The document provides information on 3DCS Variation Analyst software which is fully integrated into the PTC Creo CAD platform. Some key points:
- 3DCS models are stored directly in Creo assembly files without data translation, allowing direct use of Creo CAD.
- 3DCS leverages Creo's assembly structure and allows extraction and use of Creo GD&T, joints, and constraints.
- 3DCS requires an assembly structure and write access to the top Creo assembly file for data storage. It does not work with single Creo parts.
CATIA Integrated Tolerance Analysis - 3DCS for CATIA V5Benjamin Reese
3DCS Variation Analyst CAA V5 Based Software is used by manufacturers across the globe for Tolerance Analysis to reduce scrap, rework and warranty claims.
3DCS Variation Analyst CAA V5 Based (3DCS for V5) is an integrated software solution in CATIA V5 that simulates product assembly and part tolerance 3D stack-ups through Monte Carlo Analysis and High-Low-Mean (Sensitivity) Analysis.
Model Part and Process Variation - How does it work?
Use CATIA FTA - Embedded GD&T3DCS for V5 uses three methods of simulation; Monte Carlo Simulation, High-Low-Mean (Sensitivity analysis) and GeoFactor Analysis. These together highlight the sources of variation as well as potential build issues in the product.
By accurately modeling the build process, users can determine how their process will affect the assembly in addition to their part tolerance stack-up. This together essentially creates a virtual prototype that can be used to make decisions about design changes and tooling while reducing scrap and rework.

3DCS Dimensional Variation Analysis Integrated in Siemens NX CADBenjamin Reese
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.
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.

Introduction to the OMG Systems Modeling Language (SysML), Version 2Ed Seidewitz
Tutorial presented at the MODELS 2020 virtual conference on the proposed OMG Systems Modeling Language, Version 2, as of the initial submission of the specification.
SysML v2 and the Next Generation of Modeling LanguagesEd Seidewitz
The Systems Modeling Language (SysML) is a particularly successful offshoot of the Unified Modeling Language (UML) tailored for Model-Based Systems Engineering. After a decade of growing use of SysML, in 2017 the Object Management Group (OMG) issued a Request for Proposals (RFP) for a new version of the language. A year into the ongoing work to respond to this RFP, it is clear that SysML v2 needs to be more than just an expansion of the functional capabilities of SysML. Rather, it must address fundamental architectural issues that have made it difficult to further evolve SysML v1 to address the needs of its user community. Therefore, the language is being re-designed using a new kernel metamodel with formally grounded semantics. This kernel can then be extended using semantic model libraries, rather than by expanding the language metamodel itself. This approach will allow SysML v2 to be not only the modeling language for traditional systems engineering, but also the foundation for a whole new generation of modeling languages.

Multi domain product architecture: start integrated, stay integratedObeo
A comprehensive product architecture is critical to cross-domain product development
The electronics industry adage '90% of the components work as designed but 50% fail when you plug them in' is multiplied as you bring together electronics, software, and mechanics in today's complex products.
Preventing these types of cross-product integration problems requires a cross-domain level of thinking supported by integrated Model-Based System Engineering (MBSE)
and architecting solutions that can be continuously verified and validated through simulations to identify issues early.
Based on Capella, and integrated with Teamcenter, System Modeling Workbench provides an integrated multi-domain product architecture that enables a cross-domain digital thread: 'start integrated, stay integrated'.
This webinar was driven by Pascal Vera (Siemens Digital Industries Software):
Pascal Vera is Product Management Director at Siemens Digital Industries Software, responsible for MBSE and ALM, and work in the team managing the partnership with Obeo for Capella integration with Teamcenter.
Holding a doctoral degree in industrial software engineering, he has 20+ years of experience in Systems Engineering, Mechatronics and Embedded Systems across multiple industries.
System Modeling Workbench is a joint development of Obeo and Siemens Digital Industries Software.
Today's fast paced product market has shorter lifecycles and tighter budgetary concerns. Tolerance analysis software provides an ideal solution to reduce the number of crucial steps needed to optimize a product at the design step itself. 3DCS Variation Analyst is the world's most used tolerance analysis software that is fully integrated into NX/ CATIA V5/ Creo and CAD Neutral Multi-CAD. 3DCS Variation Analyst is designed to use a consistent format and set of mathematical formulae that create reliable results, enabling engineers to gain a complete insight into their design. The software empowers design engineers to control variation and optimize their designs to account for inherent process and part variation, which in turn reduces non-conformance, scrap, rework and other associated costs.
3DCS Variation Analyst
Used by the world’s leading manufacturing OEM’s to reduce the cost of quality, 3DCS Variation Analyst comes in two flavours:
1) 3DCS Variation Analyst (NX / CAA V5 or Creo Based) is an integrated solution for NX / CATIA V5 or Creo. Since it is an integrated solution, users can not only activate 3DCS workbenches from within the modelling solution, they can use many of its inbuilt functionality to support their modelling.
3DCS Variation Analyst provides three analysis methods:
Monte Carlo Analysis
High-Low-Mean (Sensitivity Analysis) and
Geofactor Analysis (Relationship)
3DCS FEA Compliant Modeler - Finite Element Analysis and Tolerance AnalysisBenjamin Reese
Traditional variation analysis methods are considered to be "rigid-body" or "non-compliant" modeling; meaning, that every part within the assembly does not flex or would not be distorted through an assembly process such as welding, clamping or unclamping of an assembly fixture.
While this might be the case with a few machined components, most commodities and materials like sheet metal, plastics, aluminum, etc. can be heavily influenced through the manufacturing processes (both fabrication and assembly), thus changing the dimensional integrity or shape of the part/assembly. Finite Element Analysis (FEA) is used to determine the stresses and displacements in mechanical objects and systems and is the basis for this leading-edge advancement in predictive analysis.
3DCS FEA Compliant Modeler, an add-on module to the 3DCS software solutions, utilizes FEA methods to accurately simulate the variation of compliant parts and assemblies within the 3D Variation Analysis model.

