L&H Design Werks Migrates and Benefits from Kenesto’s True Cloud Vault

 
November 9th, 2017 by Jeff Rowe

Like many small- and medium-size businesses contemplating a PDM system, L&H Design Werks wondered what PDM could do for them. The Coopersville, Michigan-based company designs customized production machines, but also designs fixturing, and robotic cells, with experience in welding, metal forming, automotive glass and high-speed material handling applications. L&H has also done a considerable amount of conceptual design. All these capabilities demand that design and associated data be managed with a secure PDM system that can be accessed by those needing the data. It was secure data management and access that prompted L&H to make the decision to implement a PDM system in the first place.

Since 2005, L&H Design Werks has been using SOLIDWORKS as its primary design tool, largely because it perceived its industry moving toward it, and they saw SOLIDWORKS as being a more flexible a tool than some of the other CAD packages they had evaluated.

After the CAD tool was in place, what prompted L&H Design Werks to consider PDM in the first place? According to Brian Land, CEO of L&H Design Werks, “We wanted to be able to have more than one person work on a project/design at a time. We started with SOLIDWORKS PDM Workgroup because it was relatively inexpensive and fairly straightforward to use. We started using it right away with our first purchase of SOLIDWORKS.”

The Move to Kenesto PDM

While L&H was satisfied with SOLIDWORKS PDM Workgroup for a while, it started to look for alternatives because SOLIDWORKS decided to no longer offer Workgroup PDM and wanted the company to move to SOLIDWORKS PDM Enterprise. “Because we are not very large, we like to keep things basic. I felt Enterprise had more bells and whistles than we needed. We like the keep it simple, stupid (KISS) approach,” said Land.

“Also, one of our customers wanted to be able to easily access our CAD files. That way if they made changes on the floor it was immediately updated, so that we saw the changes as soon as they did. I also knew that cloud-based storage seemed to make the most sense moving forward for safety in knowing it’s always backed up. That’s when we seriously looked at Kenesto as an alternative and replacement, and have been using it for the past several months. We have been putting some of our older projects up to Kenesto and put all new projects there.”

Land said, overall, his experience with Kenesto has exceeded his expectations. “The people I have dealt with at Kenesto are all excellent, going above and beyond to help us out. We had some problems in the beginning that were a result of some of our equipment and setup, and they helped us to get in the right direction and it’s made a big difference. There have been some glitches from time to time, but most of those problematic issues are related to SOLIDWORKS, and not Kenesto.”

Theorem Solutions Democratizes Different Realities

 
November 2nd, 2017 by Jeff Rowe

It seems that everybody wants in on the action in the various “realities” game. Case in point — Theorem Solutions, a company known largely for its product data interoperability and PLM has launched a Multi-Device Visualization Experience App for Augmented (AR), Mixed (MR), and Virtual Reality (VR) devices and markets.

Traditionally, Theorem’s products and solutions have enabled companies to leverage their CAD and PLM assets in other parts of their business, primarily in data sharing with downstream processes and suppliers, and now in the emerging Augmented, Mixed, and Virtual Reality sectors.

The Visualization Experience app forms part of Theorem’s Digital Realities product family, and has been specifically developed for users to engage and interact with their Engineering and Manufacturing data. It is one of the first to offer a single solution for all three different technologies in a single application.

What are Virtual and Augmented Realities?

The Multi-Device application is a single application built from the ground up using the latest graphics gaming engine, producing stunning graphical representations of your data, which is a real game changer to the world of traditional CAD graphics and visualization.

Supported devices include:

  • Augmented Reality – Windows 10 and Android Tablets and Phones
  • Mixed Reality – Microsoft HoloLens
  • Virtual Reality – HTC Vive and Oculus Rift

Being Multi-Device, the application allows users to use the same data, in the same visualization application, on all the different low-cost devices.

NVIDIA’s AI Computer Drives AVs

 
October 19th, 2017 by Jeff Rowe

This week NVIDIA unveiled what it claims to be the world’s first artificial intelligence computer designed specifically to “drive” fully autonomous vehicles.

The new system, codenamed Pegasus, brings the NVIDIA® DRIVE™ PX AI computing platform for handling Level 5 driverless vehicles (Level 5 is ”steering wheel optional.” In other words, no human intervention is required, for example, a robotic taxi). NVIDIA DRIVE PX Pegasus can perform over 320 trillion operations per second — more than 10x the performance of its predecessor, NVIDIA DRIVE PX 2.

NVIDIA DRIVE PX Pegasus is intended to help make a new class of vehicles possible that can operate without a driver — fully autonomous vehicles without steering wheels, pedals, or mirrors, and interiors that feel more like a living room or office than a vehicle. They will arrive on demand to safely take passengers to their destinations, bringing mobility to everyone, including the elderly and disabled.

