Model-based definition or the perils of disconnected detours

By Leave a Comment

By Brian Thompson, DVP and GM, CAD Segment, PTC

When I speak with manufacturers, they often tell me that moving towards becoming more model-based is at the top of their priority list. Initially, they might have started down this path to eliminate the extra work required to build 2D drawings off of their 3D models. Now, manufacturers want to make the 3D model itself the gravitational center. The disconnect between the 2D drawing and 3D model is hobbling both their internal efficiency and external competitiveness.

More formally known as model-based definition, MBD is about creating rich “Technical Data Packages (TDP),” which include the 3D model and associated data elements. At the core of the TDPs is the 3D model, along with its associated dimensioning and tolerancing to clearly communicate design intent and geometric form control. Thanks to the TDP, users who sit downstream from engineering can understand and use that model without needing separate 2D artifacts – the information is in the model itself.

MBD is not another way of spelling ‘paperless engineering,’ as if mere convenience were the reason for such a strategic shift. The manufacturers we work with are talking about a broader and grander idea: a different way of approaching the product development, manufacturing, delivery, operations, and service processes so that the 3D model is the source authority.

By implication, these manufacturers are also talking about innovation, and how they might use breakthrough technologies such as simulation, additive manufacturing, and generative design to design better products faster. MBD is as much an approach to corporate strategy as it is an approach to design, product development and manufacturing.

That’s the exciting part – the vision that gets people to commit their time and resources to the effort. I would offer this advice to those who aspire to a model-based journey. Think of a rock climber scaling a cliff face. As he or she ascends, that climber will need to put an anchor in the rock through which to pass the rope.

Your 3D model is that anchor. Start there.

3D model as Anchor
This is no getting around it: every MBD journey starts by looking at your modeling practices and ensuring that your model truly reflects your design. One customer discovered, as they implemented MBD, that they had to train their engineers to know where and how to apply drafts to their injection molded parts, instead of relying on the manufacturing team to do it. Another found that simulation results would be inaccurate unless certain critical features were modeled in complete detail, instead of leaving some geometry details to notes.

Today, I look at the model itself as a precise database for all PMI rather than as a supporting item to create a 2D drawing quickly.

A geometrical product specification is gold for manufacturers.

A word of caution
Next, examine your own mental models and beware of outdated beliefs. We sometimes see those who have (unknowingly) gone halfway with MBD – only to stop on the manufacturing floor. In the past, a certain amount of rework was part of the design process, as was the willingness to accept change at the worst possible and most expensive time. Allow me to be candid. With MBD, your experts on the shop floor will need to learn to place the 3D model at the center of everything they do, too. This will surely help them streamline industrialization of the design, minimize mistakes, and produce the highest-quality output. This will definitely be a change for the manufacturing team, but everyone I’ve talked to has said this is worth it.

Disconnected detours
The worst choices in business are ones you don’t know you’re making. With that in mind, consider whether an MBD journey would, in fact, be less costly in time, money, materials and morale than situations such as the scenario described below.

At one manufacturer, final drawings were made into pdfs and put on a server where all could access them. Not surprisingly, CNC machines soon were decorated with marked-up pdfs showing late-breaking changes. As the model evolved, there was no way other than person-to-person to get the changes to the manufacturing floor. One employee jokingly referred to the ‘sneaker net’. The manufacturing engineers encountered the same situation, and the changes they made on the shop floor often didn’t get to the designers, who unknowingly proliferated errors.

In our opinion, becoming model-based is a journey. To prepare, commit to making the 3D model the source of all authority and then take a moment to reexamine your modeling practices. This will take time, but your reward will be more value for the investment you’ve already made, confidence that engineers can now spend their valuable time doing what you paid them to do, and circumstances more favorable to innovation. That’s what our customers are seeking.

Vuforia Instruct offering streamlines the creation of 3D CAD-based work instructions

By Leave a Comment

From the stage of the Vuforia Live Virtual Event, PTC  announced the release of the new Vuforia Instruct out-of-the-box offering from the Vuforia Enterprise Augmented Reality (AR) Suite.

