufacturing's ability to meet those objectives.
Perceived Quality Studies can be used to target specific Gap and Flush conditions to see how variation will affect the appearance of the product. Hood to Fender gaps, rear view mirrors, displays on cameras, panels on consumer goods, seats on snow mobiles. Every product benefits from Perceived Quality Studies.
Create Early Studies
Before getting any manufacturing tolerances, use SPEC STUDIES to set Gap and Flush conditions to determine maximum and minimum acceptable levels.
Make Design Decisions Early to Set Parameters
Review the Spec Studies and share with colleagues to determine maximum and minimum acceptable conditions. Review design options and colors to see how these features affect the appearance of the product.
Create a Tolerance Analysis Model to Run Simulations
Complete the Tolerance Analysis Model by adding assembly processes and production tolerances within the given design parameters determined earlier.
Use Simulation to Make Determinations
Monte Carlo Simulation gives statistical probabilities for different variation scenarios. See how these scenario conditions affect your product's appearance.
Just because the design allows the product to be successfully built does not mean it will look good!