One of the driving forces behind autonomous vehicles is to recapture millions of hours of lost time that could be used by “drivers” (really passengers) to work, play, eat or sleep on their daily commutes. Theoretically, countless lives could be saved by vehicles that are never fatigued, impaired, or distracted — increasing road safety, reducing congestion, and possibly freeing up land currently used for parking lots.

Of the 225 partners developing on the NVIDIA DRIVE PX platform, more than 25 are developing fully autonomous robotaxis using NVIDIA CUDA GPUs. Today, their trunks resemble small data centers, loaded with racks of computers with server-class NVIDIA GPUs running deep learning, computer vision and parallel computing algorithms. Their size, power demands and cost make them impractical for production vehicles.

NVIDIA AI Vehicle Demonstration

The computational requirements of robotaxis are enormous — perceiving the world through high-resolution, 360-degree surround cameras and lidars, localizing the vehicle within centimeter accuracy, tracking vehicles and people around the car, and planning a safe and comfortable path to the destination. All this processing must be done with multiple levels of redundancy to ensure the highest level of safety. The computing demands of driverless vehicles are easily 50 to 100 times more intensive than the most advanced cars today with human drivers.

PTC Marches On With New Vuforia AR Platform Release

 
October 12th, 2017 by Jeff Rowe

This week PTC announced the upcoming release of the newest version of its Vuforia platform for AR development, Vuforia 7. The company says Vuforia 7 will introduce major advancements in the ability to attach digital content to more types of objects and environments, and a new capability for delivering enhanced AR experiences on a wide range of handheld devices.

PTC claims that Vuforia is the world’s most widely used platform for AR development. With support for mobile phones, tablets and eyewear, Vuforia has powered more than 475 million installs of AR apps from the App Store and Google Play. Vuforia Engine, the core of the platform, uses a device’s camera(s) and sensors to function as a digital “eye” inside an app. It “sees” objects and surfaces where content can be placed, and enables developers to create AR experiences using existing development tools.

Vuforia 7 will introduce Model Targets, a new feature for attaching content to objects that have not been recognizable using existing computer vision technology. Model Targets recognize objects by shape, in contrast to existing methods that rely on detailed visual designs typically found on print media, product packaging and many consumer goods. With Model Targets, content can be attached to objects such as automobiles, appliances, and industrial equipment and machinery. Model Targets will enable a new class of AR content that can replace traditional user manuals and technical service instructions.

Jay Wright, President, Vuforia: State of Augmented Reality

Responding to developers, Vuforia 7 will also introduce a new capability for placing content on horizontal surfaces. Vuforia Ground Plane enables content to be placed on the ground, floor or tabletop, whether indoors or outdoors. Vuforia Ground Plane extends the functionality of the Vuforia Smart Terrain feature, first announced in 2013 to take advantage of depth sensing cameras. Vuforia Ground Plane will support a wide range of today’s devices and provides an ideal solution for developers to build visualization apps, ranging from in-home furniture shopping to design review.

Dassault Systemes Acquiring Exa for CFD

 
October 5th, 2017 by Jeff Rowe

It seems that a lot of CAD companies have taken a greater interest in digital simulation the past several years. Case in point — the recent MSC Software acquisition by Hexagon. That high level of interest was again evidenced this week as Dassault Systèmes and Exa Corporation with its simulation software for product engineering, announced the signing of a definitive merger agreement for Dassault Systèmes to acquire Exa. Under the terms of the merger agreement, this represents a value for Exa of approximately $400 million. Exa’s fiscal year ended January 31, 2017 and its revenue was $72 million.

With the addition of Exa, Dassault Systèmes’ 3DEXPERIENCE platform will provide customers with a mature, diverse portfolio of combined Lattice Boltzmann fluid simulation technologies, as well as Exa’s fully industrialized solutions and approximately 350 experienced simulation professionals. Because of its solving method, Exa’s solutions can solve fluids problems faster and more accurately than traditional methods for aerodynamics, aeroacoustics, and thermal management.

STEM Provides Roots and Growth

 
September 28th, 2017 by Jeff Rowe

A debate continues to rage about America’s general decline in science, engineering, and technology, largely blamed on the first steps of our youngest citizens – math and literacy education.

A couple of years ago I taught math to middle and high school students and witnessed firsthand not only the challenges, but also the opportunities for positive change brought about by a belief and commitment to teaching.

From my perspective, I learned that I taught to overcome two different but related needs – innumeracy (unfamiliarity with mathematical concepts and methods and the inability to use mathematics) as well as illiteracy (the inability to read and write). They both go hand in hand, because as important as getting the numbers right is, the ability to provide a convincing argument and communicate the numerical answer of the “why and how” is just as important.

Quality Information Framework: The Digital Thread For Interoperability

 
September 21st, 2017 by Jeff Rowe

Interoperability, collaboration, inspection, quality, standards, proprietary data, neutrality, competition, and innovation. Over the years there have been myriad attempts to bring these processes together, all while protecting IP. However, as we know, while the attempts to make this happen have often been valiant, too often they have fallen well short, or worse, failed altogether.

