Vistagy has been a long-term third-party partner not just to Siemens PLM, but also to Dassault Systemes. Though DS has its own composite design solution, many of its most important customers use Fibersim. To say Vistagy has been an important partner for DS would be an understatement.

My interest in Vistagy is as a microcosm of the relationship between Siemens PLM and Dassault Systemes. Let’s face it: These two companies are serious competitors. Has Siemens acquisition of Vistagy upset a tenuous détente (if it can even be called that) between these two giants of PLM?

This week at Siemens PLM Connection, I got a chance to speak with Steve Luby, the current Sr. VP of Siemens’ Specialized Engineering Software business segment, and former CEO of Vistagy. He told me that he’d always been careful in maintaining Vistagy’s relationship with DS. Since Vistagy had been a long-term partner to both DS and Siemens PLM, he got used to treading carefully. Since the Siemens acquisition, Luby explained, DS has not done anything precipitous (such as tossing Vistagy/Siemens out of their partner program.)

But that’s not surprising. Doing that would be the equivalent of mutually assured destruction. It’d be tough to explain to the biggest aerospace firms in the world that, oops, they can’t use Vistagy’s products anymore.

My guess, though, is that DS is focusing big energy on improving their composite solution (which I understand is mighty competent already), with the eye to displacing as many seats of Fibersim as they can. Yet, even in the best of all worlds, that’s going to be hard to do. I can’t imagine Boeing, for example, dropping Fibersim from the toolset used on the 787 Dreamliner—a plane that’s 50% composites by weight.

I don’t anticipate that DS is going to open their doors, and let Siemens/Vistagy have completely unfettered access to their APIs (and customers!) The current Vistagy products, including applications for composites, airframe fasteners, and automotive/aerospace seating, are probably grandfathered in. But future Specialized Engineering (i.e., Vistagy) products?

It’s a big wild-card. The new Codex of PLM Openness that both DS and Siemens recently signed would suggest that the companies are going to play nicer together than they have in the past. Yet, my reading of the Codex is that it gives an awful lot of wiggle room.

The Siemens Vistagy acquisition presents a nice public context for DS to show that they’re committed to openness. To playing (competing) nice. If my reading between the lines is right, the situation is “so far, so good.” If you’re a Vistagy customer, and you hear anything different (good or bad), I’d sure like to hear about it.

3D CAD Tips

The public lashback on cloud CAD started building several years ago, and it’s hardly abated since. The conversation has taken on political/religious overtones.

In the best of all worlds, clould CAD could be a revolutionary tool, allowing people to work where, when, and with whom they desire. The troika of cloud, mobile, and social offer intriguing possibilities.

Yet, there are potential problems with cloud CAD, at multiple levels.

The issues are substantial enough that it’s not practical to address them all at once. So, with this article, I’ll dig into with just one issue: the difficulty in actually creating a cloud CAD program.

CAD is difficult

CAD, even without being cloud-based, is difficult to create. Mike Riddle, one of the best known CAD architects, estimates that CAD is about an order of magnitude more complex than typical Office type applications. He ‘s not talking about lines of code (though CAD programs do clock-in with tens of millions of lines of code.) Rather, he’s referring to the Chess-like complexity and difficulty of creating a CAD program that can actually model the things that its users want to model.

Understanding CAD architecture

CAD programs are built up out of a large number of software components. Some, such as geometric modeling kernels, constraint managers, graphics pipelines, and translators, are developed by fairly well-known companies, and licensed to a large number of CAD developers. Other components, such as those for manipulating raster images, zip files, or unicode characters, are available through open-source repositories, such as SourceForge. Many more components are created by CAD developers themselves.

The real magic in creating a CAD program comes in how the software compenents are arranged and connected. This is the essence of software architecture. It is largely what distinguishes great programs from lousy programs.

Once the architecture for a CAD program has been set, it can be really difficult to change.

Consider, for example, how CAD programs, almost as a rule, seem to take very poor advantage of multi-core processors. This isn’t because the CAD vendors (and the programmers who work for them) don’t want to provide good multi-core support. It’s because the architecture of their software, and of the component libraries which comprise their applications (particularly the geometric modeling kernel, if we want to point fingers) were not initially designed to support concurrency (the underlying requirement to support multi-core processors.)

Though CAD vendors could rip their software down to the ground, and re-architect it to support concurrency, it’s not so easy as just putting a team of programmers on it, and giving them a budget for coffee and Red Bull.

CAD software architectures generally creep, in an organic fashion, from release to release. Initial versions of CAD programs are often architecturally consistent because they are created by small development teams comprised of very experienced CAD programmers. Yet, over time, demands to add new features and capabilities on too-short schedules, and the addition of more programmers to development teams, can lead to hacks which compromise the architectural integrity of later versions of the software.

