Engineers and social-networking sites

It seems engineers are increasingly using social-networking sites. I’ve even heard that PLM companies are considering embedding social elements such as microblogs and Wikis into their systems. Do you use any of the sites? If so, what are the advantages over more conventional means of communication? (I use Linkedin, Second Life, and Twitter, as well as a few IMs). Twitter, for example, is a nifty way to communicate with colleagues anywhere in the world, off-the-cuff.

Eighth-grade engineers

Who says we lack an upcoming generation of engineers? Eighth graders at Our Lady of Guadalupe Middle School in Detroit, Mich., are learning such sophisticated terms as:


* active dimension


A dimensional callout in a drawing that is linked to a dimensional constraint in a design


* active sketch


The sketch that is enabled as the site of object creation or modification. It is indicated in the design object browser by bold type face.


* active workplane


The workplane containing the active sketch. It is indicated in the design object browser by bold type face.


* add-in


A user-created program that uses the Pro/DESKTOP functionality. It is structured as an ActiveX program. See also macro.


* angled workplane


A workplane created with a defined angular orientation relative to a datum object.


* assembly


A design file that has components added to it from other design files. An assembly may be used as a component in a higher-level assembly.


* associativity


The parametric relationships shared by objects. A change in one object can induce changes in the other, or be controlled by constraints on the other object. For example, if a hole is driven by the diameter of a shaft, and the shaft diameter changes, then the hole changes automatically.


* attraction point


A black square that appears on a sketch object when prehighlighted in creation mode. Indicates the location where a new object would attach to the prehighlighted object, if you clicked and dragged at that point.

I changed my mind


There is a new anthology out called What Have You Changed Your Mind About? (Harper Perennial), in which 150 “big thinkers” describe what they now think they were wrong about earlier in their lives. Much of this has to do with technology and education. Some of the more interesting flip-flops come from Ray Kurzweil, who no longer believes in extraterrestrials, and AI researcher Roger C. Schank who no longer thinks we’ll have thinking machines as smart as we are in his lifetime.

Interestingly, no one I noticed mentioned changing their mind about George W. Bush.

View on the non-bailout from Detroit and the Washington beltway.

I went to school in the Detroit area and I still have friends who work in the auto industry. So I have been watching the auto bailout proceedings with some interest. This morning I got the following email from a buddy who has spent his career designing vehicles. I reproduce it here for general interest.


I also got a press release today from the U.S. Business and Industry Council, which I am also posting here. They have an interesting take on Tennessee Sen. Bob Corker, the Great Skeptic of the auto rescue.


=================================================


I will spend my day forwarding this to every Republican Senator that voted against the loan. I will then forward it to every journalist I can find an email for. I will then forward it to everyone I know asking them to do the same. I’m mad as hell and won’t take it any more…..

“Letter to the Editor” a Ford dealership owner to The Inter-Mountain.


Editor:


As I watch the coverage of the fate of the U.S. auto industry, one alarming and frustrating fact hits me right between the eyes. The fate of our nation’s economic survival is in the hands of some congressmen who are completely out of touch and act without knowledge of an industry that affects almost every person in our nation. The same lack of knowledge is shared with many journalists whom are irresponsible when influencing the opinion of millions of viewers.


Sen. Richard Shelby of Alabama has doomed the industry, calling it a dinosaur. No Mr. Shelby, you are the dinosaur, with ideas stuck in the ’70s, ’80s and ’90s. You and the uninformed journalist and senators that hold onto myths that are not relevant in today’s world.


When you say that the Big Three build vehicles nobody wants to buy, you must have overlooked that GM outsold Toyota by about 1.2 million vehicles in the U.S. and Ford outsold Honda by 850,000 and Nissan by 1.2 million in the U.S. GM was the world’s No. 1 automaker beating Toyota by 3,000 units.


When you claim inferior quality comes from the Big Three, did you realize that Chevy makes the Malibu and Ford makes the Fusion that were both rated over the Camry and Accord by J.D. Power independent survey on initial quality? Did you bother to read the Consumer Report that rated Ford on par with good Japanese automakers.


