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.

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.”

Fender chose SolidWorks CAD software – first deployed on the JACKSON and FENDER STRATOCASTER lines and now used companywide – because it is easy to use, includes advanced surfacing capabilities, and integrates well with CAM applications. By deploying SolidWorks, Fender cut production time by 20% across the board, reduced the time required to shape guitar necks by 30%, eliminated many secondary operations, and increased production throughput with improved tooling.

“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.

The company’s product line includes escalators, moving sidewalks, passenger elevators, sightseeing elevators, and freight elevators. These are produced on some of the most advanced manufacturing equipment in China, including a Salvagnini fully automatic flexible sheet metal production line. Major projects in China include the National Centre for the Performing Arts, Capital Airport and the National Stadium (the Bird’s Nest).

Elevators are electromechanical systems that must fit perfectly into the customer’s building; they are shipped as bulk components and installed at the customer’s site. Thus, most projects are one-off. Management set a goal of standardizing portions of the design process as a way of boosting productivity.

Another factor that previously hampered productivity was the use of multiple CAD programs that could not communicate with each other. “Giant KONE boasts a large number of designers of different ages and different levels of expertise, and their design software varied widely,” says Li Yong of the company’s Information Management department. “Problems were often encountered in upstream and downstream communications and as drawings were modified.” The company also lacked a comprehensive digital solution for managing its operations and product data.

Giant KONE’s original CAD software was 2D, which was adequate when the company had fewer orders, but as the workload grew, the drawbacks became evident. “Sometimes, a design had to be started again from scratch, just to make a simple 5-millimeter change in the dimension of a part,” says Yong. When designing new parts, designers made physical models first, then made drawings based on the models, made a round of physical prototypes from the drawings, and then verified the prototypes.

The chance to make a significant change to the design process came during a project done in conjunction with the National High Technology Research and Development Program 863. Called “Study of the Configuration Management Technology of Large Batch Customized Products and Its Application in the Elevator Industry,” this project was Giant KONE’s impetus to upgrade the design process from 2D to 3D. After investigating and testing a number of 3D solutions, Giant KONE chose Solid Edge software with synchronous technology from Siemens PLM Software. It hired United Digital Systems, Co. (UDS), a Siemens PLM Software platinum partner, to handle the implementation.

“Since implementing Solid Edge, Giant KONE has witnessed remarkable improvements in efficiency,” says Yong. With more than 90% of all products and components now modeled in 3D, it is possible to simulate the assembly of an elevator in Solid Edge prior to manufacturing. Only 2 physical prototypes are now required, down from 5 or 6 in the past. Engineering drawings are more accurate, and they are quickly created from the solid geometry. The average research and development (R&D) cycle for a new product has dropped from a year to 9 to 11 months.

“In working with a variety of parts, components and assemblies during the R&D of a high-rise escalator, Solid Edge with synchronous technology enabled our designers to easily locate problem areas and quickly modify them.” says Yong. “Synchronous technology enables our designers to significantly increase their modeling efficiency.” He explains, “In the past, we got all parts and components ready before assembly. Now, using synchronous technology, we work in a top-down way – first concept design, then accurate design and finally standardization.”

According to Yong, Solid Edge saves the company significant money. Solid Edge Simulation enables the company to improve its design verification process. Yong explains, “We’ve essentially eliminated physical prototypes. We now use Solid Edge for virtual assembly, dimensional simulation and interference checking, thus minimizing material waste and substantially reducing costs. Ultimately, using Solid Edge, we’ve saved ¥3 million.”

Yong adds, “The integration of Giant KONE’s Solid Edge design system with other applications has allowed the company to optimize our product design and manufacturing processes. Barriers between departments have been eliminated; information is immediately shared; and what you see is what you get in a design.”

Black Diamond’s goal was to combine the two sets of performance criteria in one great-looking boot. “The other free-ride boots out there are made by European competitors with 50+ years of boot-making experience,” explains David Narajowski, director of advanced projects at Black Diamond. “Our challenge was not just to catch up to where they were, but to go beyond and create something much better.”

