PTC has been working on mobile apps for some time now, and is set to deliver its first generation with the 10.1 release of Windchill, in March.

In a phone call today, David Blair, VP of Product Management for PTC, provided some background on PTC’s mobile plans.

The company is delivering first on the iOS platform (iPAD and iPhone), with Android to follow.

Initial use cases will include:

• Search for products, part numbers, and documents
• Viewing of metadata, including attributes and lifecycle state
• 3D viewing of parts and assemblies
• Viewing of workflow tasks

Here are a couple of screen shots, as a preview:

There is more to come. These are some of the apps in development at PTC, and headed for the market this spring:

Mobile PLM for the engineer: Being able to log a problem report on a mobile device from the factory floor or in the field. Having access to your access PLM information on iPhone and iPad, such as accessing and approving tasks assigned to you, searching your development database, viewing product info such as meta data, and visualizing objects through a 3D viewer.

Mobile PLM for the administrator: Being able to check the server, and quickly see how everything is running without having to go into the office to fix any issues. In addition, the administrator can provide support for advanced modules, such as project data, advanced reports, or manufacturing process plans – again, without having to be in the office.

Mobile PLM for the service technician: Being able to access, update and implement relevant technical service information from the field to keep crews working.

Mobile Social Product Development: Being able to access all of your social product development communities from your mobile phone. Watch the team feed, see what people are talking about, how they are solving issues while you are in the waiting room at your doctor’s office.

CAD creation mobile sketching tools: Upgrade from back of the napkin drawings. Draw directly on your iPad and have the data automatically be stored in the PDS – or shared your social community.

3D CAD Tips

The cost can be daunting. But what if there was a way to spread it out, and pay as you go?

Rental: An idea that’s been tried.

A dozen years or so ago, a relatively new CAD vendor, Think3, started offering their CAD software on a monthly rental basis. It was an intriguing idea, but it would have worked better had Think3′s software been more mature at the time. People tend not to renew rentals when the software doesn’t do what they need.

More recently, Ashlar-Vellum has offered their line of CAD programs under a number of licenses, including permanent, one-year, and monthly rental. Though Ashlar’s software is highly respected (especially by industrial designers), the company isn’t one of the big players in the CAD business.

Recently, Siemens PLM, which is one of the big players, revisited the idea of renting CAD software—but with a new twist. They partnered with Local Motors, a company that does crowd-sourced design of cars. Members of the Local Motors community can rent (actually “subscribe,” but with enough flexibility that it seems like renting) a special version of Solid Edge called Design 1, for $19.95 per month.

Solid Edge Design 1 is a capable CAD program, incorporating Siemens’ Synchronous Technology direct modeling tools. It’s no toy.

There are a couple of key things that make this initiative interesting. First, Solid Edge Design 1 is capable of effectively importing and editing solid models imported from most common CAD systems, including SolidWorks and Pro/E. Second, Design 1 is a direct modeler (it doesn’t include history-based modeling), so it’s quite a bit easier for a normal person (as opposed to a CAD guru) to get up and running on than systems such as SolidWorks and Pro/E (or, for that matter, the full-blown version of Solid Edge.)

Simplicity can be compelling: Solid Edge Design 1 can work with the data you have, doesn’t take a whole lot of time to learn to use, and only costs 20 bucks a month, with no long-term commitment.

One good question might be why Siemens PLM is offering Design 1 through Local Motors, instead of directly. It’s probably because Jay Rogers, Local Motors’ CEO, came to Siemens PLM, and said “this is what we’re looking for.” Siemens PLM responded, saying “that sounds interesting. Let’s give it a try.”

The only real “catch” with Solid Edge Design 1 is that it’s really only intended to be used for Local Motors related projects. Its native CAD files can not be read by the commercial versions of Solid Edge (though, because it is a direct modeler, it can write perfectly good neutral files, such as IGES, STEP, and JT.)

Siemens PLM has recently gone beyond just offering a $20 per month version of Solid Edge to the Local Motors community. They’re now offering the full-range of Solid Edge versions, up to Solid Edge Premium, with full FEA simulation, wire harness design, pipe and tube routing, for rental prices ranging from $99.00 to $299.00 per month. These versions of the software can technical support from Siemens.

At first blush, $300 a month sounds like a lot of money. It might be, for a hobbyist who just wants some CAD software to play at designing cars. But, for a person who plans to use the tool for serious work, it’s not that much. Put it in context: A commercial license of Solid Edge Premium sells for on the order of $7,500 up-front, plus another $2,000 or so in annual maintenance fees.

