Editor’s Note: This is the third installment of a series of four evaluation articles of CAD/PDM systems for SMBs.
Siemens’s Teamcenter Rapid Start is a product data management (PDM) solution that is preconfigured, yet extensible. As a preconfigured deployment option of Teamcenter, it is intended to address the most common PDM needs of SMBs. With its “simplified” installation process, Teamcenter Rapid Start applies preconfigured best practices to common engineering tasks and processes for SMBs.
In a stand-alone environment, all server and all client applications are installed on each machine. In a shared environment, server applications are installed on a single server. Each machine has network access to the server and has only the client applications installed.
The video that follows shows how to get started with Teamcenter Rapid Start PDM, and includes demos on CAD data management, document management, and process management.

Well, another CAD company is snapped up, and the technical software consolidation train continues to roll on. That in itself is not too surprising. What is, though, is that a CAE company has acquired a CAD company.
ANSYS announced earlier today that it has acquired SpaceClaim Corp. for a purchase price of $85 million in cash, plus retention and an adjustment for working capital. The transaction closed on April 30, 2014.
ANSYS SpaceClaim Overview
From the beginning, SpaceClaim said it offered a 3D modeling tool that could be used by more than just CAD experts during the product development process (and this is a key point to the acquisition). According to SpaceClaim, this is made possible because of a process, called “direct modeling,” that differs dramatically from traditional CAD software, which is used by a relatively small percentage of engineers – typically late in the development process, to document the detailed design. While direct modeling itself is not unique, SpaceClaims implementation of it is. (more…)

Over the course of a year I read a lot of books — technical, non-fiction, hardcopy, and digital. Most of them I get through, although there are some I don’t even try to finish, and a few become favorites and are kept for future reading on my bookshelf. I just finished a book entitled Re-Use Your CAD: The Model-Based Handbook by Jennifer Herron. When I saw Handbook in the title, I thought it would be just a dry reference book, but I was pleasantly surprised that it was much more than that — it’s a good learning resource.
First, a little about the author and model-based engineering/model-based design (MBE/MBD).
I’ve known Jennifer for several years as we’ve crossed paths at software conferences. She is the owner of Action Engineering, a company that specializes in the promotion, process development, and standardization of 3D CAD MBE and MBD. She is an expert in multiple CAD packages, which she uses along with her practical design experience to hone standards and processes that optimize the ROI of all CAD systems.
She also offers model-based documentation education seminars, MIL-STD-31000A schema and modeling best practice training, as well as planning consulting services for Model-Based Engineering implementation. Keep in mind as you read the book that based on her experience, she is a stickler for standards, such as ISO, but you realize that’s probably a good thing.
Her company is a consulting firm that transitions government organizations and companies to effectively and efficiently implement Model Based Engineering. With a specialty in training organizations to document and tailor their business practices to be compatible with CAD, PDM and PLM software tools, Action advises companies in: CAD modeling standards and best practice, designer modeling efficiency, CAD configuration management, MBE training, team collaboration and CAD interoperability.
The concept(s) of MBE/MBD have received a lot of attention in the past few years because this approach handles product development using a digital master model, and not just necessarily CAD. All downstream activities can be derived from the master model to develop a product. The MBE/MBD approach replaces puzzling documents and can minimize the need for physical prototypes before an optimized design has been developed. In other words, engineers and designers can simulate and iterate as much as necessary to refine a model while also meeting requirements and adhering to design constraints.
Now on to the book . . .
Reuse Your CAD Handbook
The book is structured in a logical manner for those both new and experienced with MBE/MBD. Throughout, it stresses the importance of standardizing, centralizing, documenting, and reusing a CAD database. It’s written in a CAD-agnostic manner, so its principles can be applied in any CAD environment, regardless of vendor.
A sampling of some of the topics covered in the book include:
- Explanation of the philosophy of designing products using CAD model-based life-cycles
- Implementation guide to model-based commercial (ASME Y14.41), government (MIL-STD-31000A) and company standards
- Model-based benefits, risks, and action plans
- 3D MBD model organizational schema
- 3D MBD model protocols to satisfy the schema CAD agnostically
- Part and assembly modeling best practice
- Mass property implementation methods
- 3D model Data Exchange (DEX) methods
- MBE support infrastructure requirements
- Product data management (PDM) fundamentals and requirements

