Although they hold much promise, this has not exactly been a stellar time lately for self-driving/autonomous vehicles. As a matter of fact, recent events have cast a dark cloud over them.
Testing them on the road is, of course, essential, but I’ve often wondered if digital simulation could be used more to maximize safety and efficiency with less road testing required.
As it turns out, this very thing, simulation, is finally being performed quite extensively.
This week, Siemens introduced a breakthrough solution for the development of autonomous driving systems as an addition its Simcenter portfolio that minimizes the need for extensive physical prototyping while dramatically reducing the number of logged test miles necessary to demonstrate the safety of autonomous vehicles.
In a nutshell, this computing and simulation platform is aimed at accelerating the validation and verification of autonomous cars.
Siemens PLM Software Driving Simulator
According to the findings of a report issued by the Rand Corporation, autonomous vehicle prototypes would have to be driven hundreds of millions of miles, and in some cases hundreds of billions of miles, over the course of several decades to demonstrate their reliability in terms of fatalities and injuries – an outcome the authors deemed inconsistent with the near-term commercial viability of self-driving cars. For possible solutions to these challenges, the researchers pointed to innovative testing methods such as advanced simulation technologies.
Leveraging advanced, physics-based simulation and innovative sensor data processing technologies, the new Siemens solution is designed to help automakers and their suppliers address this industry challenge with the potential to shave years off the development, verification and validation of self-driving cars.

This week, PTC announced Creo 5.0, the latest release of its Creo CAD software that covers concept to manufacturing in a single design environment. According to the company, Creo 5.0 introduces five new and enhanced capabilities for product design and productivity enhancements in the areas of topology optimization, additive and subtractive manufacturing, computational fluid dynamics, and CAM.
“PTC is on the leading edge of some of the hottest technologies today with the Internet of Things (IoT) and augmented reality (AR), but it has not forgotten its roots in CAD, instead transforming this business by infusing its leading Creo software with new technologies and capabilities,” said John Mackrell, chairman, CIMdata.
The physical design of products is often limited by existing designs and practices. The new Creo Topology Optimization Extension automatically creates optimized designs based on a defined set of objectives and constraints, and freed of existing designs and thought processes. This helps users save time and accelerate development by enabling creation of optimized parts for given tasks they must perform.
Creo automatically creates optimized geometric forms/shapes based on input conditions and defined criteria.
The Creo Topology Optimization Extension will be available Summer 2018 in the first maintenance build of Creo 5.0.

Recently, ANSYS, known for its engineering simulation software, and MachineWorks known for its machining and verification software signed an agreement to expand the use of Polygonica Polygon Modeling Software toolkit throughout the ANSYS organization.
Polygonica is a polygonal solid modeling toolkit for processing polygon mesh and is the creator of MachineWorks.
Polygonica carries out a wide range of geometric operations on polygon mesh models such as automatic solid healing, fixing self-intersections and Boolean operations. Other algorithms in Polygonica allow remeshing, simplification, offsetting and point cloud manipulation.
Polygonica is built on MachineWorks’ core technology for material removal and machine simulation, and has a wide range of applications for many sectors, including additive manufacturing/3D printing, where solving complex polygon modeling problems is required when handling defective models with vast numbers of polygons.
Polygonica is used in ANSYS Discovery Live software, ANSYS’ relatively new tool that enables fast computation of CAE analysis results using the power of local GPUs. ANSYS Discovery Live shortens the feedback loop between design and analysis and lets product designers see relevant results immediately during the conceptual design process.
Interview with ANSYS at IMTS 2016
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.
With ANSYS Discovery Live, ANSYS hopes it will break and change that cycle.

3D printing, or more accurately, additive manufacturing (AM), has come a long way since its inception, and especially the past few years. It also continues to grow at an amazing rate. IDC forecasts worldwide spending on 3D printing to be early $12 billion in 2018
A new update to the Worldwide Semiannual 3D Printing Spending Guide from International Data Corporation (IDC) shows global spending on 3D printing (including hardware, materials, software, and services) will be nearly $12.0 billion in 2018, an increase of 19.9% over 2017. By 2021, IDC expects worldwide spending to be nearly $20.0 billion with a five-year compound annual growth rate (CAGR) of 20.5%.