To me, $300 per month for this software, including updates and direct support, seems like a bargain.

For small to medium size businesses, the ability to pay for software as an expense, rather than as a capital item, is pretty compelling. Even more compelling is the ability to control costs by adding or reducing CAD seats as needed.

Is software rental the wave of the future?

Software rental has three problems that CAD vendors don’t like: First, the revenue stream has to be recognized for accounting purposes as it comes in, rather than upfront. For publicly held corporations focused on reporting lots of revenue, that’s not very attractive. Second, it’s hard to pay front-loaded commissions and bonuses to salespeople on rentals. And third, there’s no guarantee that someone who is renting software will continue to do so. That is, it’s difficult to “lock-in” those customers (and their revenue) over the long term.

Siemens PLM could get away with this initiative for a few reasons: They limited it to Local Motors community members, so they can learn what works (and what doesn’t) without messing with their entire customer base. As Solid Edge is not the market sales leader, they’re more likely to displace competitive seats than their own. Since the Solid Edge product group is only a tiny part of the giant Siemens corporation, there’s not much risk that this program’s success or failure will impact their next quarter’s financial results (and stock price.) And, finally, they have enough confidence in their product to believe that a pretty reasonable percentage of the people who have a chance to use it will like it.

While the Siemens PLM/Local Motors partnership is probably a bit of an experiment, it’s encouraging. Anything that can make good CAD tools more affordable is likely to be popular with users.

The software is an application-specific extension to the Opera electromagnetic simulation package. It provides a front-end to the simulator that speeds design entry by means of Wizard-style dialog boxes. Users select the style of motor or generator they want to design from a library of all common types, including induction, brushless permanent magnet and switched reluctance motors, and synchronous motors or generators. Then, dialog boxes allow you to enter parameters to define mechanical geometry, material properties and electrical data, and the FEA model is automatically created.

The use of parameterized models and the ability to load and modify previous designs have made it possible for users to perform ‘what-if?’ design investigations. Cobham has integrated a unique optimization tool that makes it simple for users to find the best solution across the design space. While auto-optimization tools are not new, they usually require manual intervention if the globally optimal solution is to be found, and the simulation times involved often make this impractical. The Optimizer selects and manages multiple goal-seeking algorithms including stochastic, descent, particle swarm, and Kriging to eliminate the need for manual intervention.

Setting up an Optimizer run from the Machines Environment is easier. Because most FEA simulations can take as little as a few seconds, the integrated software makes it possible to thoroughly explore the design space. Thousands of simulations can typically be executed within hours, making the perfect solution achievable for all users – without expert assistance.

 The 2D Machines Environment has an extensive library of rotating machine design styles and design components. However, if there are still any unusual features that need to be incorporated in designs, users also have open access to the scripts that generate the models, and can modify them at will to automate proprietary motor and generator design concepts. A library of common material properties is also included in the design software. Again, if users employ any special materials, such as an unusual grade of steel for laminations, then a new menu item can be created. Cobham will also generate custom scripts for users on request. A 3D version of the Machines Environment is available.

3D CAD Tips

The term “expensive graphics card” might be troubling to GPU suppliers such as Nvidia and AMD. Yet, it is probably more accurate than, for example, “high-performance graphics card.” For many years, all graphics subsystems used in CAD capable computers (whether built-in, or on an add-in card) have been relatively high-performance. When comparing entry-level with top-of-the-line graphics, the most stark difference is price: free (something that comes with the computer), versus not-free (something you need to pay extra for.)

It’s only after you’ve come to the conclusion that it’s worth paying that extra that you need to start digging into the question: How much extra?

The practical differences between $100 graphics cards and $2000 graphics cards are not all that obvious to the uninitiated. There is no simple number-of-merit on a specification sheet that will tell you how good a graphics card is. To choose well, you need to start by doing a little homework.

A good starting point is AMD’s ebook, Simplifying the World of Professional Graphics. It’s well worth the read, even if you’re already reasonably knowledgeable about graphics hardware.

All seriousness aside, SpaceClaim does have compelling sheet metal tools for people other than pretend pirates. And, unlike some older CAD programs, SpaceClaim is relatively fun to use – probably because it doesn’t make you “walk the plank” to get your job done.

What this video alludes to, without coming right out and saying it, is that SpaceClaim, as a direct modeling CAD system, lets you use whatever existing part geometry you may have, from just about any other CAD system, as a starting point for sheet metal design. So, if someone throws a part file at you, and asks you to turn it into sheet metal, you can get it done with minimum fuss – even if the original CAD file is a mess (as many are.)