Black Diamond is a long-time user of CAD and has used its original design software, I-deas, from Siemens PLM Software, to develop many of its successful products. At the time the boot project started, however, the company had decided to standardize on the NX digital product development system, also from Siemens, an advanced design solution that still allows the company to leverage its legacy I-deas data. “Black Diamond’s design engineering centers worldwide have moved from I-deas and other CAD systems to standardize on NX,” Narajowski says. He notes, “Between I-deas and NX, there was a period of time when we tried a mid-range CAD program. But there is no way we could have developed a free-ride boot in a mid-range system.”

One of NX’s main advantages, according to Narajowski, is that it provides both the freeform modeling capability needed to capture the company’s design expertise (through the NX Shape Studio application, offered as part of the NX Mach III industrial design solution) as well as the powerful product design tools needed to turn an idea into a manufacturable product. “This is a perfect combination for BD’s hands-on, chop-shop-inspired, fail-fast-to-succeed-sooner approach to design,” says Narajowski. “Working with NX Shape Studio, we can directly manipulate surface geometry to do things like capture anatomical nuances of the foot. And this functionality is integrated with NX product design tools such as WAVE that let us go from one original conceptual model to three different product families with 10 sizes each.”

Jake Hall, Black Diamond’s lead industrial designer on the project, explains the need for such tight integration this way: “One of the great challenges of designing ski boots is that there is very little separation between performance and aesthetics. Fit, performance and aesthetics are one and the same. This means that engineering, industrial design, and manufacturability must be tied together seamlessly in order to create a successful product. Any apparent seams between the two disciplines would result in poor design.

“Fully integrated engineering and industrial design means that we needed both surfaces and solids as native parametric features within a model,” Hall continues. “NX, and particularly the powerful surfacing features in Shape Studio, provided the hybrid capabilities of surfaces and solids that the project required.”

The tight integration between the NX conceptual design and product design environments was key to optimizing the performance of the boot, a task that involved a lot of actual skiing and hiking in prototypes. “If someone came back and complained of pressure here or a pinch there, we could grab those surface points in Shape Studio and easily make a change,” Narajowski notes. “But those changes are not made in a vacuum. It’s not like we throw the design over the wall from industrial design (ID) to engineering and hope the design intent isn’t lost. We’re also using NX tools and the same geometry we create in NX Shape Studio to analyze the boot’s performance and to design injection molded parts. That is the real strength of NX for us.”

Engineers at the Black Diamond headquarters in Utah worked with their colleagues at the Black Diamond office in China on the design of the boot. The ability to share the workload in an efficient and accurate manner is another important benefit of NX on a project such as the free-ride boot, according to Narajowski. “NX allowed us to break up the model and have more than one person working on it at a time,” he explains. “There would be an ID person working on outside surfaces, for example, while someone else was working on the foot shape or on the cutter for the buckles. People could work on their own parts, and then we could pull them in and automatically update the ‘super part.’

Nearly all of the free-ride boot project was done using Siemens software. The integrated nature of the NX solution made it possible for the design team to go through the many iterations they needed to catch up to and surpass the competition. “Without having all that existing experience, we had to try a lot of iterations. We wouldn’t have been able to go through the iterations fast enough without tools like NX,” Narajowski adds.

The boot has been previewed to the industry, to rave reviews, and sales will begin in time for the next ski season. “As the largest, most expensive, complex development project we’ve ever undertaken, it’s hard to contain my enthusiasm about these boots,” says Peter Metcalf, CEO of Black Diamond. “They represent the best of BD today, exemplifying our design philosophy in terms of innovative product. BD boots will fully meet the demands of today’s free-ride skier. We set out to build a better boot for the skier who wants one boot to rip all terrain and our design team has delivered.”

Dassault Systèmes worked with Mougin and his team to simulate the iceberg’s trajectory and its evolution by taking into account data such as variations in ocean temperatures, wind force and direction, sea currents, and boat drag force. They inserted this data into a 3D model of the iceberg to simulate what would happen all along the voyage.

