Reduce the Costs of Quality by Controlling Variation 

3DCS Integrated in CATIA V5


3DCS is a powerful integrated tolerance analysis tool for CATIA V5. It is used to simulate manufacturing processes and assemblies to determine the dimensional impact of variation.

As an integrated solution for Dassault Systemes CATIA V5, 3DCS is opened as a workbench, letting designers and engineers seamlessly transition from design to analysis and back without leaving the CAD environment.

As the first Dassault Systemes Gold Software Partner for CATIA V5, DCS has continually improved on its quality solutions, becoming the most used dimensional analysis tool by major OEM’s in the automotive and aerospace industries, and gaining greater adoption by medical device, electronics, consumer goods, heavy machinery and oil and energy companies across the globe.

V5 Gold Partner V6 Partner  Part of the PLM Marketplace

Using 3DCS to control variation and optimize tolerances has saved customers millions of dollars by reducing rework, scrap, non-conformance issues and warranty claims. As part of the 3D Master strategy, 3DCS has become a valuable competitive advantage for manufacturers.

Benefits of Dimensional Analysis with 3DCS

Optimize Tolerances and Processes

3DCS CAA V5 Based 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 based on key quality characteristics lets the user tighten essential tolerances and measure key areas while relaxing tolerances on less important areas. 

Reduce Cycle Time and Rework Costs

Create digital prototypes by utilizing the Process Capability Database and known manufacturing capabilities. Simulate virtual prototypes to reduce the need for physical prototyping thereby shortening development time, accelerating time to market, and reducing costs.

Identify Key Contributors

Identify the source of variation and determine key characteristics in your design. By maximizing part tolerances while controlling dimensional requirements, manufacturing costs can be reduced with less rework to tools and gages, minimized scrap and reduced warranty defects. 3DCS CAA V5 Based helps your bottom line and significantly improves product quality by validating that parts fit and function together before design release and throughout production.


Push Button Tolerance Analysis Reports

Are wasting time compiling your results into reports?

3DCS lets you create your reports with a single button push.

What used to take days will now take minutes at most. 3DCS automatically compiles images, graphs, charts, tables and data into a linked report available in many different formats.


Tolerance Analysis Report Example



Process Capability Database: Faster Modeling with Manufacturing Data


Faster, more accurate and more consistent modeling using real tolerance process data

Create a database with your historical data or knowledge base and apply it to your models, linking set tolerances on features and points to tolerances set in the database. Link one or multiply tolerances to the same parameters in your database, and update all of your tolerances with the push of a button.

Color Mapping: View Variation and Identify Problem Areas


Color Mapping lets the user quickly identify problem areas, and communicate this information visually. As 3DCS is able to model both assembly variation as well as part variation, Color Mapping can be customized to show only the process variation from assembly, letting engineers isolate different kinds of variation on their model.

Improve Perceived Quality and Visualization


Perceived Quality Spec Stud

Show variation directly on your virtual prototype

(Tolerances exaggerated for demonstration purposes)



Spec Studies use 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 key objectives. 

  • View Build Tolerances on Actual Product Images
  • Set key objectives balancing manufacturing capability and design aesthetics
  • Test Final Visual Quality Early in Design
  • Consider variants without Building Prototypes