Discrete manufacturing will be the dominant industry for 3D printing, delivering more than half of all worldwide spending throughout the 2017-2021 forecast. Healthcare providers will be the second largest industry with a spending total of nearly $1.3 billion in 2018, followed by education ($974 million) and consumer ($831 million). By 2021, IDC expects professional services and retail to move ahead of the consumer segment. The industries that will see the fastest growth in 3D printing spending over the five-year forecast are the resource industries and healthcare.
The leading use cases for 3D printing are prototypes, aftermarket parts, and parts for new products. As the primary use cases for the discrete manufacturing industry, these three use cases will account for 44% of worldwide spending in 2018.
As testament to this tremendous growth, this week, 3D printer manufacturer Ultimaker announced that Robert Bosch GmbH, a leading global supplier of technology and services, will invest in Ultimaker 3 Extended printers on a global scale. After comparing several desktop 3D printers, the additive manufacturing department of Bosch selected Ultimaker as the most reliable, easy-to-use, and machine that produced the highest quality parts. The printers will now be used in different locations across Germany, Hungary, China, India, the United States and Mexico for printing innovative prototypes, tooling, jigs and fixtures, while cutting design and manufacturing costs.
Ultimaker Interview at Westec 2017
As the world’s largest supplier of automotive components and an important supplier of industrial technologies, consumer goods, and energy and building technology, Bosch, has a strategic objective to deliver innovative products. In order to save time and costs, and for a faster time-to-market for its new products, the company decided to invest in desktop 3D printing on a global scale. Now, with the Ultimaker rollout, all departments of the additive manufacturing department of Bosch can benefit from a uniform 3D printing solution with materials, training and global support. This approach will ensure consistent, quality 3D printing results across teams and locations.

In the cloud-based technical/engineering platform world, IoT may be getting the lion’s share of attention at the moment, but right up there competing for relevance and significance are VR/AR technologies. As cool as they are, VR/AR technologies have been hindered from wider use primarily because of the expensive high GPU requirements needed to make them work, and well, be realistic. That’s changing, however, as cloud-based platforms bring performance and fidelity to VR/AR at much lower entry and implementation price points.
Case in point, this week a Detroit-based startup, ONU, announced a unique offering called ONU 3DLite, a cloud-based 3D visual platform designed to convert and optimize CAD files for creating visual content for 3D Web, AR, VR, or mobile-based applications. ONU provides technology to streamline 3D asset creation pipelines, automating processes that have been manual. In other words, an end-to-end, 3D asset management platform.
“Manufacturers design products in CAD, but those files don’t easily translate to visuals that can be displayed on a mobile device, let alone in a web browser, virtual reality headset, or augmented reality glasses,” said Sam Sesti, President of ONU. “ONU 3DLite changes that. Our easy to use tools automate processes that were previously manual, and significantly streamlines 3D asset creation. Native CAD files can be turned into low polygon Filmbox (FBX) files in just minutes. In addition to making asset creation really easy, it’s also very affordable. We’re excited to share ONU 3DLite with the world.”

It’s 2018, and along with being cloud based, virtually every engineering design software company has embraced the inevitability of the Internet of Things (IoT) – some better than others. SOLIDWORKS is no exception, as it announced an add-in with Seebo that will enhance its IoT presence through connected products.
Today’s manufacturers are increasingly turning to IoT to meet strategic business objectives – from improving product resilience and efficiency, to growing sales, and boosting customer satisfaction.
However, the high-rate of stalled and failed IoT initiatives – which, according to a recent Cisco study, account for a whopping 75% – continues to reflect how IoT development remains complicated, expensive, and risky.
Product teams turn to companies like Seebo to visually describe their connected products in a digital model. The Seebo platform then automatically generates the specs, simulations, and analytics to make it happen.
At the SOLIDWORKS World 2018 Conference, Seebo announced a SOLIDWORKS add-in for manufacturers to plan and deliver smart, connected products. As a new certified Gold Partner for SOLIDWORKS, Seebo launched the add-in for SOLIDWORKS users to turn their existing 3D product designs into a visual model of the entire IoT system, and get auto-generated specs, simulations, and analytics to make their products IoT connected.