That legacy of failure is on its way to being a thing of the past with the advent of the Quality Information Framework (QIF), an ANSI standard that supports digital thread concepts in engineering applications ranging from product design through manufacturing. Based on the XML standard, it contains a Library of XML Schema ensuring both data integrity and data interoperability in Model Based Enterprise (MBE) implementations.

QIF supports design, metrology, manufacturing, and is critical to the Industrial Revolution 4.0. Because it is XML based, QIF can be relatively easily integrated with Internet applications, and unlike other existing standards, there is no real barrier standing in the way for industry adopting QIF. It also effectively supports newer technologies, including additive manufacturing and the Internet of Things (IoT).

First Look At SOLIDWORKS 2018

 
September 14th, 2017 by Jeff Rowe

Well, another Labor Day has come and gone, and summer is almost over, but that means that a new version of SOLIDWORKS is about to launch. It actually and officially launched earlier this week.

I spoke with Kishore Boyalakuntla, SOLIDWORKS Vice President, Portfolio Management and Brand UX Leader about what was new in SOLIDWORKS 2018, and there was a lot to cover. Keep in mind, though, that I’ll just be touching on what I consider to be the highlights in SOLIDWORKS 2018 this time around. In the coming weeks and months I’ll be going into much more detail on the new version’s features and capabilities

Design To Smart Manufacturing

This time around, SOLIDWORKS says its design-to-manufacturing process provides the tools needed to implement a comprehensive design-through-manufacturing strategy, all inside the SOLIDWORKS environment. These tools let you work without having to export and import data from one system to another. With IP embedded in the 3D design model, and at the center of the model-based definition (MBD) process,, and thanks to associativity, changes from design or manufacturing are automatically reflected in all related CAD models, CAM programs, drawings, and documentation.

Additionally, all the information for manufacturing, inspection, and simulation and verification is directly linked to the design, so it always reflects the current design iteration (which is always a good thing).

ANSYS Discovery Live Accelerates Engineering Simulation For Concept Exploration

 
September 7th, 2017 by Jeff Rowe

Even though we’ve been told by a number of software vendors for several years now to use engineering simulation and analysis at the earliest stages of product development, relatively few companies have heeded the advice and actually done so. In many cases, it’s still design, break, repeat in a cycle that gets very expensive quickly trying to achieve optimized design goals. Even with all the insistence and chiding from the simulation folks, I’d estimate the percentage of design work that includes simulation early in the process as somewhere between 20-25%, although that may be a bit on the high side.

This week, ANSYS presented a technology preview of what it hopes will break and change that cycle with what it calls ANSYS Discovery Live .

With it, engineers can rapidly explore design options and receive accurate simulation results with technology using engineering simulation to make digital exploration available to all engineers so they can design better products faster and more economically.

That’s a pretty confident and heady statement, knowing that several other vendors have attempted the roughly same thing with widely varying degrees of success. However, ANSYS has an interesting and innovative approach for reaching its goal — exploiting GPUs because they can handle massively parallel operations.

ANSYS readily admits that while Discovery Live is a means of bringing simulation to the engineering masses earlier in the development process, it doesn’t pretend to do everything for everybody, and there will always be a place for engineering simulation specialists for deeper dives. Discovery Live is targeted to early design exploration and to users new to simulation. Because it is not a solution for every simulation problem, Discovery Live does not compete with other more advanced ANSYS products, such as AIM, but data from it can be exported for more further study.

The Ongoing Software Patent Debate

 
August 31st, 2017 by Jeff Rowe

A couple years ago I got into a pretty heated discussion with a staffer from an engineering software company about whether software patents were still relevant (or is they ever were to begin with).

While proponents (usually with deep pockets) have touted their benefits, software patents have also been used in the software industry to suppress innovation, kill competition, generate undeserved royalties, and make patent attorneys rich. So I’ll ask again, are software patents still relevant?

It’s no secret that the engineering software business is extremely competitive, as it always has been. Without naming names, the engineering software business has also proven to be a very fertile and lucrative ground for lawsuits regarding patent infringement, reverse engineering, and outright copying and pasting blocks of code.

Could stronger patent protection have prevented this from happening? Maybe yes, but probably, no.

Below is a video on the futility of software patents featuring Linus Torvalds, the creator, and for a long time, principal developer of the Linux kernel, which became the kernel for operating systems such as the Linux operating system, Android, and Chrome OS.

Linus Torvalds: Why Software Patents Make No Sense

Software patents have been hotly debated for years. Opponents to them have gained more visibility with less resources through the years than pro-patent supporters. Through these debates, arguments for and critiques against software patents have been focused mostly on the economic consequences of software patents, but there is a lot more to it than just money.
