3DCS Mechanical Variation Analyst CAA V5

Model Mechanical and Kinematic Assemblies Quickly and Easily


 Predict – the assembly variation

React – to specific contributors

                Control – costs and dimensional integrity


Take your mechanical assemblies to a new level with 3DCS Mechanical Variation Analyst CAA V5 Based.

3DCS Integrated in CATIA V5


As a Dassault Systemes Premier Gold Partner, 3DCS Mechanical Variation Analyst is fully integrated into the CATIA V5 environment, allowing the testing and analysis of products before production, saving time and money by preventing costly problems later on.



3DCS Mechanical Variation Analyst CAA V5 Based is a specialty tool geared for mechanical manufacturing. 3DCS MVA allows users to model mechanical and kinematic assemblies with full range of motion. This, in addition to a kinematic solver, allowing tolerance analysis of over-constrained assemblies, makes 3DCS MVA an excellent fit for performing variation analysis on engines, switches, gears and other mechanical components.

Optimize Product Designs and Processes

3DCS Mechanical Variation Analyst CAA V5 Based (3DCS MVA) allows CATIA users the ability to evaluate design and assembly concepts up front, where problems can be identified early in the product development lifecycle. Optimizing for dimensional integrity improves the robustness of your design and process by maximizing part tolerances while maintaining the dimensional requirements of your final assembly.

Reduce Cycle Time and Rework Costs

Shorten development time, accelerate time to market, and reduce costs by utilizing the capabilities of 3DCS MVA for digital prototyping. By maximizing part tolerances while controlling dimensional requirements, manufacturing costs can be reduced with less rework to tools and gauges, minimized scrap and reduced warranty defects. 3DCS MVA reduces your bottom line and significantly improves product quality by validating that parts fit and function together before design release and throughout production.

Spec Study for Perceived Quality Spec Study applies advanced photo realistic rendering along with part and assembly variation, allowing easy identification of tolerance requirements for styling, management, design studio, and engineering to cost effectively establish dimensional specifications that will allow your designs to meet market quality perspectives. 

  • View Build Specifications
  • Test Variants
  • See Tolerances on Photo-Realistic Images
  • Test Final Product Quality in Early in Design

Save views, visual specifications, tolerance schemes and backgrounds in toggleable studies. 

Having the ability to assess dimensional build specifications, or customers “Perceived Quality” of fit and finish characteristics, in the digital concept design phase with advanced photo-realistic visualization offers manufacturing companies a way to test product quality before the costly investment in tooling begins. 

Making a virtual assessment of the fit and finish assembly requirements offers design studios, advanced product quality planning, and even design engineers a way of defining, analyzing and modifying dimensional product.