The result can be a CAD program that works pretty well in most cases, but which has persistent instabilities that can’t be easily fixed—either because no one actually completely understands the CAD program’s architecture, or the instability has become “baked into” the architecture. (Not to point fingers, but there are a number of well-known CAD programs which suffer from persistent instability.)

For a CEO of a CAD software company, the prospect of embarking on a re-architecture project has got to be chilling. Too many of these projects (the most infamous being AutoCAD Release 13) end up being expensive disasters.

Cloud CAD architecture

There are two ways to approach cloud CAD. One way is to use an existing desktop (e.g., Windows, OSX, or Linux based) CAD program, and run it, mostly unchanged, on virtualized servers. This is the approach that companies such as Citrix and CloudSwitch enable—and it’s nothing new. The other way is to build a CAD architecture that’s optimized for use on the cloud.

An optimal cloud CAD architecture would support scalability, both in the number of concurrent users, and in the size of CAD models. That means, essentially, breaking the CAD software down in to a number of interoperable services, which can run concurrently on multiple loosely-coupled server instances.

The problem that CAD developers run into is that, even though their existing desktop CAD systems are built from a large number of software components, those components were never designed to work in a loosely-coupled environment, and they were not, except in rare cases, designed to support concurrency. It’s simply not practical to take an existing CAD program, break it down to its components, then use those to build a cloud CAD system.

The only practical way to build a scalable cloud-based CAD system is to start from scratch, with a new architecture. While some components from existing CAD systems may be reusable as is, most are not.

Where are the cloud CAD programs?

The buzz about cloud CAD started in early 2010, with DS SolidWorks Corp previewing the cloud-based SolidWorks V6 at their user conference, and Autodesk opening up Project Butterfly, a cloud-based CAD application, on their Autodesk Labs site.

SolidWorks V6, despite its name, is built on the Dassault Systems V6 platform. It won’t be available until 2013, at the earliest, and even then, it won’t be entirely compatible with today’s SolidWorks program (because, among other reasons, it will be using a different geometric modeling kernel—one that’s quite different from the Parasolid kernel used in SolidWorks for the last 17 years.) SolidWorks V6 will be a functionally different program than SolidWorks.

AutoCAD WS, the released version of Project Butterfly, is the only notable cloud CAD application currently available. Despite its name, it’s not based on AutoCAD. It’s based on technology developed by PlanPlatform, a company acquired by Autodesk in 2009. While it does read and write AutoCAD compatible DWG files, AutoCAD WS is not a functional match to AutoCAD.

What of the other cloud CAD products?

There are none that are notable. (Or, rather, I don’t know of any that are particularly notable. I expect someone will send me straight on this if I’m wrong.)

While it’s possible that Siemens PLM or PTC have secret projects to develop cloud-based CAD programs, it’s likely that, if they do, those programs won’t be a functional match to their existing desktop CAD programs. Just like DS SolidWorks and Autodesk, they’ll need to start from scratch with cloud-based CAD.

Desktop CAD is here to stay

There are many CAD-related things you can do well on the cloud, including storage, rendering, CAE, and collaborative markup. But CAD itself? It’s easier to say than to do.

Cloud CAD is really difficult, if you want to do it right. As much as CAD company CEOs might like to talk about their visions of the future, they know that cloud CAD won’t replace desktop CAD for a very long time, if ever.

3D CAD Tips

The biggest reason more companies don’t use engineer-to-order software is that the front-end configuration, to set up an ETO system, has often been too much work, requiring lots of training and expensive consultants.

Tacton makes a SolidWorks-based tool for ETO: TactonWorks. They just issued a press release reporting that one of their customers, Mitsubishi Heavy Industries, has seen a 90% time savings in engineering work for custom orders. This after only having used the software for about 3 months.

The press release gives no clue as to how much work it was to configure TactonWorks with their SolidWorks models. While I suspect it was fairly easy, the fact that they’re saving 90% time within 3 months of starting suggests that it wasn’t all that hard, and that buying TactonWorks was a home-run for Mitsubishi.

Here is the press release:

Mitsubishi Heavy Industries Compressor (MCO) Chooses TactonWorks for Customization of Large Scale Compressors and Turbines

Stockholm, Sweden – April 16, 2012- Mitsubishi Heavy Industries Compressor Corporation, (MCO) began using TactonWorks in 2011 and has already seen drastic time savings for detailed engineering work of up to 90% per quote.

MCO, a 100% owned subsidiary of Mitsubishi Heavy Industries, Ldt. (MHI) is a leading global supplier of large scale compressors and turbines used at petrochemical plants, natural gas processing plants, LNG Plants, FPSD, etc. in more than 60 countries.

TactonWorks, an add-in to SolidWorks, is Tacton’s tool for Design Automation. It automates the customization of complex products, which helps you save time and money. It also ensures correctly updated models and drawings.