In the last few years, SpaceClaim has been starting to make an increasingly large impact on the market, not just because it works well, but also because it doesn’t require users (or the companies they work for) to throw-out their existing CAD tools.

After this video was posted, Blake Courter, a SpaceClaim co-founder, commented on Twitter that this year’s marketing campaign for SpaceClaim “consists entirely of setting up booths at renaissance festivals.” I think he was kidding (though I wouldn’t be surprised to see SpaceClaim at Burning Man later this year.) Until then, you might try visiting their website.

3D CAD Tips

Electric bikes use less than 1,000 watts of total power and can be used on bike paths. When Hays first encountered these hybrid vehicles, most models were imported from a variety of countries. They relied on an injection molding manufacturing process which produced parts made of a variety of thermoplastics. While initially pleasing in appearance, the plastic parts raised questions of reliability and tended toward unsightly discolorations and dangerous cracks. “As an advocate for electric bikes,” said Hays, “I felt these problems had to be solved.”

To efficiently produce a more reliable and environmentally friendly electric bike, Hays’ company Pi Mobility took a minimalist approach. For Hays and his team, the longer a product will last is a key factor in making it more sustainable. Rather than rely on brittle plastics for a multitude of parts, Pi Mobility used an elegant, solitary arch of recycled aluminum for its bikes’ iconic frame. The recycled aluminum lasts longer than plastic and the batteries and electronic components reside safely within the aluminum tube rather than an injection molded plastic battery enclosure.

Recycled aluminum requires one-thirteenth the amount of electricity to produce compared to virgin aluminum. And, a Pi Mobility bikes produces 300 lbs of carbon dioxide per 12,000 miles of travel, making it 20-30 times more efficient than a motorcycle or cart. The single tube used in the PiCycle and PiMoto models’ battery agnostic design means they can conceivably handle any battery or chemical process that produces electricity, allowing for easy upgrades in the future.

Thanks to the less labor-intensive design of the single tube, Pi Mobility has been able to maintain production in the US and still be profitable. “We can form a tube in about 30 seconds,” said Hays. “With the help of Autodesk software, changes to the design can be embedded very quickly. Our manufacturing method offers very rapid scale at competitive prices, but it also reduces the required labor to a fraction of more traditional electric bikes. By producing our bikes locally, much of the transportation carbon that often affects even environmentally sustainable good can be eliminated.

The company’s testing program makes durability and sustainability its top priorities, before appearance. Pi Mobility seeks to combine all three elements at every opportunity. The Autodesk solution for Digital Prototyping helped the company to optimize its design and bring new products to market faster.

Hays said,” We use Inventor, Vault, Alias Design, and Showcase. Our design team took to the software immediately. After just three weeks the team produced a 3D digital prototype using Inventor. It proved that by increasing the diameter of our tube by a half inch, we could save $335,000.”

Concept2 was founded by Dick and Peter Dreissigacker in 1976. Fresh from Olympic training, the two brothers designed and created the first composite carbon fiber racing oars, and went on to prototype the world’s first wind-resistance indoor rower out of old bicycle parts. The Dreissigacker Racing Oars are now used by more than 70% of the rowing community. The Concept2 Indoor Rower has been redesigned and upgraded four times since the Model A was introduced in 1981. Today’s Model D and the recently introduced Model E both build on Concept2′s 26 years of experience in designing and manufacturing rowing machines.

“KeyCreator is integral to our design and manufacturing process,” said Jon Williams, chief engineer of Concept2. “The software enables us to quickly develop, test and iterate conceptual models. KeyCreator makes it easy to communicate those design ideas accurately to our supply chain partners.”

Responding to both customer feedback and rising manufacturing costs, Concept2 decided to evolve its overall rowing system. One area identified for a major design change was the flywheel enclosure. Now in its fifth generation of indoor rowing machines, Concept2 has moved the flywheel from an original unenclosed bicycle wheel to the current three-piece injection molded housing available in today’s Model D &  Model E. Concept2 engineers took advantage of KeyCreator to design current advancements into the Model D.

“When our customers requested greater battery life in the rowing machine monitor, Concept2 designed an efficient, non-contacting generator that powers the monitor as the machine is being rowed.  And when customers wanted a quieter flywheel mechanism, Concept2 used KeyCreator to experiment with different shape housing designs that delivered significant noise reduction,” added Williams.

