3DCS Variation Analyst for 3DEXPERIENCE is a fully integrated tolerance analysis solution within Dassault Systèmes' CATIA V6 3DEXPERIENCE platform. It enables manufacturers to simulate product assembly and part tolerance stack-ups using Monte Carlo, Equation-Based, and Sensitivity Analysis methods. Activated as a workbench in CATIA, it provides insights into product quality through metrics like Cp, percent out of specification, and variation range.

Features

• PMI Integration: Uses embedded GD&T (FT&A / PMI) from CAD for instant part tolerancing.
• Perceived Quality Visualization: Creates life-like images of worst-case scenarios to assess visual impact of variation.
• Variation Source Identification: Pinpoints variation sources in parts or assembly processes to optimize design.
• Iterative Design Simulation: Allows simulation of tolerance and process changes to find optimal quality-cost balance.
• Reporting & Measurement Plans: Generates detailed engineering and management reports, and CAD-linked measurement plans.
• Digital Twin Simulation: Includes fixtures, tooling, and multi-stage assemblies in variation analysis.
• GeoFactor Analysis: Evaluates geometric relationships and their impact on dimensional quality.

Benefits

• Reduced Lead Times and Scrap: Validates and optimizes tolerances to minimize rework.
• Improved Product Quality: Enhances both build and perceived quality through visual and analytical studies.
• Cost Efficiency: Identifies non-tolerance-based solutions to quality issues, reducing unnecessary adjustments.
• Enhanced Collaboration: Streamlines communication across teams with comprehensive reports and plans.
• Scalable Across Organization: Supports enterprise-wide tolerance analysis using Model-Based Definition.