Not long ago, MCO saw a need to automate the customization of their products in order to reduce delivery time and engineering costs. Their reseller, Hiroshima Daia Systems HDS learned about Tacton and TactonWorks at SolidWorks World Japan in 2010. MCO implemented TactonWorks for the first section of their assembly three months ago and have already experienced detailed design time savings of approximately 90% per customization.

“We are amazed at the amount of time we’ve saved since starting to use TactonWorks—and this after implementing it in only one part of our product assembly. We really believe in this solution and are eager to start using it for our other models as well”, says Mr.Yasuhiko Omi, Director of Plant Engineering Division at Technology Management Center, MCO.

MCO plans to continue to implement TactonWorks for the other parts of their assembly with a final goal of having the complete assembly implemented.

“We are very happy to see a customer get such fantastic return after using our solution for only a short period of time. We look forward to seeing how much more time they will save in the coming phases of the project”, says Christer Wallberg, CEO Tacton Systems.

The sale was made together with Tacton’s Japanese partners, Hiroshima Daia Systems (HDS), who implemented the solution and Kozo Keikaku Engineering (KKE), who sold the software licenses.

Creo 2.0

This release includes fresh and updated releases of the 9 existing Creo apps, and adds a 10^th new app called Options Modeler, which supports design-to-order and assemble-to-order. Picture, if you will, the kind of capabilities that major PTC customers such as Caterpillar and Deere might need, and you’ll get an idea of what Options Modeler is about. It integrates with Windchill, and can handle arbitrarily large and complex assemblies. It’s available today an extension to Creo Parametric and will be available as a stand-alone app in June.

With the new release, PTC is offering the free Creo Sketch app for Apple devices, and Creo Layout for doing 2D layouts as a front-end to 3D design.

Overall, PTC has added more than 490 enhancements througought the Creo like. PTC says that the quality, performance and usability of version 2.0 of the entire Creo family is dramatically improved from version 1.0.

Windchill 10.1

PTC has integrated Integrity with Windchill, and are leveraging it for comprehensive requirements management. Integrity is the tool PTC customers will use to capture and, ultimately, trace customer requirements across the product development lifecycle to ensure the product delivered most perfectly matches the product desired. Of particular note: PTC is using Integrity to manage requirements in its own development processes.

PTC has enhanced Windchill in several key areas, adding capabilities to help users ensure compliance with government relations and with industry quality standards. One important enhancement is the ability to monitor for the use of “conflict minerals” in a given product. They’ve also improved how reliability analysis is communicated, to ensure faster resolution of issues stemming from customer complaints.

With the introduction of Windchill Mobile, PTC is now supporting the iPad and iPhone. The software includes the “shake and break” feature demonstrated at last year’s PlanetPTC Live, in which users can “explode” the diagram of a product assembly by simply shaking their mobile device to see the internal parts in greater detail. I suggested an Etch-a-Sketch function, where turning it upside down and shaking it would erase your project files—but the PTC people told me that Microsoft already had a patent on that function, back from the days of Windows ME.

The official press releases follow:

PTC Advances MCAD Strategy with Release of Creo 2.0

Latest Release Introduces New App for Modular Product Design, Enhances Apps for Concept Design, and Improves User Productivity Across Creo Family

NEEDHAM, MA. – April 9, 2012 – PTC (Nasdaq: PMTC) today announced Creo® 2.0, the latest release of its revolutionary new generation of product design software.  Last June, PTC challenged the industry paradigm with the introduction of the first nine “apps” in its Creo family – conceived, in part, to enable a much wider range of roles to contribute to the design process with a set of integrated, purpose-built tools.  With Creo 2.0, PTC introduces a new role-specific app supporting modular product design that extends how organizations can approach concept design, and delivers significant productivity enhancements to its existing Creo apps.

“The release of Creo 2.0 demonstrates PTC’s unwavering commitment to deliver against our Creo strategy and solve the chronic challenges customers face with traditional CAD tools,” said Michael Campbell, divisional general manager MCAD segment, PTC.  “Built on PTC’s heritage of innovation, Creo rethinks the very nature of product design, increasing collaboration and protecting data fidelity across any user role, any design mode, or any data source.  Today, PTC is also delivering the first technology component in its vision for managing modular product designs driven by the bill of materials.”

Modular Product Design

With Creo 2.0, PTC introduces a 10^th app to the Creo family – Creo Options Modeler™ – a new role-specific app built for designers who need to create or validate modular product designs in 3D early in a design cycle.  The new app, available this summer, delivers a dedicated, easy-to-use, powerful set of capabilities to build accurate, up-to-date, precise 3D-based product assemblies, irrespective of size or complexity. When used with Creo Parametric™, Creo Options Modeler enables teams to validate precise mass, center of gravity, and even check and resolve critical issues like interference for modular designs.