Seebo and SOLIDWORKS For Planning And Delivering IoT Products
The Seebo add-in for SOLIDWORKS addresses the pains of planning and delivering IoT products. With Seebo, SOLIDWORKS users are equipped with tools for IoT modeling, simulation, execution, and behavior analytics. This allows them to quickly and easily define, validate, and build IoT products. Once in-market, product teams see exactly how their product is being used and make informed data-driven decisions about product enhancements to boost product adoption and profits.
“Mastering how to design for the Internet of Things will be one of the major challenges for companies in the next 2-3 years,” said Kishore Boyalakuntla, VP of Product Portfolio Management, SOLIDWORKS, Dassault Systèmes. “The Seebo add-in helps users seamlessly turn their existing SOLIDWORKS designs into connected products that drive outstanding customer value.”
Lior Akavia, Seebo Co-Founder and CEO said, “We are excited to be a certified Gold Partner for SOLIDWORKS, making IoT design accessible and simple to the millions of SOLIDWORKS users worldwide. Equipped with the Seebo add-in, users will be able to launch products that stand out from the competition and boost customer satisfaction with innovative capabilities, superior performance, and minimized downtime.”
According to VP of Product Portfolio Management at Dassault Systèmes SOLIDWORKS, Kishore Boyalakuntla, among the leading challenges companies are facing is “mastering how to design for the Internet of Things.”
To address these pains, SOLIDWORKS has teamed up with Seebo to make IoT design accessible to SOLIDWORKS.
With Seebo, SOLIDWORKS users have tools for IoT Modeling, Simulation, Execution, and Behavior Analytics. This allows them to quickly define, validate, and build IoT products. Once in-market, product teams see exactly how their product is being used and make informed data-driven decisions about product enhancements to boost product adoption and profits.
It takes just a few hours for SOLIDWORKS users to turn their existing 3D product designs into a visual model of the entire IoT system on Seebo’s platform. Inside Seebo, users get auto-generated specs, simulations, and behavior analytics to make their products IoT connected.

This week was the 20th edition of SOLIDWORKS World and I think I’ve been to 17 or 18 of them. Some have been great, some not so great, but every one has provided something interesting that makes the company and its impact on the MCAD community stand out. This year was no exception as it had several significant announcements.
The theme for this years SOLIDWORKS WORLD was “Think,” which was a good idea but was really more about “experience,” as in 3DEXPERIENCE which is the mantra of Dassault Systemes, and not so much about specific software products. The various experiences that were discussed ranged from 3DEXPERIENCE Design Services to the 3DEXPERIENCE Marketplace|Make that include Socual Collaboration and PLM services. I’m still trying to get my head wrapped around all of this because there was little discussion on what all this means and how it’s all tied together, but it’s an interesting direction that I’ll continue to explore and try to understand.
Dassault Systems 3DEXPERIENCE platform continues to play an increasingly prominent role at the annual SOLIDWORKS event, although this is SOLIDWORKS World, not Dassault Systemes Universe. That aside, I heard SOLIDWORKS and CATIA mentioned a couple times in the same sentence on the stage during the event — a first for me.
However, things got much better as the conference commenced in earnest with classes and the exhibition floor in full swing.
SOLIDWORKS World 2018 Day 1 Highlights
Not to be left off the Internet of Things (IoT) bandwagon, SOLIDWORKS is also making a strong charge into this market by including design elements from SOLIDWORKS mechanical, SOLIDWORKS Electrical, and SOLIDWORKS PCB. During the conference, Seebo announced a SOLIDWORKS add-in for manufacturers to plan and deliver smart, connected products. As a new certified Gold Partner for SOLIDWORKS, theSeebo add-in for SOLIDWORKS lets users transform existing 3D product designs into a visual model of the entire IoT system, and get auto-generated specs, simulations, and analytics to make products IoT connected.

It’s almost time to head to Los Angeles for SOLIDWORKS World 2018 and for many attendees, it will be a welcome relief from winter weather. This year will mark the 20th event and more than 5,000 attendees are expected.