Did you realize Big Three’s gas guzzlers include the 33 mpg Malibu that beats the Accord. And for ‘09 Ford introduces the Hybrid Fusion whose 39 mpg is the best midsize, beating the Camry Hybrid. Ford’s Focus beats the Corolla and Chevy’s Cobalt beats the Civic.


When you ask how many times are we going to bail them out you must be referring to 1980. The only Big Three bailout was Chrysler, who paid back


$1 billion, plus interest. GM and Ford have never received government aid.


When you criticize the Big Three for building so many pickups, surely you’ve noticed the attempts Toyota and Nissan have made spending billions to try to get a piece of that pie. Perhaps it bothers you that for 31 straight years Ford’s F-Series has been the best selling vehicle. Ford and GM have dominated this market and when you see the new ‘09 F-150 you’ll agree this won’t change soon.


Did you realize that both GM and Ford offer more hybrid models than Nissan or Honda. Between 2005 and 2007, Ford alone has invested more than $22 billion in research and development of technologies such as Eco Boost, flex fuel, clean diesel, hybrids, plug in hybrids and hydrogen cars.


It’s 2008 and the quality of the vehicles coming out of Detroit are once again the best in the world.


Perhaps Sen. Shelby isn’t really that blind. Maybe he realizes the quality shift to American. Maybe it’s the fact that his state of Alabama has given so much to land factories from Honda, Hyundai and Mercedes Benz that he is more concerned about their continued growth than he is about the people of our country. Sen. Shelby’s disdain for ‘government subsidies’ is very hypocritical. In the early ’90s he was the driving force behind a $253 million incentive package to Mercedes. Plus, Alabama agreed to purchase 2,500 vehicles from Mercedes. While the bridge loan the Big Three is requesting will be paid back, Alabama’s $180,000-plus per job was pure incentive. Sen. Shelby, not only are you out of touch, you are a self-serving hypocrite, who is prepared to ruin our nation because of lack of knowledge and lack of due diligence in making your opinions and decisions.


After 9/11, the Detroit Three and Harley Davidson gave $40 million-plus emergency vehicles to the recovery efforts. What was given to the 9/11 relief effort by the Asian and European Auto Manufactures? $0 Nada. Zip!


We live in a world of free trade, world economy and we have not been able to produce products as cost efficiently. While the governments of other auto producing nations subsidize their automakers, our government may be ready to force its demise. While our automakers have paid union wages, benefits and legacy debt, our Asian competitors employ cheap labor. We are at an extreme disadvantage in production cost. Although many UAW concessions begin in 2010, many lawmakers think it’s not enough.


Some point the blame to corporate management. I would like to speak of Ford Motor Co. The company has streamlined by reducing our workforce by 51,000 since 2005, closing 17 plants and cutting expenses. Product and future product is excellent and the company is focused on one Ford. This is a company poised for success. Ford product quality and corporate management have improved light years since the nightmare of Jacques Nasser. Thank you Alan Mulally and the best auto company management team in the business.


The financial collapse caused by the secondary mortgage fiasco and the greed of Wall Street has led to a $700 billion bailout of the industry that created the problem. AIG spent nearly $1 million on three company excursions to lavish resorts and hunting destinations. Paulson is saying no to $250 billion foreclosure relief and the whole thing is a mess. So when the Big Three ask for 4 percent of that of the $700 billion, $25 billion to save the country’s largest industry, there is obviously oppositions. But does it make sense to reward the culprits of the problem with $700 billion unconditionally, and ignore the victims?


As a Ford dealer, I feel our portion of the $25 billion will never be touched and is not necessary. Ford currently has $29 billion of liquidity.


However, the effect of a bankruptcy by GM will hurt the suppliers we all do business with. A Chapter 11 bankruptcy by any manufacture would cost retirees their health care and retirements. Chances are GM would recover from Chapter 11 with a better business plan with much less expense. So who foots the bill if GM or all three go Chapter 11? All that extra health care, unemployment, loss of tax base and some forgiven debt goes back to the taxpayer, us. With no chance of repayment, this would be much worse than a loan with the intent of repayment.