Creo Options Modeler contributes to PTC’s AnyBOM™ Assembly technology vision, which promises to give teams the power and scalability needed to create, validate and reuse information for modular product architectures.  By combining Creo Options Modeler with PTC’s Windchill® product lifecycle management software, manufacturers can generate and validate precise 3D representations of product configurations defined by an individual bill of materials.

By enabling easier reuse of existing 3D models and through innovative interface tagging, the new app can reduce process errors and engineering rework.  As a member of the Creo product family, Creo Options Modeler also seamlessly leverages and shares data between other Creo apps, and with other people involved in the design process and beyond, further increasing detailed design and downstream process productivity.  

Rethinking Concept Design

Many companies prefer to start concept designs in 2D to quickly explore multiple options before moving to build more complex 3D models.  With Creo 2.0, PTC delivers on its vision for enabling companies to make the most of this early stage of their product development process.  The new releases of Creo Parametric, Creo Direct™, the free Creo Sketch™ (now available on Mac OS X with this release), and Creo Layout™ combine to greatly enhance collaboration, innovation and design exploration during concept design.  Since all Creo apps share a common data model, 2D geometry and design data can be easily shared by all users and apps and can be re-used later in the design process to accelerate the transition to the detailed design phase.

In Creo Layout 2.0, PTC is helping to solve the specific problem of transitioning from 2D to 3D, allowing users to easily create a layout of complex assemblies, quickly explore design alternatives, import a variety of 2D CAD file types, sketch and modify 2D geometry, organize information with groups, tags and structure as well as dimensions, notes and tables.  Once created, a 2D design in Creo Layout can serve as the basis for 3D models, allowing users to create assemblies in 2D or reference 2D geometry to create part features, and any changes made in 2D are reflected in 3D upon regeneration.

Productivity Enhancements

In the new release, PTC delivers more than 490 enhancements to the Creo app family, all designed to optimize the user experience and increase design productivity. 

Creo Parametric enables increased productivity and streamlining of the overall product design process with:

·        Freeform Surfaces – With the enhanced freestyle capabilities, designers can quickly and easily create more refined surfaces with higher levels of detail while still maintaining top level control over the general freeform shape. This significantly reduces the time to move concepts to precise, highly-detailed aesthetic product designs.

·        Cross-sections – Designers working in 3D cross-sections gain complete product insight with new, intuitive, and fast ways to create and dynamically re-position the sections, including instant access directly from the model tree.  Real-time interference detection within a section together with 2D visualization helps designers fully visualize the design, design changes, and detect and address potential issues early.  The new tools significantly enhance productivity when working in cross-sections and provide a rich design environment that accelerates the overall design process.

·       Measure – The new streamlined measure tool offers significant performance and usability improvements.  Designers can quickly gain detailed insight into key dimensions and measurements of any selected surface.  By controlling how and where measured results are displayed on-screen, and allowing for simple re-use of the displayed values into other applications, such as a Word document, designers can improve the efficiency and accuracy of leveraging precise measurements during the design process.

·        Track Changes – The new track changes capability in Creo Parametric allows designers to view, accept or reject model changes made by others using Creo Direct.  Designers can now work with a broader range of roles across the company while still maintaining full control of how changes are reflected in the parametric model.  This ensures design intent is fully maintained. Irrespective of modeling approach or Creo app, teams can now truly work together.

Overall, Creo Parametric delivers state-of-the-art user experience, new capabilities, automates common tasks, improves performance with streamlined workflows and enables dramatically improved overall design productivity.

Beyond Creo Parametric, PTC delivers significant enhancements to other Creo apps.  New capabilities in Creo Direct help accelerate bid-proposals and early concept design.  Casual users can now quickly and easily create new compelling 3D designs.  They also can easily modify models by reference to existing geometry of available parts and assemblies or quickly, but precisely place multiple parts and assemblies into position with the new intelligent snapping capabilities.

And as Creo Direct seamlessly works with Creo Parametric and other Creo apps, any 3D design can be shared by users across the enterprise design process.

In addition, this latest release greatly simplifies the installation process for Creo, only downloading and installing the Creo apps specific to a customer’s environment and license entitlement. This speeds download and significantly simplifies installation and configuration enabling teams to get up and running with Creo more quickly than ever before.

More information will be shared at PTC’s upcoming annual user event, PlanetPTC Live.

PTC Extends Windchill Capabilities, Integrates with Integrity

Company Leverages Integrity for Comprehensive Requirements Management

NEEDHAM, MA. – April 9, 2012 – PTC^® (Nasdaq: PMTC) today announced the latest version of its Windchil^l® product lifecycle management (PLM) software, which is now also integrated with PTC’s recently acquired Integrity™ software system lifecycle management technology.  Windchill 10.1 introduces sweeping enhancements to the product’s capabilities in a wide range of areas, while integrating Windchill with Integrity raises the bar for how manufacturers gather and manage requirements and trace related changes.  In addition, Windchill Mobile™ is now available from the Apple iTunes store for the iPad and iPhone.

