Last week Chrysler Group President and CEO Tom LaSorda confirmed that his company had reached an agreement in principle with Chery Sales Co. to distribute Chery-made small vehicles in the NAFTA region, European region, and possibly other global markets. The agreement is subject to the approval of the DaimlerChrysler Supervisory Board and Chinese authorities. Chrysler Group officials say the new vehicles, which will be sold under Chrysler Group brands. The introduction of these new small vehicles represents an important addition to the Chrysler Group's product portfolio. LaSorda said that although historically Chrysler Group has been the most reliant upon trucks,
minivans, and sport-utility vehicles, the company is now moving quickly toward smaller vehicles. Since 2004, Tritec 1.6-liter engines have been exported for use in the Chery A15 and Chery Fengyun. Chrysler Group designers will work with Chery on the new small vehicles, which are based on yet-to-be-announced Chery platforms, to create Chrysler Group styling cues. Chery is becoming a world-class automaker, noted LaSorda, and meeting its goal to be the No. 1 Chinese automaker by 2010. Founded in 1997, Chery is China's largest exporter of domestically made vehicles.

Research and Markets has announced the addition of a new book on Simulation-based Lean Six-Sigma and Design for Six-Sigma. The book concentrates on Six Sigma in simulation environments. For example, axiomatic design, design for X, theory of inventive problem solving (TRIZ), transfer function and scorecards are powerful methods for creating superior service improvements or designs; that is, to do the right things within a comprehensive quality perspective. This book also brings another class of powerful methods in transaction-based simulation arena such as DOE and Lean Manufacturing into its toolbox. The book addresses Simulation-based Six Sigma and Design for Six Sigma and present
approaches to applications via several case studies. The book also provides a solid base for the theoretical and practical aspects of Discrete Event Simulation (DES).

LMS International is in the process of acquiring IMAGINE, a France-based provider of 1-D multiphyics simulation solutions for mechanical and mechatronic systems. Through the acquisition, LMS will extend its portfolio for functional performance simulation and physical testing, delivering a complete set of applications to model, simulate, and test the real-life behavior of mechanical and mechatronic systems. Since its inception in 1986, IMAGINE has provided technology for the mechatronic and control systems simulation markets. Mechatronic system engineering involves electrical and electronic systems for automotive, aerospace, and other mechanical applications. IMAGINE is one
of the first companies in this domain to integrate multiple technologies and mathematic routines which not only save time and effort but can also deliver higher quality simulation results.

In the growing crossover segment, Ford has joined with Airstream to showcase how it could further expand its lineup of expressive crossovers with the Ford Airstream Concept. The concept is powered by a plug-in hydrogen hybrid fuel cell drivetrain -- called HySeries Drive -- that operates under electric power at all times. This advanced fuel cell system is half the weight and cost of today's fuel cells and can operate in the winter. That's a major step forward because today's fuel cells don't do well below freezing. Much like Ford, Airstream began with one man's dream. In 1931, Wally Byam began leveraging aircraft-construction methods to make trailers aimed at
feeding Americans' surging desire to travel. Both companies are influenced by economic and demographic trends -- chiefly baby boomers approaching retirement age. The crossover segment is expected to hit 3 million units by the end of the decade, making it potentially the largest U.S. vehicle segment.

BUNKSPEED, a provider of high-end visualization software and services, announced that Ford Motor Co. used BUNKSPEED’s software to create advanced media images for the Ford Interceptor concept vehicle. In a special collaboration between BUNKSPEED, Ford, and international photographer David Burgess, the team created a collection of digital images of Ford’s car, so media could start reporting on the concept even before it was fully built. Ford already uses BUNKSPEED’s visualization software to render data and see how vehicle designs look – and virtually “drive” in naturally illuminated 2D environments while under development in its global design studios. While other software packages allow automakers to use digital data to create vehicle images, most still require teams of people. With BUNKSPEED’s software, the “production team” was reduced to a crew of one – Burgess. The photographer and his assistant shot backgrounds for the car outside of Las Vegas. Using a spherical camera, they captured a 360-degree environment, including full lighting data. Burgess used his digital camera to shoot back plates of the main area he envisioned for the backdrop of the car. Then, Burgess – who had previously never used BUNKSPEED rendering software – merged the concept car’s data file into
freshly captured environmental image files in just a few hours.