For us, SOLIDWORKS World is all about people, products, and exchanging ideas — reacquainting ourselves with old friends and meeting new ones.
Conference Theme: Think!
Every day of SOLIDWORKS World starts with a general session with speakers that range from engineers, to industry leaders, to SOLIDWORKS executives and partners on their visions, perspectives, and ideas that provide a present and future context for the company and industry.
Day 1 – THINK: Future
The first general session is focused the future from several different perspectives. While SOLIDWORKS has been keeping specifics of the general sessions secretive, we do know the session feature the following speakers: Gian Paolo Bassi, Bernard Charles, Kishore Boyalakuntla, Richard Doyle, and Neri Oxman.
Day 2 – THINK: Innovation
Day 2 ‘s general session focuses on innovation whay it’s obviously important and how to achieve it. There will be a little something for everyone, including “Wearable Robots That Help People Walk Again” presented by Kyoungchul Kong. The other speakers include Suchit Jain, Michel Jagemann, Suchit Jain, Kishore Boyalakuntla, and Brent Bushnell.
Day 3 – THINK: Next Is Now
The final general group session includes one of our favorite parts of the conference, a peek into possible SOLIDWORKS 2019 features and capabilities. It wraps up with speakers that include Suchit Jain, Kishore Boyalakuntla, Mark Schneider, Joseph Hiura, Robert Andrew Johnson, Kurt Anliker, and Gian Paolo Bassi.
New and Improved SOLIDWORKS Products
Several SOLIDWORKS products, both new and improved, will be showcased and demonstrated on the main stage, breakout sessions, and the exhibition floor. Some of the more significant include:
SOLIDWORKS 3D 2018
Although the flagship product has been out for a few months, with SOLIDWORKS 2018, the company 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).
Some of the other major new and improved features for SOLIDWORKS 2018 include:
Inspection for MBD – With the enhancements in SOLIDWORKS 2018, you can now create inspection documentation directly from 3D models with Production Manufacturing Information (PMI), as well as from 2D drawings, PDFs, and TIFFs. SOLIDWORKS Inspection is now integrated with SOLIDWORKS PDM, and supports SOLIDWORKS part and assembly files (*.sldprt, *.sldasm), as well as non-native 3D CAD formats.
3D Interconnect – You can work with more file formats including ACIS, STEP, and IGES, and automatically update your design whenever new files are received. In addition, 3D Interconnect now supports internal file information like custom properties, materials properties and reference axes.
Working With Mesh Data – You can now work directly with mesh data as you would with surface or solid geometry. Combine, intersect, split, move/copy, cut with surface, and check for interference. In addition, you can quickly fit surface bodies to regions of mesh models.
Sheet Metal – SOLIDWORKS 2018 includes tab and slot features for self-fixturing of parts for welding. A normal cut feature ensures that clearances are included for manufacturing, and tools to easily create or flatten corners that include three bends.
Generative Design – SOLIDWORKS Simulation Topology Study tool can automatically optimize the shape of a design based on weight, function, and manufacturing criteria. You can improve performance or reduce product weight based on simulation and manufacturing constraints.
The SOLIDWORKS CAM rules-based technology enables you to integrate design and manufacturing, connecting design and manufacturing teams through a common software tool and 3D model. SOLIDWORKS CAM is an add-on to all versions of SOLIDWORKS CAD that lets you prepare your designs for manufacturability earlier in the development cycle. Manufacturing tasks that had to wait until a design was complete can now be performed concurrently with the design process.
SOLIDWORKS CAM Standard lets you quickly program individual milled parts and configurations without leaving the SOLIDWORKS 3D CAD environment. You have full access to defining rules within SOLIDWORKS CAM to create and build to company standards, as well as Tolerance-Based Machining (TBM).
SOLIDWORKS CAM Professional builds on the capabilities of SOLIDWORKS CAM Standard with increased programming capabilities. The additional features include High-Speed Machining (HSM), configurations, assembly machining, turning, and 3+2 programming to drive four- and five-axis machines.
