Dimensional Control Systems performs with a simple mission in mind:

To change the way businesses execute Quality Assurance by combining engineering methods with software technology and excellent customer service.

Dimensional Control Systems Inc. (DCS) based in Troy, Michigan, USA is focused on the methodology of Dimensional Engineering. DCS offers best-in-class software solutions and services to manufacturing companies the world over. With over 50 years of Dimensional Engineering background, DCS continuously strives to exceed our customer's expectations for world-class Variation Analysis and Quality Management System (QMS) software and services.  

DCS’s software solutions and engineering services give corporations the toolset for improving and validating their design prior to cutting any tools, reducing scrap, rework, downtime, and non-conformance issues. DCS offers two core software technologies to aid design and production quality, 3DCS Variation Analyst and QDM - Quality Data Management.


In a day when product lifecycles are shrinking, and the demand for getting quality products to market quickly, there is little margin for error. Engineering decisions must be made quickly and efficiently to avoid delays in timing while avoiding quality setbacks while managing your costs.

What if you had a software solution, or a support team of engineers, that provide you with the knowledge to analyze assembly design during the design phases for fit, finish, and function issues relating to variation analysis? Or give you instantaneous access to all of your quality inspection data, anytime, anywhere, and from any source through your web browser, allowing you to make well-informed engineering decisions quickly in an effective manner? 

Software Solutions

3DCS Variation Analyst - Comprehensive Tolerance Analysis:

Variation Analysis (Tolerance Analysis) is the process of analyzing and predicting assembly variation based on component tolerances, piece part geometry, and locating schemes, in other words, a “REAL Virtual Prototype.”

The design community creates details and assemblies based on nominal design. But, without the use of the 3DCS Variation Analysis software, at no time are analyzed designs based on the anticipated variation of the detailed components, or how a particular locating scheme or process will actually increase the variation due to geometry effects. 3DCS does just that, in a virtual environment, saving both time and money.

QDM SPC Platform - Real-Time SPC Quality System:

QDM is a web-based 3-Dimensional graphical quality data management tool for reporting and analyzing measurement data from any device, facility, any location worldwide.

The QDM SPC Platform provides users with the ability to access data from any standard PC from within your secure corporate intranet. QDM-Web allows engineers and managers in quality, product, and manufacturing to easily review real-time (up to the minute) information from the plant floor with a click of the mouse. This gives company-wide manufacturing visibility, allowing you to find and respond to manufacturing problems before they occur.

Dimensional Management

DCS provides two distinct services for dimensional management: 

1. Dimensional Engineering and Modeling

DCS provides services that support dimensional engineering projects. These include modeling using 3DCS software, as well as delivering comprehensive analysis results to engineering teams. By reducing the workload on manufacturer's teams, DCS provides a valuable resource to completing projects ahead of schedule. 

2. GD&T

With experts in GD&T, DCS provides both training and consulting on GD&T. Let DCS help with your product's GD&T and teach your team GD&T best practices and methods. Make manufacturing easier by using ASME Certified GD&T to describe the process and tolerances and communicate that information smoothly between the engineering and manufacturer teams. 


Engineering Staffing 

With a dedicated team to providing qualified candidates to leading manufacturers, DCS prides itself on helping companies add new engineers to their teams quickly through direct hires, or temporarily increase their staff to handle large workloads and projects through contracted engineers. 

DCS exists today because we are passionate about the technology of Dimensional Engineering. As a company our mission at DCS, since the very beginning, has been to establish a work process and system of software tools to help engineers evaluate and ultimately select cost effective designs and processes that will in fact meet their quality needs. Dimensional Engineering is, after all, the process of using dimensional quality goals to drive design process decisions.