With PTC’s Vuforia Instruct, enterprises can leverage 3D CAD data to easily create, deliver, and scale interactive AR work instructions

The Software as a Service (SaaS)-based offering, available on the PTC Atlas platform, empowers original equipment manufacturers to extend the value of the digital thread all the way to their front-line workers. With Vuforia Instruct, enterprises can leverage 3D CAD data to easily create, deliver, and scale interactive AR work instructions, enabling them to optimize inspections for Quality and Field Maintenance use cases.

“We are thrilled to be working with PTC and Rockwell Automation to bring AR to our customers, and see tremendous opportunity to use 3D work instructions to address critical inspection steps within our maintenance, repair, and sanitation processes on our packaging equipment,” said Alexander Ouellet, Innovation Engineer, Harpak-ULMA Packaging. “The enhanced work instructions created with Vuforia Instruct enable us to upskill our customers’ employees, and even our own technical staff, on intricate procedures in mission critical environments. AR technologies will help our customers reap significant productivity gains by enabling them to improve the accuracy and timeliness of complex, manual processes.”

Approximately 67% of manufacturers are still utilizing manual paper processes for inspections. These existing methods are often error-filled, difficult to transcribe, and costly – ultimately becoming barriers to continuous improvement. Such inefficiencies can result in poor product quality or experiences, cost millions of dollars per year, and lead to loss of brand reputation, market position, customer satisfaction, and revenue. Vuforia Instruct enables companies to eliminate reliance on paper forms by delivering contextual visual guidance and references to front-line workers with built-in, real-time inspection feedback to capture critical insights.

“Vuforia Instruct enables organizations to transform the way they create and scale work instructions to their front-line employees,” said Michael Campbell, Executive Vice President and General Manager, Augmented Reality Products, PTC. “Leveraging existing 3D CAD data, organizations can now guide employees to exactly where work needs to be done and provide them with detailed instructions for critical inspection procedures in context. Such enhancements are critical to industrial organizations looking to increase productivity, improve quality, and reduce unplanned downtime.”

Look up in the sky, it’s CAD software

A major CAD vendor is betting the modeling software’s future is in the cloud

By Jean Thilmany, Senior Editor

Onshape set off ripples across the computer-aided design community five years ago when it announced its computer-aided design software would exist completely in the cloud. Last fall, PTC acquired Onshape.

The purchase signals PTC’s conviction that engineering companies are ready to embrace CAD in the cloud. The SaaS model, while nascent in the CAD and PLM market, is rapidly becoming the industry’s best practice across most other software domains, said Jim Heppelman, PTC president and chief executive officer.

By bringing Onshape in-house, the software maker has placed itself ahead of the pack in what the engineering software maker sees as the inevitable industry transition to SaaS, Heppelmann said.

“Today, we see small and medium-sized CAD customers in the high-growth part of the CAD market shifting their interest toward SaaS delivery models, and we expect interest from larger customers to grow over time,” he said.

In the future, CAD sellers may reach unique arrangements with resellers to bring CAD in the cloud to a wider user base, according to one potential reseller.

But PTC isn’t going all-in with the cloud. It will continue to offer its on-premise CAD software, Creo.

With CAD in the cloud, designs reside on the software provider’s secure server —rather than on individual workstations. Because the software is accessed and managed online, engineers and designers can work on their models from any location and on any device. The SaaS refers to a provider’s capability to deliver everything needed to run CAD in the cloud—including the cloud infrastructure and the CAD software itself.

Though other CAD makers do offer some type of cloud capability, it’s generally the capability to check files into and out of an application on a cloud-based server; engineers don’t design directly with cloud-based software on other applications, said Jon Hirschtick, president of SaaS, PTC. Onshape differs in that its software exists fully in the cloud and can be used by multiple users in real-time, he added. (Hirschtick founded SolidWorks in 1993 and then went on to co-found Onshape with another former SolidWorks chief executive officer, John McEleny.)

The everyday cloud
You’re already using cloud technology. That’s almost certain. If you have an email account ending in gmail.com or yahoo.com, if you’ve checked a social media account from your desktop or mobile device, if you’ve streamed a movie via Netflix or Amazon or any other provider, you’re a cloud user. The email, social media, and streaming software exist on the software owner’s server (let’s say Google), as does your little piece of it—like your Gmail email address.

Though it’s been possible to run CAD as a SaaS for the past few years, CAD has always been slower than other large, graphic-intense and complex applications to pivot to new platforms, says Len Williams, content manager at designairspace, which gives engineering companies the capability to run any CAD system in the cloud.