“At PTC, our goal is to help manufacturers find new ways to compete in their markets, and to make their success repeatable over time,” said Brian Shepherd, executive vice president, PLM Segment, PTC.  “With this new version of Windchill, we’ve not only enhanced a number of critical functional areas, but we’ve also made major improvements to the user experience and serviceability of the product across-the-board.  We believe that PTC is continuing to set the pace for the value companies can generate when they deploy enterprise-class PLM technology.”

Do More: Comprehensive Requirements Management from Integrity

Less than a year after being acquired by PTC Integrity is dramatically expanding PTC’s footprint of capabilities.  Specifically, PTC has integrated Windchill and Integrity to combine the rich, collaborative requirements authoring and management capabilities of Integrity with the powerful “flow-down” traceability offered in Windchill.  This combination delivers powerful, comprehensive requirements management capabilities and enables manufacturers to improve product quality, reduce rework and improve time to market.

In addition, Windchill now integrates with the software change and configuration management capabilities of Integrity – and other leading tools – to manage defects and issues, as well as enable software releases to be synchronized with product configurations.

Requirements gathering and management is one of the most critical aspects of a product’s lifecycle.  According to industry analyst firm CIMdata, “Requirements management is all about balance—preventing one class of requirements from overriding another is critical. Effective requirements management ensures that the voice of the customer is captured and managed throughout the lifecycle of the product. This enables a company to design, build, and deliver products and services that meet or exceed their customers’ needs and expectations.”[1]

In addition, Windchill’s core configuration management capabilities have been further enhanced to provide advanced support for configurable products.  Together with new digital mock-up capabilities in Creo® 2.0, these enhancements in Windchill contribute to PTC’s AnyBOM™ Assembly technology vision; promising to give teams the power and scalability needed to create, validate and reuse information for modular product architectures. 

PTC is also extending the breadth of product-related content that can be managed in Windchill for retail and consumer product companies.  With a new version of its FlexPLM technology, companies can now reference CAD models managed in a Windchill environment – giving retail product designers much greater visibility and understanding of how to work with products that have both hard and soft goods (e.g. a chair’s frame and fabric).

Know More: Track Compliance, Quality, Cost

In the critical area of compliance, PTC has extended Windchill’s capabilities for tracking and monitoring regulated materials use.  For example, the recent Conflict Minerals legislation passed by the US Government drove the introduction of new management and reporting capabilities to help manufacturers identify and assess the compliance status of products containing the regulated minerals of tantalum, tin, tungsten, and gold and their many derivatives. This allows companies to effectively protect their corporate brands, mitigate risk of non-compliance with government regulations and customer requirements, and avoid possible fines and penalties.

To further assist manufacturers with their quality initiatives, PTC has enhanced how Windchill analyzes the latest product structure information to provide early and accurate insight into product reliability.  For example, critical-to-quality characteristics identified in Creo are automatically communicated to Windchill Quality™ offerings for risk and reliability analysis, associating these characteristics with the test plans and manufacturing controls designed to ensure their quality.  A new Windchill Customer Experience Management™ module provides a highly-structured and automated process flow to trace and respond to customer complaints about product quality.  This enables a company to consistently resolve quality issues in a manner compliant with government regulations or quality management standards.

PTC has also enhanced how companies can accurately track product cost estimates and maintain related historical information by managing and displaying product cost information in multiple currencies.

Get More: Windchill Goes Mobile

With the new release, PTC is introducing a new Windchill Mobile app, giving users instant “anytime, anywhere” access to current product and process information.  Windchill Mobile includes an innovative “shake and break” capability that allows users to explode a product assembly by simply shaking their mobile device to see the internal parts in greater detail.  This helps companies improve worker productivity, regardless of whether they’re on the road, the manufacturing floor, or visiting a customer.  Windchill Mobile is available today to download from the Apple iTunes store for both the iPad and iPhone.  Windchill also now supports Apple users even if they aren’t on a mobile device with support for Mac OS X.

PTC has also simplified the Windchill system administration tools to improve reliability and lower overhead associated with running a Windchill installation.  For example, the new PTC System Monitor continuously checks the Windchill production environment to give administrators greater visibility into system performance, allowing proactive detection of potential bottlenecks before they impact end users, and reducing time to repair.

Finally, Windchill continues to build on the dramatic improvements PTC introduced in its user experience, making great use of graphical information and further simplifying workflows to accelerate tasks.  For example, the new Relationship Explorer allows users to visually navigate between related parts, documents, CAD designs, requirements, and change objects.  This allows users to quickly navigate across product structures to find the information they need.

More information will be shared at PTC’s upcoming annual user event, PlanetPTC Live.