    I want to provide clarification regarding the CoCreate platform and what it means to have a Dynamic Modeling based approach.

    There are two approaches to 3D product development: history-based and Dynamic Modeling based (or history-free). Each approach is different and each has its own benefits and applications for a company. Which is best for an organization is based upon the company, their product, and their product's lifecycle.
    Sometimes the differences between the two, and what it means to be Dynamic Modeling based, is best shown rather than described. In support of this, we created an on-demand webcast that presents the benefits of our approach followed by a product demonstration highlighting the product’s applications and strengths.
    On-demand webcast: http://www.cocreate.com/rd/dd
    The benefits we enable are supported through a long list of customer successes across the high-tech electronics and machinery industries. These stories span the small to mid-size business up to the corporate enterprise. Some feature companies that at first tried a history-based approach and then switched to CoCreate’s platform because of the characteristics of their product development process.
    Success stories: http://www.cocreate.com/success_stories.cfm
    We separate the discussion of history and parametrics. CoCreate also offers parametric capabilities within its product. Parametric relationships are important for some types of product development environments and we recognize that. Rather than having a fully constrained model, CoCreate lets you add them as needed.
    The primary difference between these two approaches is in the geometry creation and modification process. And that comes from either being history-based or Dynamic Modeling based.
    I hope that the above resources help clarify and support CoCreate’s position within the CAD and PLM industry.

    Thanks for the Article Jeff, might be an interesting tool for people that have to work on designs that they did not develop, or if they don't own a Hybrid Modeler like 'all_trades_jack' mentions...
    But for people that design their own products from scratch, there is no doubt in my mind that they would want a history based modeler. Of course that should be one that keeps all previously chosen parameters accessible to future definition and change. If hybrid dynamic modeling was used to modify an existing design the change will hopefully become a parametric history based 'change-feature' until somebody goes and exports to a simple geometric solids description file format and effectively looses the history information again. But lets be aware that having to describe a geometry will almost certainly take much more storage space than to only have to store the object tree of the historic creation and modification of 'features'. And don't even imagine having to modify applied patterns repeated many times, or changing your mind about an earlier applied feature! So if you want to be able to reuse your designs, create parametric variations and exploratively try out things; don't flush your investment! Keep your History!

    The article explains what history-based (parametric) modeling is, but does not explain what CoCreate's "Dynamic Modeling" is. So, the claims that Dynamic Modeling are superior are just that: claims. No substance.
    Also, the buttons in the page to go to the next page make no sense. One seems to jump to some other random article, rather than a continuation of the existing article.

    As a user who moved from Solidworks to CoCreate due to a job change, here's a hands on perspective. It honestly took a day of training for me to 'get' what CoCreate means by history free or dynamic modeling. But now there is no chance I'm going back to history based modeling. On almost every project before using CoCreate, I *hated* changing requirements, especially those we did not plan for (most of them). Inevitably, 'just one more change' and the model would break and I'd start from scratch rather than try to fix it. That always meant working later at night than planned. But with CoCreate OSDM, they've managed to put a ton of intelligence into thier modeler and somehow elimated the history tree (I still don't get how, but it is amazing). OneSpace Designer Modeling is a parametic modeler, it's just a history free one, which is great. It's the best of both worlds. And I can even open up files from all kinds of other tools and edit them as if I deisnged them myself (absolutely amazing). As for Taylor (All Trades Jack) above who is a Product Manager for UGS/NX, better take a closer look at OSDM before ripping on it. Your statements are like saying that Windows is antiquated based on looking back at Windows version 3.1. I watched the video and you should too.

    It's always interesting to watch companies that have been left behind in the dust technologically market their antiquated solution as "revolutionary." Non-parametric modeling used to be the *only* way to work. While I can see the advantage in a hybrid system (like NX from UGS) that allows both parametric modeling and direct manipulation of the geometry, The CoCreate claim that parametrics are completely useless is just plain silly. "Retro" is kinda cool for living room furniture, but certainly less desirable in a mainstream design tool.