“Last year’s acquisition is a very clear statement that vendors like PTC see cloud as a platform of the future for CAD and for all their other software,” Williams added, calling the acquisition a “Windows-level” move.

“CAD systems were originally based on UNIX running on silicon graphics workstations. Then Windows came along and people were laughing at the thought of using CAD on Windows,” he says. “Now most of the major CAD systems run only on Windows.”

Likewise, the way companies buy their CAD software has evolved, he said.

“We went from the old perpetual model, where you buy the software for a workstation, to today’s subscription-based model, where you rent the software,” Williams said. “The next step is when a CAD vendor is running it for you so don’t have to buy hardware or worry about upgrades.”

Large companies already run CAD in the cloud because of the benefits the delivery method offers, Williams added. The difference is, those companies—the French automotive manufacturer PSA Peugeot Citroen is one example—have the funds to build their own, private clouds. Designers, engineers, and suppliers at those companies can access CAD on the private cloud whatever their location: Tulle, France; Brussels, Detroit, or elsewhere.

Working remotely and sharing with suppliers
For the smaller guys, the cloud can bring the same benefits their larger counterparts already enjoy; mainly real-time working together and version management, Hirschtick said.

“Versioning” is built-in, which means file changes are tracked in a central database in real-time. Because any engineer with permission can access the software from any device with internet connection, engineers in different places can work together on a design, such as a power supply, for example. There’s only one power supply file; Onshape doesn’t copy it. But with cloud, everyone in the world accesses real-time single source of truth database. We’re not passing around copies all over the place, he added.

“If multiple engineers happen to be working on that file at the same time, it’s not a problem. If one engineer rounded a corner and another one drilled a hole, both changes get captured,” Hirschtick said. “If we’re both rounding a corner at the same time, you would see my hand there in real-time—at the same table—and a box around the corner would indicate that another engineer is editing that right now.”

The bigger the team is, the quicker the product development process, as everyone—even suppliers—has visibility into the real-time database rather than a copy of something emailed a week ago.

When the workflows are quicker, engineers have more design time and are more willing to innovate to try new things, he added.

Most cloud service providers automatically update their programs. Thus, IT staff can focus on other tasks and engineers know they are working with the latest version of the applications.

Also, engineers aren’t bound to their workstations. The software exists at one central server while engineers work from many. They can be globally dispersed and can work from home or other locations outside the office.

Smaller companies that scale their workforce and supplier base up and down as projects change also stand to benefit from SaaS CAD software. When suppliers move away from a project, the company can easily suspend their CAD license and use of the CAD system, Williams said.

When the coronavirus began making headlines in early 2020, engineering companies running one Onshape customer with offices in three major Chinese cities particularly welcomed the remote-work capability, Hirschtick said.

“Using Onshape analytics, they showed us where people were working before the virus situation in China,” Hirschtick said. As expected, employees worked at the offices in the three major cities.

“Then they showed a map of activity of first two weeks of virus quarantines and lockdowns in China,” he added. “This time there were 20 little circles in regions all over in China. They could see where their employees logged in remotely.

“It doesn’t matter if employees are caught at home with only an Android tablet, they can still do their work,” Hirschtick said. “Even with the phone they can even do some of their work.

There are cases where running CAD in the cloud just doesn’t make sense. Some companies may use CAD only a small amount of time and will do better essentially renting a CAD program, perhaps through the cloud, Williams said.

With cloud-based systems, issues of total cost of ownership and return on investment are generally murky because companies want to see how cloud applications compare to traditional on-site infrastructure.

“But there are so many intangibles wrapped up in the cloud that it makes it hard to put calculations on it,” said Andrew Sroka, CEO at Fischer International Systems, which helps companies manage identities for on-premise and cloud-based applications. “It’s important to factor in expenses like utility costs and power requirements.”

If you can’t buy, rent
With CAD in the cloud being not if, but when, designairspace has new ways to bring benefit to users and CAD makers; reselling vendor software in the cloud. The company would offer customers workstations with major CAD vendor’s programs already installed. Designairspace can track use, which allows the vendors to charge based on time spent using the programs.

