DCS Quality Solution

Closing the loop on quality by combining design and manufacturing

A closed-loop variation analysis process enables engineers to correlate the theoretical tolerance analysis results produced during simulation to the actual as-built results determined at other stages of the quality process.

DCS supports a closed loop by aligning the simulation power of 3DCS with the manufacturing visibility of QDM. Together, the Quality Intelligence system gives you the ability to support your entire PLM process. 

DCS Supports Dimensional Quality through PLM

Just a Few of Our Customers

DCS is proud to work with leading manufacturers from across the globe


































Advantages during the pre-production phase are root cause analysis - only recently we've actually really started using the software to root cause the problems. We've found that looking at the contributor lists, for example, really help us get to the root cause of the problems and propose solutions. 

Laurence Allmark,

Senior New Product Quality Engineer, McLaren Automotive

Successful tolerance analysis product execution played a major role in our achievement of high quality across our product vehicle line. The Chevrolet Volt, Chevrolet Silverado, Chevrolet Malibu and Cadillac CTS were all named Car/Truck of the Year winners.

General Motors

The 3DCS technology brought our commitment to product quality and safety by design to an even higher level. The tool not only can quantify our technical decisions but truly helps our IPD teams to numerically and visually discuss spatial dimensional variations and its management early in the design phase.

Daniel C. da Silva,

Embraer Tolerance Analysis Team Leader, Embraer

In a typical section of an A320 Family Aircraft, roughly 90 stringer couplings are installed. Around 2/3 can be covered with the parametric model (this equals 60...couplings.

In the A319, A320 there are 4 section joints, while the A321 has 6. One parametrical model can then cover 180 assembly situations

Axel Siewert,


By being able to do very comprehensive modeling, the other advantages we’ve seen is we’ve discovered sensitivities in areas we wouldn’t have expected you know well outside our region of interest that had influence, it’s also served as a quality check for our drafting process as well as allowing us to incorporate feedback from the manufacturing floor.  

Avery M.

Design Engineer

As CAD technology continues to advance to include greater levels of analysis, our open API strategy allows us to support the incorporation of tools like 3DCS software to keep up with the growing demands of customers. The partnership between Siemens and DCS will allow an integrated environment, giving NX users access to advanced analysis as part of the CAD environment.