So while it is debatable whether a loan or Chapter 11 is better for the Big Three, a $25 billion loan is definitely better for the taxpayers and the economy of our country.


So I’ll end where I began on the quality of the products of Detroit. Before you, Mr. or Ms. Journalist continue to misinform the American public and turn them against one of the great industries that helped build this nation, I must ask you one question. Before you, Mr. or Madam Congressman vote to end health care and retirement benefits for 1 million retirees, eliminate 2.5 million of our nation’s jobs, lose the technology that will lead us in the future and create an economic disaster including hundreds of billions of tax dollars lost, I ask this question not in the rhetorical sense. I ask it in the sincere, literal way. Can you tell me, have you driven a Ford lately?

Dear Folks,


Is Tennessee Sen. Bob Corker, the Great Skeptic of the auto rescue, simply opposed to government support for key industries? Or is he simply opposed to the government support for U.S.-owned industries? You’ll see revealing answers in the item below, which will be posted shortly on the U.S. Business and Industry Council’s www.AmericanEconomicAlert.org website.


USBIC Research Fellow Alan Tonelson, the author, is available for interviews on this item at 202-266-3985 (office direct dial) and 202-746-9366 (cell). Interviews can also be arranged by calling me at 202-266-3989.


We hope you find this item and its revelations useful for your ongoing coverage of auto industry news.


Sincerely,

Globalization Follies:


CORKER’S AMERICANS-LAST AUTO POLICIES


How ironic was it of Senate Republicans to choose Bob Corker of Tennessee as their point man for torpedoing a realistic auto industry restructuring package? Let us count the ways.


Corker has strongly voiced skepticism about committing federal tax dollars to avert disastrous bankruptcies of the Big Three U.S.-owned vehicle makers – not to mention of the countless suppliers they would drag down with them, But he has enthusiastically supported spending Tennessee taxpayer dollars to pay foreign-owned automakers to set up shop in his home state. Thus in 1995, Tennessee gave Nissan a $197 million incentive package to relocate its North American headquarters to Franklin. And just last summer – bare months before scuttling emergency loans for Detroit – Corker helped the state throw $577.4 million more at Volkswagen to build a $1 billion plant in near Chattanooga – possibly the largest ever such giveaway to an automaker.


The story of the Volkswagen package are especially revealing. Despite Corker’s emphasis on protecting the public purse, he and other Tennessee officials offered the incentives before they could specify the final costs. They used state workers and equipment to hurriedly clear the 500-acre factory site, wined and dined Volkswagen officials at least half a dozen times, and capitalized all the while on the programs and capabilities of the Tennessee Valley Authority – the quintessential New Deal-era Big Government program.


To add insult to injury, although Corker and his U.S. Senate colleagues have blasted the Detroit rescue as a futile effort to prop up industrial losers, the Volkswagen company that they courted is 20 percent owned by the German state of Lower Saxony, has lost money in the United States since 2002, and controls a grand total of two percent of the U.S. vehicle market.


Corker has called his proposals “landmark” and “historic.” We at GLOBALIZATION FOLLIES agree: We can’t think of a precedent for a U.S. leader so proudly putting American companies and workers last.

That’s not art!

In this month’s CAD/CAM e-newsletter, I featured a granite sculpture that currently resides in the Autodesk Gallery at One Market in San Francisco. According to the developer, the gallery contains the work of “visionary artists, architects, engineers, consumer-product designers, and students.” I thought the design was kind of cool and said it probably would not have been possible without CAD.


A few readers got me to rethink whether the sculpture is actually “art,” or even that visionary. Kwong Wong writes: “Please don’t take this the wrong way, but how does putting together a wacky shape in a 3D design package and then having a shop in China (or anywhere else for that matter) carve it out of granite count as “Art Work.” Along those lines, having a bolt designed in a CAD package and machined with CAM process seems to be even better artwork with greater discipline. Anyone who has played with a CAD package probably has pulled library shapes and assembled a few things at random and as I see it, this “Art” exhibits the same depth of thought.”