“It would be just like mobile phone plans back in the day, where you buy a plan based on minutes. We can do this with CAD in the cloud,” Williams says. “Let’s say you buy a plan with 500 minutes. If you need it for only one or two days a week, you can buy it in a small, affordable plan that’s a small portion of what it would cost you to buy the software.

“Why limit CAD-in-the-cloud to large companies? In the olden days, only big companies could afford 3-D CAD systems. We want small companies to have cloud benefits,” he added. “They would still need to buy their own licenses, but at least they can run it in the cloud, like the big guys.”

The pricing model would benefit companies with project managers or suppliers who don’t design in CAD but log onto the program intermittently.

“These people use the software only a little bit at a time, so we can price it so it’s not so expensive for them,” Williams said. “This is a whole new market for major vendors.”

Becoming a CAD-in-the-cloud reseller and offering online training in those CAD programs is the “next step” for designairspace, he added. With the business model, potential customers can also receive on-the-spot, specialized training if needed and can test the software to see if it’s right for their needs before buying a priced plan, he said.

Or, engineering companies might choose to run hybrid CAD, in which they host some CAD systems at workstations on-premise and buy CAD in the cloud subscriptions for intermittent users, Williams said.

“That way you can gradually move more and more users to the cloud. You can move one or two and see if it works and if it does move more to the cloud,” Williams said. “The heavy users will never move to the cloud.”

That brings up another point. Workstations that run CAD will always be with us, he added.
Companies that do work for the defense department or for the military must do their engineering work on company workstations. They cannot work remotely, Williams said.
For his part, Hirschtick is dreaming big. He expects widespread cloud adoption for CAD as users begin to see the advantages.

“People think cloud tools don’t have the power or speed but that’s an old fable. Cloud tools have more advantage and speed, it’s not a fair fight,” he said. “With desktop tools, you have one CPU sitting on the desktop. With the cloud, we’re able to use unlimited amounts of CPUs. I gave a demo and opened up ten models with thousands of thousands of parts on Macbook in Chrome on a web browser. There’s no CAD workstation that could open them that fast, even the best desktop configuration.

“In a few years, people will be saying ‘how did you ever do CAD on a desktop. How was it fast enough?’” Hirschtick says.

While the future remains cloudy, PTC is backing clearing skies for CAD in the cloud. With a large CAD maker backing SaaS, expect to see a flurry of news and updates. In other words, don’t delete your desktop program.

PTC adds AI and generative design to its CAD portfolio with acquisition of Frustum

By Leave a Comment

PTC announced that it has acquired Frustum Inc., an advanced generative design software company, for approximately $70 million. Frustum’s technology for generative design leverages artificial intelligence (AI) to generate design options. PTC says it is a transformative addition to the PTC Creo portfolio.

Based in Boulder, Colorado, Frustum offers patented desktop and cloud-based engineering software that enables designers and engineers to go beyond the limits of their personal experience by leveraging powerful AI capabilities that guide the discovery of high-performance, next-generation product designs.

“PTC is pushing the boundaries of innovation with this acquisition,” said Jim Heppelmann, president and CEO, PTC. “Creo is core to PTC’s overall strategy, and the embedded capabilities from ANSYS and, later, Frustum will elevate Creo to a leading position in the world of design and simulation. With breakthrough new technologies such as AR/VR, high-performance computing, IoT, AI, and additive manufacturing entering the picture, the CAD industry is going through a renaissance period, and PTC is committed to leading the way.”

Frustum complements PTC’s strategic relationship with ANSYS, which was announced at LiveWorx in June 2018, and will bring analysis upstream to the very start of the design process. With embedded Frustum and ANSYS capabilities, Creo will be able to recommend design approaches using generative design, guide the user through the iterative design process using ANSYS Discovery Live, and ultimately validate the full product design at scale using the broader ANSYS Discovery suite. With these capabilities embedded in Creo, engineers will have unmatched capabilities to rapidly drive product innovation.

“This acquisition is a natural step for PTC and its customers,” said Jeff Hojlo, program director, product innovation, IDC. “AI and machine learning (ML) are widely discussed as two of the most impactful technologies of the future. For design, engineering, and R&D, the potential positive impacts of complementing the development process with AI and ML are astounding: lowering cost of quality (which is currently 20-25 percent of annual revenue at the average manufacturer), improving product success rate (which remains very low with more than 80 percent of products failing), and improving time to market and time to revenue by meeting customer needs accurately the first time.”

