# Engineering Talk - DCS's Blog on Quality and Engineering

## Modeling Methods shows how to apply different moves in 3DCS to account for non-standard conditions.

Next week is the last webinar in the 3DCS Version 7.5 Series - Modeling Methods. This webinar will focus on 3DCS Moves, more importantly, advanced Moves and applications that can help new and advanced users with modeling.

# 3 Reasons Why You Should be Using PMI, FTA and Digital GD&T

## There are a lot of benefits to using digital GD&T in your CAD platform; here are 3 of the big ones.

Automotive and aerospace manufacturers are leading the way with the application of digital GD&T technology. Applying digital GD&T to frame rails, aircraft skins, fuselages and body in white assemblies, these manufacturers are able accurately simulate part and process variation and then take steps to control and reduce its impact on the final build.

This is the general application of GD&T in a digital environment, but what are the reasons to promote using digital GD&T in the first place?

# 4 Ways Excel is Failing Your Tolerance Analysis

## Excel is a useful tool for a lot of applications, and can be used in a pinch for stack analysis, but it misses a lot of important features.

Excel can be used a for a lot of equation based applications. Many companies rely on it for their tolerance analysis; doing 1D stacks and stack-up analysis using Excel macros and Visual Basic code. For basic cases, this works great and can be a fast and effective way to get answers quickly, but as soon as products, models and requirements become more complex, Excel falls flat.

Integrated CAD tools give more accurate analysis results by incorporating additional influences

This means that your Excel answers might be misleading you, and can cause some embarrassing, and expensive, problems later on.

In what ways is Excel failing?

## Here are 4 ways Excel is failing your tolerance analysis:

### 1. No 3D Influence

It is rare that all the parts in your product line up into a perfect linear line. Most often, there are parts arranged around your stack-up, and these part's tolerances will influence your linear stack. This 3 dimensional influence can cause more variation than you'd expect, and a 1D stack-up in Excel is not going to account for this.

Even with a linear stack-up, you can have angularity that will cause additional variation, or variation and issues unaccounted for in your Excel stack. These 3 dimensional issues are related to the geometry of the parts, and require a CAD-based approach to properly simulate and validate.

Not all scenarios can be calculated with an Excel 1D stack-up

# DCS Rolls Out the New Version of 3DCS Variation Analyst Software

### 3DCS Version 7.5 comes packed with new features, and a lot of improvements too

UPDATE: The link to download the WHAT's NEW pdf has been fixed! We apologize for the trouble.

The new version of 3DCS includes improvements and new features that both improve tolerance analysis, but also improve the speed at which the results are delivered.

## Back to Basics: How to Quickly Add Points, Moves and Tolerances to Your 3DCS CAD Model

### This Back to Basics article covers a number of ways to quickly add Moves, Tolerances and Points to a 3DCS model

Anyone who has worked with CAD knows that the most time consuming task is preparing the model for analysis. This process is the 'necessary evil' in order to get the results you need to make decisions and validate your GD&T. This is, of course, needed in order to model assembly joints and constraints that mimic the real world. There are, of course, ways of speeding up the process.