Accurate exchange of CAD data is vital to Concept2. The Concept2 Indoor Rower has become the standard across the rowing community in part because of the high degree of comparability between scores achieved on individual rowing machines – ensuring that 2000 meters rowed on one Concept2 machine is exactly 2000 meters on another. This standardization has proven significant during races, such as those at the CRASH-Bs (indoor rowing championships).  The accurate exchange of CAD data between Concept2 and its partners guarantees standardization, regardless of which manufacturing plant or assembly plant is building a rowing machine or producing any part.

Concept2 is dedicated to providing the most innovative rowing products and programs to its customers.  That commitment depends on imagination and advancements in technology developed by the engineers using KeyCreator.

The team originally planned to build the sculpture with glass fiber composite, but fire codes would have required additional engineering studies to prove it was flame retardant. Additionally, the building was going to be largely enclosed by the time the sculpture was ready for installation, making it impossible to bring the sculpture, which is 14-ft wide and more than 16-ft high, into the building in one piece.

Argent had designed the sculpture as a form composed of hundreds of flat triangles. “The piece lent itself to aluminum as long as we could figure out how to fabricate the pieces,” said Bill Kreysler, who founded the fabrication company in 1982. Working with Argent’s digital renderings, Kreysler’s team translated the design into Rhino software, creating what he calls a semi-monocoque structure with a double-skin of thin aluminum on a thin-ribbed interior aluminum frame. The decorative surface is composed of 1,446 CNC-cut triangles with side dimensions ranging from one in. to three ft. Etched with a numbering system, the triangles were placed using laser-projected grid lines.

“I think that one of the things that is often overlooked in this digital fabrication world is that there’s a sense that because computers are controlling the process, the human element is reduced, but in many ways it’s increased,” said Kreysler, who limited the number of people working on the piece to ensure consistency.

The rabbit’s interior structure was assembled into 14 pieces of varying diameters in the shop, then transported to the airport for assembly. The exterior aluminum triangles are textured with crushed glass to create a velvet-matte surface and float 1½ in. above the interior shell with aluminum standoffs.

Even in the light-filled atrium space the sculpture’s suspension system appears minimal. The concentrated loads coming from seven custom wire rope suspension cables with swage fittings are received by the rabbit’s internal steel armature. Aluminum transverse members then distribute these loads from the steel armature to the monocoque aluminum shell.

Unveiled on October 6, 2011, the new $1.3 billion airport addition is the largest construction project in Sacramento’s history. The rabbit is the centerpiece of the 14 art installations—more than $6 million worth—commissioned by the city’s Metropolitan Arts Commission and planned for completion in the coming years.

“In between my freshman and sophomore years, I became irritated at how cumbersome it was to rotate a model using a traditional mouse. I thought I could get a trackball mouse and program it so when I rotate the mouse it rotates the part on screen. That’s when I came across 3Dconnexion. I ordered their SpaceNavigator right away,” said Ellis.

In 2009 during his senior year, Ellis began researching an aerial robot competition. Five days later, he started the Michigan Autonomous Aerial Vehicles (MAAV) team with 15 members. Within one week, the team kicked off their first quadrotor design for the International Aerial Robotics Competition (IARC). At the end of the first year, MAAV successfully built two quadrotor vehicles capable of manual flight.

“The IARC challenge is to build a flying robot of any type you want. We chose a four-rotor helicopter that can fly through an unknown building completely on its own,” added Ellis. “There can be no communication with the device. The robot follows signs, must avoid detection from security cameras, locate a room, retrieve a flash drive, drop off the decoy, and get out in less than 10 minutes. No one has completed the mission yet, but we are one of the better teams competing. It’s the most challenging mission to date.”

When Ellis started the team, he wanted to get a 3Dconnexion 3D mouse for everyone. “It makes modeling CAD designs so much faster and easier,” said Ellis. IN addition, the team quickly realized trying to fly the quadrotor with a standard joystick didn’t mimic the movements very well and wasn’t intuitive enough for the user. A 3D mouse could mimic the exact movement of the robot. It was at this point the team decided to take matters into their own hands and control flight with a 3D mouse.

“We use the 3Dconnexion SDK to develop a driver to control the quadrotor with the SpaceExplorer and it quickly allowed us to control pitch and roll, zoom control height, and rotation control yaw,” noted Ellis. “In addition, The SpaceExplorer’s Intelligent Function Keys control other commands such as on/off and camera control.”

Today, Ellis is still the head of the MAAV team while also completing two masters in aerospace engineering and robotics. He continues to use CATIA for all of his designing both for the team and his class projects. He also works at a student lab training other students involved in competitions in CAD modeling and machining.

He uses the SpacePilot Pro. “A 3D mouse allows me to easily interact with the model while clicking and drawing in 3D at the same time,” he said.