SOLIDWORKS Visualize lets you leverage your 3D CAD data to create photo-quality content in the fastest and easiest way you can–from images to animations, interactive web content, and immersive Virtual Reality. Bring your products to life. SOLIDWORKS Visualize is the “camera” for your CAD data.
SOLIDWORKS Visualize is hardware-agnostic and can leverage one or many GPUs in a single machine or across a network, which dramatically increases rendering performance over CPU hardware.
SOLIDWORKS Visualize Standard lets you produce photo-quality images for taking “photos” of 3D data, cutting costs, and accelerating time-to-market with compelling imagery.
SOLIDWORKS Visualize Professional lets you tell a deeper story with your CAD data by generating photo-quality imagery, interactive animations, 360-degree spins, and immersive Virtual Reality (VR) for communicating complex design details.
SOLIDWORKS Model-Based Definition (MBD) lets you define and organize 3D dimensions, tolerances, datums, notes, Bills of Material (BOMs), and other annotations; customize publishing templates for manufacturing, such as Part or Assembly Specifications, Request for Quote (RFQ), and Incoming Inspection Reports. You can also publish to widely accepted formats, such as eDrawings, STEP 242, and 3D PDF for clear 3D communications.
SOLIDWORKS MBD helps you define feature-based annotations in Parts and assemblies (DimXpert), and import 3D annotations from common CAD formats for more efficient design collaborations.
When there are too many 3D annotations, you can show and hide annotations automatically as a model rotates, capture comprehensive settings with 3D views similar to visual bookmarks, compare 3D annotation differences between revisions to capture subtle but critical differences, and reuse 3D views in 2D drawings when necessary.
I don’t know a lot about this product yet, but suffice it to say this could be a real cloud-based game changer for SOLIDWORKS.
SOLIDWORKS Xdesign combines ease of use with innovative design methodologies and cloud collaboration from inside your browser. Create parametric models and assemblies, or let Xdesign’s Design Guidance suggest solutions. Share designs and collaborate through communities.
Being cloud-based, with no software to install configure or manage, you are always working with the latest version of Xdesign on all your devices.
With the single modeling environment, there is no need to worry about parts and assemblies. Top-down or bottom-up—Xdesign supports design needs and automatically creates a design structure.
When facing tough structural design challenges, Design Guidance can offer possible solutions. Simply provide the part connection points and force conditions and Design Guidance will give you insight into what your part should look like. Keep it as a guidance reference or use it in your model.
Not too much to discuss here yet, but a preview of what the future might hold will be presented the final day of the show during the morning’s general session. More on this and what we might expect to see in the next release will be covered next week.
We’ll be on the lookout for innovative companies, products, and services. Next week I will discuss what I considered to be “Best of Show” for hardware, software, and service.
Meet Us At SOLIDWORKS World 2018!

For quite some time, I’ve been saying to my peers and detractors that 2018 might finally be the year the “cloud” takes off, whether we’re talking storage in the cloud, CAD in the cloud, simulation in the cloud – whatever in the cloud. I also think that another “cloud” innovation that will get its just attention is the point cloud that will grow far beyond its traditional role for representing surfaces to becoming an integral component of 3D modeling and maybe even virtual reality.
So, exactly what is a point cloud? Technically, a point cloud is a data base containing points in a 3D coordinate system. A point cloud is a very accurate digital record of an object or space. It is saved as a (very) large number of points that cover surfaces of a scanned/sensed object. The points in a point clouds are always located on the external surfaces of visible objects, because they are the points reflected from scanned objects.
In a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and intended to represent the external surface of an object.
Point clouds can be created by several methods, including 3D scanners and photographs. These devices measure a large number of points on an object’s surface, and often output a point cloud as a data file. The point cloud represents the set of points that the device has measured.
Reality Capture – Converting Photos Into 3D Models
The key factor in acquiring point cloud data is the access/visibility to scanned surfaces. It is important to remember, that point clouds are created with visible access to real objects. Regardless of the method of acquisition (scanner or photos). It is impossible to obtain points on the surfaces that are not visible from the position from which data is collected. This means that to cover entire objects, many scanning positions must be combined.