And Dimitri Galitzine from Design Development Associates LLC points out that a non-profit entity has already been providing a full-service stone-sculpture fabrication-facility for artists, architects, and designers.


Now that I think of it, the old art of signmaking went by the wayside years ago, with CAD driving automated routers. So what’s the big deal about cutting a cement sculpture?

Old DWG, New BIM?

CAD at the Venetian Resort


Autodesk is again hosting its annual Autodesk University (AU) event at the Venetian Resort in Las Vegas. It’s still pretty early, so things haven’t yet geared up. The developer must have sympathy for those of us who travel a distance to get here and thus are still reeling from jetlag — the keynote speech from CEO Carl Bass is not slated to start until around

10 am! Most similar venues have attendees getting up around 7 am.


Anyway, I absolutely love the Venetian Resort, especially the fake “Venice” that comprises a series of fancy shops and resturants, a real canal full of real water, and gondoliers dressed in the traditional red and white striped shirts. Some of my collegues hate Las Vegas because it is so sleazy. I don’t gamble but I love the neon lights and the glitter. But you can sense a heart of darkness: I’ve been told that there are shops where desperate gamblers can pawn their cars, recreational vehicles, and even home mortgages.


Old DWG, New BIM


At the registration area is a large board that attendees can use to post their idea on how to get a more sustainable


world. Ideas: Share our vehicles, Go local; Turn off the lights; Build digitally; Use solar wind and energy. And — my favorite — “Old .DWG, new BIM.” BIM is a big buzz in architectural circles lately. It stands for Building Information Modeling and is said to be a term that was coined by Autodesk to mean “3D, object-oriented, AEC-specific CAD.” Of course, DWG is the traditional drawing format. Can you teach an old DWG new tricks, er, that is to be a BIM?


Ideas on Innovation


Tom Kelly, co-founder of design company IDEO spoke at this morning’s keynote session. He says, design is not superficial, it is strategic. It creates value. It can make the difference between love and hate. If you wanna’ innovate, you have to design. Now you have to out-innovate the rest of the world. It is like the Red Queen effect from Alice in Wonderland. We are running, but we are not getting anywhere. So you have to run twice as fast. What if we are first, or perhaps the best? IDEO designs: From the Apple mouse to helping the Red Cross redesign the experience of donating blood.


What works in innovation and what doesn’t? His book: The Ten Faces of Innovation. Learn from other people’s failures. His mistake: The human brain can handle only 7 bits of information at a time. So don’t talk about the 10 top faces…. talk about the 2:


Designs used to be driven by specifications and technical challenges. The Anthropologist would go to lakes and streams and come and tell us about it. This is a source of innovation. The act of discover is in seeing with new eyes. In the process of developing expertise, most designers start filtering out new experiences. Vuga de — the opposite of deja vu. Start to ask questions differently. For example, Oral B wanted to innovate around kid’s toothbrushes. IDEO started with anthropology — every toothbrush in the world had the implicit assumption that kids’ toothbrushes should be a small version of their parents. Kids actually hold toothbrushes differently and needed big, squishy toothbrushes. Had best selling toothbrush in the world for 18 months until others caught up.


Next is the Experience Architect. He thinks about the total experience the customer has. Good book — The Experience Economy.


For example making a birthday cake:


Commodity way — Mom goes out and buys stuff to make a birthday cake. Cheap, but a lot of work and a lot of risk.


Product way — Betty Crocker makes the batter. More expensive, but saves a lot of time.


Service level — Go to a bakery and buy a ready-made cake that squirts the kid’s name on it. No risk. Expensive


Chuckie Cheeses — Terrible in many ways except you can be a hero for your kids that day if you pay big bucks for a Chuckie Cheese party. Parents are willing to pay almost anything. No risk.


How to get an idea: Find an opportunity hidden in plain sight. For instance, the Westin Hotel and its Heavenly Bed. No one else had thought to design around the businessmen who flies in late, goes to bed and goes to work early (not around the spa and pool crowd).


Use simplicity as a tool. The simpler as the better. Aspire to the “wet-nap interface” of moist towelettes. Just tear open and use.
