SOLIDWORKS PMI - Save Time by Using SOLIDWORKS PMI and GD&T for DVA Dimensional Variation Analysis

SOLIDWORKS PMI and GD&T Reduce Confusion and Improve Efficiency in Dimensional Variation Analysis - DVA

Utilizing your PMI and GD&T written in your CAD platform can save you from re-creating all of your tolerances, and reduce the chance for errors in dimensional variation analyses

Integrated tolerance analysis makes it easy to take advantage of CAD PMI and GD&T. Many CAD platforms have tools to create and validate GD&T, and can be used to improve the DVA process.

Digital Twin -- Which Digital Twin Did You Mean?

This article originally published on CENIT's Blog at

Everywhere we read and hear about the splendid future of the digital twin. But descriptions of what this technological concept actually means can vary a great deal. Anyone who takes a closer look at the topic quickly realizes that there are reasons for these diverging views, and understanding them makes it easier to arrive at the right investment decisions.


How to Update Your Dimensional Variation Model with Design or Engineering Changes in SOLIDWORKS

How to Incorporate Engineering and CAD Model Changes into Your Dimensional Variation Analysis

CAD model and part updates are common during most product life-cycles and design phases, but can be difficult to incorporate into existing studies. 3DCS streamlines this process to make it easy to update existing and current analyses.

Dimensional engineers are often setting up their models and studies while the design team continues to revise the  CAD model that the analyses are based upon. As the designers continue to revise the model with engineering changes, design changes, and process changes, these updated CAD parts are passed to the engineers who need to update their studies.

In many cases, this can cause issues, as 1D stacks and many Excel based studies need to be started from the beginning with new parts, changes in hole sizes or location, or the addition of new features. 3DCS, however, has some quick tools to bypass these issues, making the use of new and updated parts easy.

SOLIDWORKS Tolerance Analysis - Why Manufacturing Simulation Matters

Manufacturing Simulation Takes Tolerance Analysis to the Next Level

Tolerance Analysis often refers to just part tolerance stacks, leaving out a large piece of the big picture

Common tolerance analysis determines the combined variation from a series of interconnected parts in a one-dimensional or two-dimensional stack, such as below. Done commonly in Excel, these analyses are excellent for quick answers and simple assemblies. They do fall short quickly when you need to consider larger number of components, parts in three-dimensional configurations, and of course, starting over every time there is a design change or different output needed. The example below also depicts some complications with even a basic one dimensional stack.

What is the QIF Standard for Model Based Definition MBD?

What is the QIF Standard?  

The QIF Standard is best thought of as a container. It holds a group of data together, providing unique identifiers for each feature and characteristic. This makes moving the data from team to team within an organization and into the supply chain much easier, as all the relevant data is present in one location, and the characteristics can be properly identified and communicated between people and machines by using the QPId (QIF Persistent Identifier) numbers to remove ambiguity. This allows a clean workflow of information downstream, while connecting all components of the digital thread. The enterprise gains trace-ability and transparency into their own workflow through versioning with QPId's.

QIF Persistent Identifier (QPId) 

  • Universally Unique Identifier (UUID) [adopted by Microsoft as GUID]
  • ISO/IEC 9834-8
  • example... 550e8400-e29b-41d4-a716-446655440000
