How to Simulate Material Thickness in 3DCS Tolerance Analysis

 How to Better Treat Thickness Tolerances in Sheet-Like Materials

We encounter many situations where there is a form tolerance on a primary surface and then the other side of the part has a thickness allowance. Often implicitly it is assumed to have the same form or a very local refinement. (i.e. stamped sheet metal, composite lay-ups)There are many situations in both aerospace and automotive I would think where sheet of material is stamped and parts are indexed to both sides and sheet metal is accepted using a spec tolerance. 

One method used in the past has been to use ghost parts but it seems like there should be an easier way. What am i missing?

Digital GD&T Webinar - Learn How to Create GD&T in CAD: NX, CATIA and CREO

Digital GD&T Webinar Series Begins This Week - Learn How to Create GD&T in CATIA, NX and CREO

See step by step examples for creating GD&T in CAD in order to support Model Based Definition and Tolerance Analysis

3DCS Software supports Model Based Definition and the use of embedded GD&T. 3DCS is integrated in NX, CATIA and CREO, making it easy to pull that data into your 3DCS model to begin your tolerance analysis.

How to Create Assembly Arrangements in Siemens NX

What are NX Arrangements and How to Create Them

Create different working positions in an assembly arrangement or model using NX

NX Assembly Arrangements allow the user to configure and show different working positions in assembly documentation. This helps in making different views or positions of your model, letting you quickly jump back to those scenarios.

Large NX Models -- Siemens Whitepaper and Helpful Tips for 3DCS Tolerance Analysis

Five Tips for Large Assembly Performance and Tips for Large Models in NX

Included is the link to the Siemens whitepaper Five Tips for Large Assembly Performance and tips for working with large models in NX

Let's be honest, working with large models in any CAD platform can be difficult. DCS has put out a number of videos and webinars to try and help with this, but there is always something else that can be done to simplify a menu, a model, a move or a method. Here are some helpful tips when working in NX on large models, and a great whitepaper from Siemens on the topic.

Checklist: Steps to Create and Validate a 3DCS Tolerance Analysis Model 

Checklist: Steps to Create and Validate a 3DCS Tolerance Analysis Model

Creating accurate models can be difficult. There are a variety of steps and tools that need to be used in order to get results that can be applied to manufacturing with confidence. 

Modeling and simulation are important to reducing costs, but can be intimidating prospects for new users.

3DCS, by its very nature of being an advanced tolerance analysis tool, can be complicated for new users. Many of these users are at a loss when it comes to starting a new model on their own. Here is a checklist to help you with your modeling process.