3D CAD Tips

There are three general groups of people who are going to be interested in Active Workspace: those who use Teamcenter, those who’ve thought about adopting Teamcenter, but haven’t made the jump yet, and those who are using competing PLM solutions, who will likely be telling their suppliers “we want something like this.”

Siemens PLM describes Active Workspace as “a personalized environment for accessing the entire PLM ecosystem, which provides all PLM users with the right information at the right time to make the right decisions. Active Workspace delivers high-performance search and visualization capabilities, simple yet powerful collaboration tools, and a groundbreaking user interface. Active Workspace delivers the multi-disciplinary decision support platform that PLM workers need to make smarter decisions and better products.”

So, Active Workspace connects users to the resources (people and information) they need to get their jobs done better.

Siemens PLM Software CEO Chuck Grindstaff puts it this way: “All companies and individuals face the challenge of dealing with information overload due to the increasing speed and volume of data coming from multiple sources. Active Workspace helps companies manage this challenge and significantly enhances decision making by reducing complexity and intelligently presenting PLM information that is accessible for all users… Active Workspace creates an intuitive and personalized 3D graphic interface that significantly enhances the ability of our PLM suite of offerings to deliver knowledge instantly to the right people, at the right place and in the right context to support rapid and intelligent decision making.”

Like I said, it connects users to the resources they need to get their jobs done better.

Joe Barkai, the Practice Director for Product Lifesyle Strategies at IDC, explains it a bit differently: “The constant increase in product complexity creates a need for a strong multi-disciplinary decision support platform that makes information exchange and collaboration simple, intuitive and effective. A dynamic decision support system, like Active Workspace, creates rich technical and business context to enable intelligent, high-fidelity decision making.”

Like I said, it connects users to the resources they need to get their jobs done better.

You might call Active Workspace a “dashboard.” It’s the place where a user will come to at the beginning of their work day. Here are Active Workspace’s major features:

Visualize and Navigate Product Data

• Allow users to easily locate, browse and visualize products in greater detail using intuitive graphical controls.
• New high-performance visualization capabilities allow users to view products in a fraction of the time previously required.
• Intuitively see and understand how data relates to the network of information that supports and defines it, helping users make timely, high-quality decisions.

Compare and Report Product Information

• Easily investigate rich PLM information directly on the 3D product model with color-coded, easy-to-understand, visual reports.
• Create visual reports without the need for training or support from IT.

Configure and Share Contexts

• Save the recipe for decision contexts by utilizing our innovative new shelf.
• Share information with another user or a whole group of users − whether it is a filtered list of search results, a color-coded visual report, or anything else – by dropping it on the shelf.
• Once something is on the shelf, anybody else with access can reference the data, confident that the information is accurate and current.

Dassault Systemes SolidWorks Corp this week announced a new product: SolidWork Plastics.

Actually, it’s not strictly new, and it’s not just one product. SolidWorks Plastics was developed and originally sold by Simpoe, a provider of plastics injection molding simulation software. Dassault entered into an agreement whereby SolidWorks will now sell the software under their banner.

There are two versions of SolidWorks Plastics. The Professional version (US$4,995.00) is for people who design plastic injection molded parts. The Premium version (US$14,995.00) is for mold designers.

If you’ve been using SolidWorks for a few years, you might remember that the 2007 version came with MoldflowXpress, a limited function molding simulation tool that included a generic materials database, part-only analysis, single gate location, and a go/no go result, showing whether a part would fill. MoldflowXpress was what you might call a “good enough to be useful, not good enough to take sales from our more expensive products” tool. Still, it was pretty useful, and nicely integrated into SolidWorks. It became unavailable about the same time SolidWorks’ arch-competitor Autodesk purchased Moldflow. (Imagine that!)

After MoldflowXpress went away, Simpoe was one of the companies that stepped up to the plate, to offer a “gold” partner product for plastics simulation running embedded in SolidWorks.

I’m guessing that users were happy enough with the Simpoe products that Dassault decided to bring them into the fold.

SolidWorks Plastics Professional is quite a bit more capable than MoldflowXpress ever was. It allows parts designers to verify uniform wall thickness (a fundamental best practice of plastics part design), optimize the thickness of features such as reinforcing ribs to avoid sink marks, and predict (and either minimize or eliminate) weld lines. It includes a material database with around 5,000 grades of commercial plastic. It has a very useful set of capabilities for people who design plastic injection molded parts. (And SolidWorks is probably the leading CAD tool for this purpose.) The important thing about SolidWorks Plastics Professional is that it lets parts designers verify manufacturability early in the design process, long before cutting any tool steel. It’s not trivially inexpensive, but compared to the cost of a few trashed molds it’s a bargain.

