The Leading Variation Analysis Solution - What is it?

3DCS Variation Analyst for NX is an integrated software solution integrated into Siemens NX CAD that simulates product assembly and part tolerance 3D stack-ups through Monte Carlo Analysis and High-Low-Mean (Sensitivity) Analysis.

3DCS for NX gives outputs based on part and process variation. These can be input in a variety of ways, from CAD-based PMI to selecting from applicable feature or point-based options in 3DCS. The final results are shown as statistical (Monte Carlo) and mathematics (GeoFactor) based outputs with toggle-able metrics like Cpk, Ppk, ranges, percent out of specification, and a variety more. 

Fully Leverage Your PLM

What helps 3DCS for NX stand out is its connection to Siemen's Teamcenter PLM system. Not only is 3DCS for NX integrated into NX CAD, but it in turn is integrated with Teamcenter. The 3DCS analysis data is stored in the NX CAD model, meaning that any place the model is stored or managed takes the 3DCS data along with it. This makes it easy to store your model and 3DCS data in Teamcenter, handling both version control and data security. 

Why Use CAD Integrated Software?

Integrated CAD tools provide a streamlined approach to analysis that improves adoption, training, and process implementation. With the ability to open 3DCS for NX in the CAD platform, and utilize PMI, GD&T, and CAD characteristics, implementation of 3DCS as a tolerance analysis tool becomes easy to learn and apply.

With an integrated modeling approach, 3DCS saves the analysis data in the model files, letting users manage their CAD model in leading PLM systems like Teamcenter, Windchill, Enovia, and 3DEXPERIENCE and automatically bring their tolerance analysis along. This answers the challenge of both file management and version control.

Model Assembly Process and Part Tolerances - How does 3DCS work?

3DCS for NX uses three methods of simulation;

1. Monte Carlo Simulation

2. High-Low-Median (Sensitivity analysis) 

3. GeoFactor (RSS equation) Analysis

By accurately modeling the assembly, you can see how both the assembly process and the part tolerances contribute to the product's overall variation.  Together, this creates a virtual prototype that can be used to make decisions about design changes and tooling while reducing non-conformance that leads to scrap and rework.

Gain Greater Insight Into Your Design

Simulating products in a digital environment gives engineers the ability to account for variation in key areas; reducing rework, non-conformance, and scrap at final assembly early in the design phase when changes are least expensive.

In addition to this, specifications deemed less critical can be relaxed, increasing tolerances and allowing the use of less expensive manufacturing processes. Creating 3-dimensional tolerance stack-ups let engineers know where to focus when measuring and designing, and the ability to create what-if studies allow them to determine solutions that include both process and part tolerances to keep quality high and costs down.
