3DCS Design Variation Modeler (DVM) is an entry-level, equation-based 3D tolerance analysis software developed by Dimensional Control Systems (DCS). Fully integrated into major CAD platforms, DVM enables engineers to simulate and analyze dimensional variation in assemblies using GD&T and PMI data. It is designed for components assembled in a single station with planar and axial locating features, making it ideal for early-stage design validation and quality assurance. DVM is part of the DCS Scalable Solution, allowing organizations to expand tolerance analysis across teams and departments using Model-Based Definition (MBD) to drive quality downstream.

Features

• CAD Integration: Works within CATIA, NX, Creo, SOLIDWORKS, and other major platforms.
• PMI Extraction: Automatically extracts GD&T, joints, and constraints from CAD models.
• Equation-Based Simulation: Provides instant results from tolerance stack-up analysis.
• True 3D Stack Analysis: Accounts for 3D influences for more accurate variation modeling.
• GeoFactor Analysis: Evaluates geometric relationships between tolerances and overall assembly quality.
• Root Cause Identification: Pinpoints sources of variation from tolerances or assembly processes.
• Fast Model Updates: Allows design changes without rebuilding the model.
• Iterative Design Testing: Supports rapid testing of design variants and tolerance changes.

Benefits

• Accelerated Design Validation: Quickly simulate and analyze tolerance impacts during design.
• Reduced Scrap and Rework: Identify and resolve variation issues before production.
• Improved Collaboration: Enables broader access to variation analysis across teams.
• Cost Efficiency: Minimizes manufacturing costs by optimizing tolerances early.
• Supports MBD and MBSE: Promotes model-based engineering practices for quality assurance.
• Scalable Deployment: Easily integrates into enterprise workflows as part of the DCS Scalable Solution.