Optimize Assembly and Manufacturing Processes
Determine optimal placement and order of operation for processes
When welding, bolting, riveting or assembling parts, the order and the process can have as much of an effect on final results as the parts themselves. Riveting can stretch aircraft aluminum skin, assembling can bend and cause spring back, and bolting can warp materials. Simulate, test and determine the best order of operations and the impact these processes will have on your parts.

Additive manufacturing (AM) or 3D printing is maturing rapidly as a viable solution of make optimized parts for “real engineering” applications. The freedom of design that is achievable using AM process is un parallel in terms of reducing structural weight, reducing material cost, generating complex shapes and connections and introducing directional properties in a component. However, understanding of AM process and utilizing process parameters to optimize a design comes with many challenges. Currently, one of the emphasize is to use physics based realistic simulation to replicate the AM process numerically and relate process parameters to the concept of functional generative design that relates design with manufacturing process.
Current work, through a typical build example, discusses an integrated numerical solution on a digital platform that involves the following.
Generative Design involving topology optimization that creates parts in context of the manufacturing process and automatically generate variants of conceptual and detailed organic shapes that helps make informed business decisions based on physics-based analytic tools. Process planning that defines and customizes manufacturing environment including nesting parts automatically on the build tray, designing and generating optimal support structures, and creating machine specific slicing and scan path which is ready for print. Process simulation that automatically includes machine inputs for energy, material and supports into the simulation at layer, part and build levels for any additive manufacturing process and accurately predicts part distortions, residual stresses and as-built material behavior. Finally, the platform involves post processing to perform shape optimization where simulation is used to guide support-structure strategy for enhanced build yield, compensate distortion effects without the need to redesign the product tooling, produce high-quality morphed surface geometry with unchanged topology, and perform final in-service performance validations of manufactured part.

Worst Case Tolerance Analysis - What is it, why do it, and how?Benjamin Reese
From the DCS Webinar on Worst Case: http://mkt.3dcs.com/worst-case-tolerance-analysis-webinar
Worst Case tolerance analysis is where each individual tolerance is set to a point in its range (typically a tolerance limit) where it will result in either the maximum or minimum output at a specific measured location.
A Worst Case analysis is the only way to guarantee that an assembly of good detail parts will not be out of specification.
However, in most cases, a statistical analysis gives the results needed to make decisions and reduce manufacturing costs.

Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

The main purpose of the tolerance analysis was to assure and improve final product quality. The analysis results justified the need of
design changes to accommodate dimensional variation. The amount of predicted variation identified the need to change gap and seal
specifications as well as helped optimize hinge designs to guarantee no pre-stress and increased product life. The software also
supported the definition of pre-manufactured shims now used in production. 3DCS also helped Embraer find possibilities to use
“coordinated assembly” minimizing tooling which lowered production costs with guaranteed product quality. Additionally, tolerance
analysis and simulation techniques motivated and supported process development strategies to guarantee process variation
compensation on composite tooling design.
Daniel C. da Silva, Embraer Tolerance Analysis Team Leader “The 3DCS technology brought our commitment to product quality and safety by
design to an even higher level. The tool not only can quantify our technical decisions but truly helps our IPD
teams to numerically and visually discuss spatial dimensional variations and its management early in the design phase. These facts, together with
an integrated Catia V5 environment, intensive technical training and the DCS top support and development service were the key to our success in
this custom development for JetBlue, one of our key EMBRAER 190 customers.”
“The Live TV Radome (radar dome) is used to protect the
antenna, which sits on top of the E190 fuselage. The
structural Radome assembly consists of about 50 parts with
over 150 key tolerance specifications. It was Embraer’s first
production usage of 3DCS … software on a totally new
development project.”

Variation Analysis
Issue: Variation of Internal components of laptop causing assembly build issues
– hard drive, mother board, ram chips, etc… - Limited space inside of Laptop case
creates very little room for variation. Changes in components from manufacturing
variation were causing cases where the components did not all fit inside the case.
Solution: Simulating the assembly sequence with variation taken into account provided
new insight into the source of the variation and primary trouble areas.
Results: With basic design changes to the placement of the components, the current
amount of variation was accounted for, requiring very little adjustment in tolerances.