The Self-taught design system

By Leave a Comment

Just where will artificial intelligence fit in with CAD software? Here’s a look at where developments stand now, and a preview of what might be coming.

Jean Thilmany, Contributing Editor

Artificial intelligence has a place in the future of computer-aided design technology, but right now, the role AI will play isn’t clear. That’s the view of Jon Hirschtick, chief executive officer of Onshape, which makes cloud-based CAD software. While some CAD makers are delving into AI functionality, the marriage of AI and design software is in the early stages, he says.

“AI has great potential, but so far no one has illustrated how it will unfold,”

Hirschtick says in reference to CAD vendors. “I’m not saying developers are not working on ideas.”

CAD makers would be wise to consider how AI may fit into their software’s growth and expansion. AI should be a $16 billion industry by 2022, according to a projection from research firm Markets and Markets.

AI across industries

First, definitions are in order. Many terms have been bandied about of late, particularly in reference to Industry 4.0, which goes by a number of names, including smart factory and connected factory. Technologies like artificial intelligence, machine learning, big data, Internet of things (IOT), and deep learning will come together to help realize Industry 4.0.

Nvidia installed its Drive PX 2 AI supercomputing platform into a signature- green, self-driving racecar that will compete in the Roborace Champsionship, a global autonomous motorsports competition. Image credit Nvidia.

All these technologies are related in that they build upon each other, says Will Ramsey, director of marketing at Nvidia, which designs graphics processing units. The company developed GPU-based deep learning, which uses artificial intelligence to approach problems like cancer detection, weather prediction, and self-driving vehicles. Here’s how Ramsey defines pertinent terms:

“AI is a broad field focused on using computers to do things that require human-level intelligence. It’s been around since the1950s but was little used because it was limited in practical applications.”

“Machine learning enables AI by providing the algorithms that make the machines smarter and thus give AI a way to actually become more intelligent as time goes on.”

Machine learning is what Ramsey calls an approach to AI, meaning a way to use AI for practical applications. The approach uses statistical techniques to construct a model from observed data. It relies on inputs, or what Ramsey calls “extractors” set by the humans programming these machines.

“It’s like the bag-of-word analysis that made spam filters possible,” Ramsey says.

The filters could search for certain words (determined by humans) within messages, then flag those messages as unwanted spam.

Machine learning algorithms can sift through and find insights in large data sets. Combine AI and machine learning and the algorithms become more able to recognize patterns and specific issues, such as—when it comes to something like speech recognition software—accents.

But where does the data used by machine-learning algorithms come from?

Earlier this year, Nvidia revealed a self-driving car powered by its new AI supercomputer, Xavier, which learns to drive by observing a human driver. Nvidia installed the AI in an autonomous Lincoln vehicle to demonstrate its capabilities. Nvidia Drive PX is an open, artificial intelligence-driven, computing system that can be used as the technology platform for automated and autonomous vehicles. Nvidia developed its own self-driving vehicle to showcase the system.

“Now with social media, sensors, the internet of things, we have all these data,” Ramsey says. “And we have the challenge of understanding and extracting insights from it.”

His company uses what it calls deep learning, a method that automatically extracts and makes sense of all that information, and continues to learn from it or “learns to think.”

“Using deep learning, the fastest growing segment of AI, computers are now able to learn and recognize patterns from data that were considered too complex for expert written software,” Ramsey says.

What about design?

Hirschtick believes CAD programs will make use of AI, but in a more limited way in the near future, by using information the designer has entered to offer suggestions about design parameters and inputs.

Future programs might offer to the design default values for a shape based on the objects that person has designed in the past. AI would essentially learn what types of products the designer mostly works on and the inputs he or she has regularly used for those products. The suggested values may appear on the user’s screen in a dialog box, Hirschtick says.

“Or AI could offer something like: ‘Gee, I noticed you’ve done pattern of activity several times in a row, do you want that or was that a mistake?’”

And AI could make engineers’ search for needed and necessary parts easier. Hirschtick envisions a program, much like that which appears for Amazon shoppers, in which engineers could type in information about a part they’re searching for “and the program says ‘a lot of times people looking for that part also look at this one,’” he says.