The critical challenge presented to Dassault Systèmes’ engineers was to demonstrate, using virtual technology, the technical feasibility of displacing the iceberg in a controlled manner while reducing its melting. The project, managed by Cédric Simard, Interactive Strategy & Marketing Project Director at Dassault Systèmes, involved a number of steps:

1. Model the iceberg with CATIA based on a cloud of points obtained by scanning a real iceberg with radar.
2. Calculate and simulate the way the iceberg would melt using CATIA Systems and SIMULIA.
3. Simulate the way the iceberg would melt if surrounded by a protective isothermal “skirt” imagined by Mougin to slow the melting process.
4. Calculate how much fuel the boats would consume depending on the winds and currents encountered along the way

Various scenarios were simulated, such as number of boats needed, different departure dates and climate conditions, and the behavior of the boats and iceberg in the event of a storm or turbulence. In addition to enabling the team to visualize these scenarios, the simulation also allowed the scientists to test how to deploy the isothermal skirt around the iceberg.

The product development team at PTC came up with the idea of a creating single program that does everything versus offering diverse programs with no connectedness. The strategy addresses its customer base and the trend toward solid modeling for the masses. Creo 1.0 is the result of that concept. The software currently has nine applications including Creo Parametric, Direct, Illustrate, Schematics, View MCAD, View ECAD, Sketch, and Layout.

The company focused on a group of traditional user problems and applied a core of technologies against them, specific roles having options for modeling modes with the click of an app. Simplifying a process that has plagued engineers and designers for decades makes using the software and being productive all the difference. The Creo GUI is much cleaner than the Pro/E GUI. According to those who have used the new product, the GUI strategy is most evident in Creo Parametric and Creo Direct. PTC leveraged the best features from CoCreate and made it easier to use. The company added features to Creo Parametric that will make Pro/E seem like ancient technology. Creo proves that a feature can live in a history-based and history-free environment keeping the parametric relation to features within each if needed.

Another 2011 debut was SolidWorks 2012 that also sports new features to help a more diverse audience. The software has improvements in assembly and drawing capabilities, built-in simulation, design costing, routing, image and animation creation, and product data management. Dassault Systemes says SolidWorks 2012 will help automate design functions, change product development processes, and extend support for collaboration and connectivity. This technology could change how the software is marketed and sold. The product helps users streamline design processes by removing traditional steps.

Autodesk’s AutoCAD 2012 and Design Suite 2012 series are available in a range of offerings including web and mobile applications. Thus more users have access to the technology and can stay connected to their work no matter where they are.  In addition, AutoCAD 2012 and Design Suite 201212 are directly connected to the free AutoCAD WS web and mobility application.

With CAD pretty much saturating the engineering and manufacturing arena, CAD vendors are realizing that pumping out a redressed version of what went out the door at the last launch is not going to work much longer. They have to offer tools that appeal to other audiences. We have seen that starting to happen in the retail, hobby, and jewelry industries where non-engineering types are using 3D programs to crank out new products.

Moving its designers onto a standard platform worldwide meant integrating the Autodesk manufacturing technology with other key enterprise systems. As a result, Voith has synchronized its design teams and achieved new heights in speed and efficiency levels. “By integrating our 3D models into our SAP ERP system, we can make design changes more quickly. Every engineer has access to the same information, said Voith’s Olaf Spitzer. “This allows us to respond to our customers’ needs faster.”

Frederich Spitzer, PDM Support Manager, IT Solutions for Voith, “We are organized into centers of competencies, so every location with manufacturing capabilities has competencies for a certain product in the finished machine. By installing a common Inventor SAP ERP system with help from Autodesk Consulting, we bring all the information that is generated by these different locations together in one system.”

Voith is also gaining efficiencies associated with the enterprise parts management system built by Cadenas GmbH. The PART system reduces design time by providing access to components and assemblies. Design and development engineers are able to see relevant part information such as price, delivery time, and release status in one user interface.

With a common database, Voith’s design team now uses the same items with the same information. By streamlining parts numbers, Voith facilitates procurement, inventory, and maintenance.

Today, Voith is creating more accurate designs faster. Each machine is designed by several of Voith’s centers of competencies and then assembled at the customer site. Since adopting Inventor, Voith has reduced assembly problems.

“By integrating Inventor with our ERP system, we can respond quicker to our customer needs,” said Olaf Spitzer. “We are able to show them designs before we build a machine. For one project in China, a company ordered parts of a paper machine. We showed them the design and they had changes which we were able to make overnight. We then presented the new design to the customer the next day and secured an order.”
