Product type  : Engineering Solutions

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.

GeoFactor Analysis

Determine geometric relationships between parts:

  • Determine the multiplicative effect of variation on your tolerance changes
  • Determine which tolerances contribute the most variation
  • Identify critical tolerances
  • Determine how changing specific tolerances will affect the overall variation

Tolerance Relationships are Not Always 1 to 1

Determine Whether Your Geometry Amplifies or Mitigates Your Tolerances

GeoFactor Analyzer adds to your analysis results by determing the GeoFactor for each tolerance.

Key Benefits:

  • How does changing a tolerance affect overall variation – If you tighten or loosen a tolerance, how much will actually affect your assembly?
  • How does the geometry of your product affect the influence of your specific tolerances – How does the assembly process and build affect the influence of your tolerances?

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.

VISUALIZATION EXPORT

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.

Improve Customer Perceptions

Use visualization tools with Tolerance Analysis to determine the impact of variation on your final product:

  • Experience the Design Impact
  • Predict the probability of variation scenarios
  • Create virtual prototypes to see design changes
  • Validate both design and engineering

Make Early Design Decisions Based on Virtual Prototypes

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.

Steps in a Perceived Quality driven PLM Cycle:

  • Design Spec Studies and Visualization
  • Review Specifications (ex. Gap and Flush) and Determine Objectives
  • Create Tolerance Analysis Models and run Monte Carlo Simulations
  • Share and Approve/Reject Results

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.

Design Spec Studies and Visualization

Create Early Studies

Before getting any manufacturing tolerances, use SPEC STUDIES to set Gap and Flush conditions to determine maximum and minimum acceptable levels.

Process:

  • Design Visualization
  • Add Measurements
  • Define SPEC STUDIES
  • Review SPEC STUDIES with Visualization (Right example: CATIA 3DEXPERIENCE)

LS-DYNA IN METAL FORMING

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 3DCS Model - Prepare Tolerance Analysis

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.

  • Modify Tolerances to Engineering Specifications
  • Run Monte Carlo Simulations

Monte Carlo Simulation

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!

Benefits:

  • See the probability of different conditions based on the design
  • Incorporate influence from assembly processes and engineering specifications
  • Make decisions about acceptable specifications
  • Share SIMULATION STUDIES with colleagues to quickly collaborate