Today’s wind turbines, like this one installed in Traverse City, Mich., can be outfitted with a myriad of sensors and actuators that will return real-time turbine operating information through the Internet of Things. Image credit: bengarrison

In the future, CAD software users may also ask speech technology software, rather than the CAD-company’s tech-support operators, questions about the software and instantly receive a pertinent, helpful response. The natural-language-processing programs that drive these responses learn how best to answer user questions thanks to machine learning technology.

Such speech technology software could aid fast-growing CAD companies that would otherwise need to train a slew of customer-support employees quickly.

Currently, those AI possibilities remain unrealized, says Hirschtick. “Right now no one has demonstrated any particularly compelling idea with AI.”

Making manufacturing inroads

Other CAD vendors may beg to disagree.

Autodesk is already moving to use AI for customer support, teaming with IBM to create Otto, a digital concierge that uses IBM Watson technology to manage customer and partner inquiries, says Gregg Spratto, vice president of operations at Autodesk. “Watson’s natural-language-processing and deep-learning technologies help Otto understand the intent of customer questions.”

To offer Otto initial “training,” as it were, the Autodesk team fed historical data from chat logs, use cases, and forum posts into the program to ensure it could understand and respond to a wide range of customer queries.

Then, as the project expands, Otto will use machine learning to handle increasingly complex customer requests and will scale up as call-volume grows.

Also, last October, Autodesk announced plans to embed an AI modeling engine into its IoT cloud platform, Fusion Connect. The Eureqa engine is from Nutonian, recently acquired by DataRobot.

With the AI engine on board, the IoT platform will be able to predict product failures or design flaws based on how a product or device is presently functioning in the real world, says Bryan Kester, director of IoT at Autodesk

The pairing is natural, as IoT offers continual feedback on how products are performing in the field, in real time. IoT makes use of sensors and actuators attached to a product that send back continuous information on how the product is operating, moment-by-moment, in the field.

Fusion Connect helps gather information from that network of sensors and actuators as well as upon RFID, Wi-Fi, and a range of other communications and monitoring technologies, Kester says.

The information is then analyzed and output in a format useful to engineers, who can use it to find where improvements can be made to existing product designs and to determine how new products could be designed better designed. All this based on present, real-world operation, he adds.

Similarly, PTC plans this year to link its Creo computer-aided design system, to the company’s ThingWorx IoT development platform. Developers use the platform to build and deploy enterprise-level IoT applications, says Paul Sagar, vice president of product management at PTC.

Though it’s not an AI application, after the ThingWorx and Creo interface is complete, engineers will be able to instrument their CAD model with virtual sensors that act in the same manner as the real-world counterparts do; that is, they monitor and report back about particular features of part or system operation.

These virtual sensors can offer more insight into model behavior than the what-if questioning and virtual experimentation engineers now use to explore model performance, Sagar says. The sensors can help answer questions like: is the virtual system running hot in a certain area? Is airflow too high or too low?

With those questions answered, designers can redesign and repeat the process until they’ve optimized the model to meet—perhaps even exceed–specifications, Sagar continues.

AI aids 3D lookup

Introduced last summer, Autodesk’s Design Graph is another machine learning system that helps users manage 3D content, offering Google search-like functionality for 3D models, says Mike Haley, who leads the machine intelligence group at Autodesk.

“Machine learning and artificial intelligence are starting to make the first inroads into daily life, but to our knowledge this is its very first application for industrial design and mechanical engineering,” Haley says.

Design Graph algorithms extract large amounts of 3D design data from an engineering company’s designs. It then creates a catalog by categorizing each component and design using a classification and relationship system. Designers and engineers search across all of their files for a part type, such as a bolt or a bike seat, with the tool returning dozens or hundreds of pertinent options.

So how does machine learning come into play?

The system teaches computers to identify and understand designs based on their inherent characteristics–their shape and structure–rather than by tags or metadata, Haley says.

After all, whoever designed the part originally could label it any of dozens of ways, using full words or abbreviations. Metadata created by people, unless carefully managed, tends to be unreliable, Haley says. With Design Graph, the computer uses its own observations about the 3D geometry contained in every 3D model.

So while some AI capabilities already exist within CAD systems, look for more to come. After all, product design plays a key role in the connected factory and the IoT systems of the future. Without design, there’d be no need for a factory—no matter how connected–to make the products and nothing for IoT to monitor.