SolidWorks Plastics Premium is for mold designers. It’s a big-time full-function mold analysis tool, supporting analysis of single-cavity, multi-cavity and family mold layouts, runner balance analysis, and providing a wide range of report plot types for identifying and rectifying problems. It comes with automated report generation capabilities, for sharing results with others. A significant benefit of SolidWorks Plastics Premium, when compared to standalone analysis solutions, is that runs embedded inside of SolidWorks, and uses familiar workflows. Its learning curve should be comparatively easy for experienced SolidWorks users. It should go without saying (but probably doesn’t) that learning curve and usability are exceedingly important, even for people who are domain experts.

While SolidWorks Plastics isn’t technically an entirely new product, now that it’s part of the SolidWorks family, it’ll probably get more attention from resellers, and more awareness among users.  All told, a good thing.

3D CAD Tips

A couple of years ago, Autodesk Labs previewed a product, Project Krypton, which ran inside of 3D CAD programs (including Autodesk Inventor, DS SolidWorks, and PTC Pro/E), and gave real-time feedback on manufacturability, cost, and sustainability of plastic injection molded parts.

Project Krypton has now reappeared, in commercial form, as Autodesk Simulation DFM (Design For Manufacturing.) It works as a plug-in, running in a number of versions of Inventor, Inventor LT, Wildfire, Creo, and SolidWorks. It is available as a subscription benefit for Autodesk Simulation Moldflow Adviser 2013 subscribers, or as a stand-alone product, at US$2,000 for a license to run on any of the supported CAD platforms.

It’s reasonable to argue that engineers who are designing plastic parts should know enough to be able to recognize manufacturability, cost, or sustainability problems. And, if they don’t, they should take the time to learn (for example, by taking a few hours to read any of the many freely available books on the subject, such as General Design Principles for DuPont Engineering Polymers.) Even though that argument is reasonable, it doesn’t recognize human nature. People, even engineers who should know better, don’t always take the time to “read the manual.” Often, it makes sense to build the “manual” into the tools that engineers use every day. Simulation DFM does that, and quite a bit more.

For inexperienced designers, Simulation DFM provides quick feedback to help them avoid rookie mistakes. It’s sort of like an “idiot light” on a car’s dash, that warns you when something is wrong. And while old-hands might say they prefer gauges to idiot lights, experience has shown that idiot lights are useful to experts (even F1 drivers and fighter pilots) for catching their attention, and getting them to actually look at the gauges.

Simulation DFM doesn’t require that users have any background in molding simulation. It uses “green is good, yellow is not so good, and red is bad” indicators to identify potential manufacturing, cost and sustainability issues, showing the source and location of the problem. Any issues that pop-up can be expanded upon, to provide more detail on the exact source of the problem, even showing, for example, mold filling analyses.  The software requires no additional training, and doesn’t require much user input.

The open question with Simulation DFM is “how good is it?” Since it’s based on the Autodesk Moldflow simulation engine, it should be quite good, even for relatively complex parts (though it doesn’t support multi-body parts.) Yet, even if its capabilities were modest, it would still be of value, in either helping beginning designers to learn good design practice, or helping old-hands catch mistakes they might have otherwise missed.

As an engineer, I’ve long had the habit of using the “anything I can see” test to evaluate the usefulness of software. I look around the room, looking at anything I see, and ask myself “would this software have helped the engineers who designed these things?” In this case, as I sit in my office, I can see at least 20 items (without even turning to look behind me), each with multiple injection molded parts, that would have been quicker, easier, and less-expensive to design, had their engineers had access to up-front DFM software, such as Autodesk Simulation DFM.

The most significant benefit of Autodesk Simulation DFM comes not from its detailed capabilities, but rather from its clean integration into the design workflow. A user need not press a button, or take any specific action when designing a plastic part to benefit from it. All they need to do is notice, as they design, whether the software has picked up any obvious red-flags.

That Autodesk decided to make Simulation DFM available for Pro/E, Creo, and SolidWorks (as well as Inventor) shows that rational minds sometimes do prevail: There are untold thousands of PTC and SolidWorks customers who design plastic injection molded parts, and who are unlikely to switch primary CAD tools any time soon. The challenge Autodesk is going to face is in getting Simulation DFM in front of those users (since PTC and SolidWorks sales reps and dealers are not likely to recommend it.) Maybe not so much of a challenge: Many of Autodesk’s existing Moldflow customers are Pro/E and SolidWorks users.

There’s a certain charm to software that does something of great value, but does not impose any extra demands on its users. Autodesk Simulation DFM looks like it may be that kind of product.

3D CAD Tips

The new browser-based access is powered by the Autodesk Inventor Engineer-to-Order Server, which includes the ETO (Intent) Rules Engine and the Inventor Server (for model and drawing generation), as well as web services and server farm management software. Graphic display is via the Autodesk DWF format, for browsers with the Autodesk’s DWF Viewer browser add-on, and via raster graphics otherwise.

