catia to solidworks

A few weeks back I mentioned how I was confused as to why a CATIA translator in SolidWorks did not make the Top Ten list at SolidWorks WORLD this year. That one sentence began a firestorm of tweets about whether the translator was really a high priority among SolidWorks users.

First and foremost I need to mention that I live in West Michigan which is heavily entrenched in the auto industry. With that being said, almost everywhere I go and everyone I talk to in the Midwest have mentioned the NEED for the ability of SolidWorks to handle CATIA files natively. After all, both CAD programs are owned by parent company Dassault Systems.

One of the first comments made on Twitter stated the my feedback and the user base I usually talk to might be skewed compared to the entire SolidWorks user base and I totally agree with the comment. This may be the exact reason why it does not make it to the Top Ten list.

Still it leads to me think, what is the holdup of getting this translator incorporated into SolidWorks? There are many tools inside SolidWorks that are industry specific, things like Mold tools. So why should someone that has to constantly deal with CATIA files be forced to find workarounds in order to get their work done.

I personally know of a company that has a large number of SolidWorks licenses, however they also have a license of Autodesk Inventor for the sole reason of translating data. I am guessing that this is probably not how Dassault Systemes wants there customers working.

So what is the holdup? Is it pride? Is it the possibility of making more money by releasing an additional add in down the road that customers are going to have to buy? I don’t know the reasoning for it not being in the software already but I have to think that one of these is the deep rooted holdup. When or if it does come I sure hope that it does not come at an additional cost if you have the Professional or Premium SolidWorks packages.

This post is not meant to pick on Dassault Systemes, SolidWorks, a development team, or a specific development person but is more to ask the question of why are we still waiting. SolidWorks 2011 offers a wide range of translators for other popular CAD programs like Pro-E, Unigraphics, Inventor, Solid Edge, etc. but not CATIA yet.

Do you see the need? Why do you think we are still waiting?

Power for Electronic ‘Super Skin’


Power for Electronic ‘Super Skin’

By Louis Bergeron, Stanford University

Thursday, March 10, 2011

The foundation for the artificial skin is a flexible organic transistor, made with flexible polymers and carbon-based materials.

"Super skin" is what Stanford researcher Zhenan Bao wants to create. She’s already developed a flexible sensor that is so sensitive to pressure it can feel a fly touch down. Now she’s working to add the ability to detect chemicals and sense various kinds of biological molecules. She’s also making the skin self-powering, using polymer solar cells to generate electricity. And the new solar cells are not just flexible, but stretchable – they can be stretched up to 30 percent beyond their original length and snap back without any damage or loss of power.

Super skin, indeed.

"With artificial skin, we can basically incorporate any function we desire," said Bao, a professor of chemical engineering. "That is why I call our skin ‘super skin.’ It is much more than what we think of as normal skin."

The foundation for the artificial skin is a flexible organic transistor, made with flexible polymers and carbon-based materials. To allow touch sensing, the transistor contains a thin, highly elastic rubber layer, molded into a grid of tiny inverted pyramids. When pressed, this layer changes thickness, which changes the current flow through the transistor. The sensors have from several hundred thousand to 25 million pyramids per square centimeter, corresponding to the desired level of sensitivity.

To sense a particular biological molecule, the surface of the transistor has to be coated with another molecule to which the first one will bind when it comes into contact. The coating layer only needs to be a nanometer or two thick.

"Depending on what kind of material we put on the sensors and how we modify the semiconducting material in the transistor, we can adjust the sensors to sense chemicals or biological material," she said.

Bao’s team has successfully demonstrated the concept by detecting a certain kind of DNA. The researchers are now working on extending the technique to detect proteins, which could prove useful for medical diagnostics purposes.

"For any particular disease, there are usually one or more specific proteins associated with it – called biomarkers – that are akin to a ‘smoking gun,’ and detecting those protein biomarkers will allow us to diagnose the disease," Bao said.

The same approach would allow the sensors to detect chemicals, she said. By adjusting aspects of the transistor structure, the super skin can detect chemical substances in either vapor or liquid environments.

Regardless of what the sensors are detecting, they have to transmit electronic signals to get their data to the processing center, whether it is a human brain or a computer.

Having the sensors run on the sun’s energy makes generating the needed power simpler than using batteries or hooking up to the electrical grid, allowing the sensors to be lighter and more mobile. And having solar cells that are stretchable opens up other applications.

A recent research paper by Bao, describing the stretchable solar cells, will appear in an upcoming issue of Advanced Materials. The paper details the ability of the cells to be stretched in one direction, but she said her group has since demonstrated that the cells can be designed to stretch along two axes.

The cells have a wavy microstructure that extends like an accordion when stretched. A liquid metal electrode conforms to the wavy surface of the device in both its relaxed and stretched states.

"One of the applications where stretchable solar cells would be useful is in fabrics for uniforms and other clothes," said Darren Lipomi, a postdoctoral fellow in Bao’s lab and lead author of the paper.

"There are parts of the body, at the elbow for example, where movement stretches the skin and clothes," he said. "A device that was only flexible, not stretchable, would crack if bonded to parts of machines or of the body that extend when moved." Stretchability would be useful in bonding solar cells to curved surfaces without cracking or wrinkling, such as the exteriors of cars, lenses and architectural elements.

The solar cells continue to generate electricity while they are stretched out, producing a continuous flow of electricity for data transmission from the sensors.

Bao said she sees the super skin as much more than a super mimic of human skin; it could allow robots or other devices to perform functions beyond what human skin can do.

"You can imagine a robot hand that can be used to touch some liquid and detect certain markers or a certain protein that is associated with some kind of disease and the robot will be able to effectively say, ‘Oh, this person has that disease,’" she said. "Or the robot might touch the sweat from somebody and be able to say, ‘Oh, this person is drunk.’"

Finally, Bao has figured out how to replace the materials used in earlier versions of the transistor with biodegradable materials. Now, not only will the super skin be more versatile and powerful, it will also be more eco-friendly.

3D printing for architects


3D printing for architects

Initially, 3D printing was not created for architects. In fact, most 3D printer manufacturers probably didn’t even foresee their machines’ potential in architecture.

The printers were mainly designed for the aerospace and automotive industries, or other sectors requiring physical realization of elements in order to test their design.

Things have changed, and 3D CAD applications are now very much a part of the design process. 3D printing has become a strategic necessity for architects.

The question is no longer “should we go into this?” but rather “how are we going to integrate 3D printing into our business?”

Architects can use 3D printed models in the same way as hand-made ones. But they have the added benefit of being faster to design, less costly and more accurate.

Many architects recognize the ease of use of 3D modeling software such as Google SketchUp, which is particularly useful in the early stages of design, when multiple iterations of a model are required.

The problem is that SketchUp, like many other 3D CAD applications, is more of a rendering tool than a solid modeling system. Designers must therefore be especially careful when preparing their model for 3D printing to ensure a flawless print. To be honest, it should be noted that Google’s v8 of SketchUp has resulted in marked improvements in addressing the needs of solid modeling.

Below is an example that illustrates how 3D printing has become essential for any architecture firm.

On its blog, 3D printer manufacturer Zcorporation quotes from a recent article in Building Design.

We learn that British Education Secretary Michael Gove called Amanda Levet “Britain’s best architect” at the Globe Academy’s opening ceremony.

Said Gove: “So much care and attention and the work of Britain’s best architect has gone into providing you with the best possible building in which to spend the next few years.” He said everyone involved in the design had “shaped a building which is impressive on the outside and beautiful on the inside”.
