3DCS Variation Analyst is the world’s most widely used tolerance analysis software, fully integrated into major CAD platforms. Developed by Dimensional Control Systems (DCS), it enables engineers to simulate and analyze both part and process variation using 3D models. This allows manufacturers to create digital twins of their assemblies, optimize designs, and validate manufacturing processes before physical production begins. The software is used across industries such as aerospace, automotive, medical devices, electronics, and industrial machinery. It supports platforms including CATIA V5-V6, 3DEXPERIENCE, SOLIDWORKS, PTC CREO, Siemens NX, and a standalone Multi-CAD version.

Features

• CAD Integration: Seamless operation within CATIA, SOLIDWORKS, CREO, NX, and 3DEXPERIENCE.
• 3D Tolerance Stack-Up Simulation: Analyze dimensional variation and its impact on assembly performance.
• Digital Twin Creation: Simulate real-world assembly processes and variation sources.
• Part & Process Variation Modeling: Account for manufacturing and assembly variability.
• GD&T Validation: Test and optimize Geometric Dimensioning and Tolerancing.
• Gap & Flush Analysis: Determine optimal conditions for fit and finish.
• Process Optimization: Simulate manufacturing sequences to identify best practices.
• Measurement Data Integration: Use plant data to resolve production issues in CAD.
• Multi-Industry Support: Trusted by companies like Airbus, BMW, GM, LG, Nissan, Samsung, and Volkswagen.