Issue: Shock was freezing up when
placed under larger forces, such as a
jump or heavy landing.
Solution: Using 3DCS Mechanical, the
shock was simulated with variation from
manufacturing as well as assembly
processes and through a large range of
different forces.
Results: At higher levels of force, the shock was seizing from a variation build up
connecting with the spring system. This was unforeseen as it stemmed more from
process than part tolerancing. A minor adjustment to the process negated the
problem, using simulation to validate.

Results: Using AAO, tolerances and features that were not key
to quality had their tolerances opened up, while key areas were
tightened to improve assemble-ability. This overall reduction in
manufacturing costs had a positive outcome on overall product
cost.
Editor's Notes
A Monte Carlo Simulation will tell if the results of a measurement are "good" or "bad." It works by simulating thousands of builds using virtual parts and collecting data for each build. The simulation randomly varies tolerances within specified ranges to all parts, assembles the parts as defined in the build sequence, and then takes measurements for desired outputs. This sequence is repeated a specified number of times to populate a statistical distribution. The simulation output is presented as a histogram and statistical data for each defined measurement. The histogram plots the frequency that a measurement value should fall within a certain interval. The width of the histogram represents the range of variation of that measurement over all of the simulated builds. The user-defined specification limits signify the acceptable manufacturing range. From the simulation results, the mean, standard deviation, distribution, and other statistics can be determined per measurement.
This process is repeated for all toleranced features. When a specific tolerance is varied and results in a larger value for a given measurement, the measurement is considered to be more sensitive to that particular tolerance. Each contributor percentage is calculated based on corresponding measurement values at High, Low, Median, and Nominal. HLM Sensitivity lists the contributors to variation in descending order. Changing a tolerance at the top of the list will have a greater impact on the measurement than changing a tolerance at the bottom of the list. Be aware that while a tolerance may have a small contribution to one measurement, its contribution to other measurements may be large.
Similar to the High-Low-Median sensitivity analysis, GeoFactor examines the effect of each tolerance on a given measurement. Unlike HLM sensitivity, which analyzes the range of a tolerance, GeoFactor analysis examines the contribution of the tolerance based on geometry effect. To represent this effect, the result is given as a G Factor. The G Factor is the geometric multiplier of each tolerance in a measurement. If a tolerance has a G Factor < 1, it will mitigate the tolerance's contribution to the variation in the measurement. If the G Factor is > 1, it will amplify the tolerance's contribution to the variation in the measurement. Picture a lever where one side is controlled and the other side is measured. If the fulcrum is centered, the G Factor will be 1 because the measured side will vary with the same range as the controlled side. As the fulcrum moves nearer to the controlled side, the measured side will vary more than the controlled side. Thus, the G Factor will increase. As the fulcrum moves further from the controlled side, the measured side will vary less than the controlled side. Thus, the G Factor will decrease. GeoFactor can help you decide whether changing locators or geometry would be advantageous to improving design. Ideally, a model will have the smallest G Factors possible to mitigate variation.
The first requirement of a 3DCS Variation Analysis model is the nominal part geometry. This can include parts and assemblies from most CAD programs including CATIA, SolidWorks, and NX. The top level assembly is imported into the 3DCS software and is ready for analysis. If the nominal geometry does not exist yet or is incomplete, points can be used to represent features in place of the CAD geometry. This is common to represent tooling in an assembly. Points can also be used to test design changes before the effort is made to update the CAD data. This is an advantage to optimize the design before the geometry is finalized. Old parts can be swapped out for new parts as the design is updated without losing any information already created in the model.
The next couple of slides you will see a couple of success stories of TA use within General Motors.
As noted by Rich Korynski TA Manager, the product execution (Tolerance Analysis) has provided them the toolset to deliver four Car/Truck of the Year awards recently!
If you look at these vehicles you will see very aesthetically pleasing and quality fit/finish vehicles.
As mentioned earlier Tolerance Analysis can be used for so many different assembly types. In this case General Motors has used Tolerance Analysis modeling for such studies as ...
Engine Combustion Variation (compression ratio)
Accessory Drive Belt System
Chain Drive and Valve train kinematics
Direct-Injection Fuel Injection System
Studies in Sensor Variation
Many packaging/clearance studies between components
Interface/Joint studies between components (fasteners and port alignments)
In-vehicle engine compartment packaging
As a result of these efforts the GM EcoTec engine was awarded by Wards Auto Magazine “one of the Top 10 engines for 2010.”
Chrysler’s approach to the “Closed-Loop” is what they refer to as the PQP Loop which has enabled them to improve their vehicle “fit” and “finish”.
Critical to Quality and Fit
Once the numbers are crunched, the fabricating machines are set accordingly. “The GD&T we used to develop this final interior has enabled the best craftsmanship and cabin experience in the industry,” enthuses [Jay Beever, vice president of marketing and interior design].