The Inventor ETO Server is licensed on a per-server basis, supporting 10 concurrent users. The included server farm management software supports load balancing and scaling. Because the server framework is session-based (i.e., not stateless), system requirements are about the same as for Autodesk Inventor. With big and complex models, you’re going to need to have pretty stout servers.

Autodesk is not currently offering Inventor ETO Server with software-as-a-service (SaaS) licensing, though, from a technical perspective, there doesn’t seem to be anything to prevent this. The software can be run in a virtual machine (VM), and hosted on a cloud service. The applications at http://etosamples.autodesk.com, for example, are running on Amazon EC2 instances.

Applications to be deployed on the Inventor ETO Server are created with the Inventor ETO Series product, using a Visual Studio-based development environment, supporting the Intent language and .NET languages like VB.NET and C#.

While the Intent language has evolved and been modernized for .NET compatibility, and based on feedback from users, its heritage traces back to the mid-1980s, to ICAD, one of the pioneering products in Knowledge Based Engineering (KBE.)

The Intent Rules Engine used by the Inventor ETO Server is powerful enough to implement nearly any sort of engineer-to-order application you could envision. It can be used to capture geometric and configuration knowledge, as well as business rules. Because the Intent Rules Engine provides the capability to create dependencies between designs (objects), it effectively allows the creation of workflows.

Out of the box, Inventor ETO Server has no ready-made integrations with enterprise systems, such as ERP, SCM, CRM, PDM, or even, for that matter, Autodesk’s new PLM 360 product series. This is not to say such integrations are not possible or practical. Autodesk has done integrations, for example, with ERP and CRM systems, either by direct access to the ERP/CRM database (support for Oracle, SQLServer, Access and IBM DB2 is included), by reading a database extract file from the ERP/CRM system, or by reading an XML based export file from the ERP/CRM system.

Autodesk has a number of large implementations of Inventor ETO, and has apparently had some solid successes with the product. Swedish hydraulic press manufacturer, AP&T, for example, notes that Inventor Engineer-to-Order has helped it reduce cost estimate errors on key components from 10% to 1%. Hytrol Conveyor currently uses 800 seats of Inventor ETO (and is likely a good candidate for the new web-deployed version.)

Interestingly, all of the companies referenced in Autodesk’s customer showcase worked with Autodesk Consulting to develop their Inventor ETO applications. This is not a big surprise. The Intent rules engine and language are definitely powerful, but they’re not for dilettantes (or average Inventor users with no programming skills, for that matter.) You can get a sense of this for yourself, by looking at the source code for Autodesk’s Inventor ETO samples.

Web deployment greatly changes the reach, and the economics, of Inventor ETO. Rather than deploying their Inventor ETO apps on notebook computers carried by salespeople, companies can deploy those same apps on the web, and make them available to their customers, worldwide, 24 hours a day. On a per-licensed-user basis, Inventor ETO is more expensive to deploy over the web than on notebook computers—but, when you account for actual utilization of the software by concurrent users, it’s likely far less expensive.

The actual licensing cost of Inventor ETO is probably only a minor part of the total cost of an implementation, when the cost to develop and deploy applications is factored in. The decision of whether to acquire Inventor ETO probably requires some careful analysis. If you are already an Inventor shop, you have a significant sales volume in configure-to-order or engineer-to-order products, and you have a commitment for enough budget, resources, and time to do the implementation right, you’re probably on the right track.

3D CAD Tips

Why so slow?  Because Creo was recalculating the blend on the fly, as I was dragging.  Since the blend was in the middle of the feature tree, with a bunch of other dependent geometry, each time I moved the cursor, it had to do a very time consuming recalculation.  The right way of resizing the blend would have been to click on the blend radius text, and type in a new value.  Presto… the blend is resized exactly as I wished.  Alternatively, I could have used Creo’s flexible modeling tools, which would have recalculated the blend more quickly (though, when I tried to interactively drag the blend radius using flexible modeling, I still found the dynamic response to be unsatisfying.)

Is there a way to fix the problem I’ve described?  Yes.  Were I moving a boss across a surface that forced topological changes, Creo would have switched to a simplified representation of the boss, rather than recalculating it accurately on the fly.  So, Creo does know how to adjust it’s dynamic response depending on the needs of the situation.  It just doesn’t do it with blends.

The point of talking about this isn’t to beat up PTC. Other CAD vendors have similar problems. Creo is a very powerful product, and expert users can make it sing.  But put a user with a black thumb in front of it, and they’ll often do things that will bring it to its knees.

If PTC were building Creo expressly to satisfy expert users, the kind of experience I’ve just described wouldn’t be an issue. Expert users are smart enough not to do dumb things.  Yet, PTC is going to increasingly find that its products are used by normal folks (not Pro/E gurus), who are less likely to understand the program’s nuances, and who are less likely to be accepting of its quirkiness.  It’s important to get the little details right, so that all users, and not just the experts, can get the most out of their CAD programs.