A good friend of ours at MCADCafe, Jennifer Herron, owner of Action Engineering, a company that specializes in the promotion, process development and standardization of 3D CAD Model-Based Design (MBD) just released a new video on reusing CAD parts.
In the video, Action Engineering calls a catalog part, a part or subassembly used more than once in a family of products. It may be a bearing, motor, bolt or washer. In a 3D model-based environment a catalog part model should be assembled into your organization’s native CAD assembly models and includes accurate geometry (as specified from the supplier), attributes (Material, Color), metadata (Part Number, Description, Supplier) and annotations (Dimensions and GD&T). A single catalog part model is the single authority for each catalog item used in your organization.

Along with about 1,900 attendees, we just returned this week from the 2013 edition of the PTC Live Global conference and exhibition in Anaheim, CA. We saw and heard several interesting things from PTC employees, partners, and customers.
Let’s start off on Day 1. After a short introduction, PTC’s president and CEO, Jim Heppelmann took the stage with the song “Iron Man” by Black Sabbath blasting. What’s that about? The early focus of his address was the focus of not only PTC, but just about every other software vendor – mobility.
This dramatic change of tune comes just a couple of years after Heppelmann derided the notion of software as a service and cloud computing as nothing more than “vapor.” Today, mobility to PTC, according to Heppelmann, consists of products being delivered as a service, with the line blurred between product and service.
Click on this link to view Jim Hepplemann’s keynote address at the PTC Live Global event.
He then introduced the concept of reverse innovation to accommodate different unique requirements for different customers. Interesting concept, but I need to get more details on exactly what this means.
He went on to say that for products in general, value is shifting away from hardware to software, especially embedded software. Increasingly, products are defined, upgraded, and updated via software. Traditional hardware manufacturers are beginning to employ more software engineers than mechanical engineers. As handy as these software innovations might seem, do they offer too many choices and ultimately frustrate customers and drive up costs? The verdict on this remains to be seen, but I tend to say, “yes,” too many choices can be overwhelming, especially for products that are meant to be simple.
What he was getting at, though, is that increasing numbers of CPUs and software mean “smart” products connected to the Internet. In other words, an “Internet of things,” thanks largely to increasing connectivity.
With 10 Creo apps currently available, and although the next release of Creo (3.0) won’t be available until early next year (Q1?), a few hints were given about what it might look like. Think scalability and interoperability – more on that later, though. PTC says that today, one in four Pro/ENGINEER users has upgraded to Creo, but sees adoption rate at 50% uptake by the end of this year. That seems just a bit optimistic, but potentially doable.
I’ve just begun with the highest of highlights about the conference and the future as PTC sees it. Over the few weeks I’ll discuss some of the most significant announcements coming out of PTC’s user conference with regard to new products/technologies, corporate direction, and customers’ reactions. From what I witnessed this week, PTC’s future looks brighter than it has for quite some time.

At the recent International Manufacturing and Technology Show IMTS) in Chicago, ThomasNet.com formally relaunched its free platform for supplier discovery and sourcing of components, equipment, MRO products, raw materials and custom manufacturing services. The new ThomasNet.com offers users an even wider range of content, tools and resources. Engineers, purchasing professionals, and facilities managers can quickly find suppliers, source products, and access CAD models and product news.
For those of you not familiar with it (or old enough) and before going online, the Thomas Register of American Manufacturers, were known as the “big green books” and “Thomas Registry”, a multi-volume directory of industrial product information covering distributors, manufacturers, and service companies within over 60,000 industrial categories. It was first published in 1898 by Harvey Mark Thomas as Hardware and Kindred Trades. The company stopped publishing its print products in 2006 due to declining circulation as Internet searches eroded the products’ usability.
1905 Thomas’ Register of American Manufacturers
Since then, Thomas moved its database online as ThomasNet, published and maintained by Thomas Industrial Network. ThomasNet has expanded to provide not only product and company information, but Online catalogs, computer-aided design (CAD) drawings, news, press releases, forums, and blogs.
After IMTS I spoke with Tom Greco, VP of ThomasNet ThomasNet with one main question: With so much available online, why should I feel compelled to use ThomasNet.com? He said that the one of the most compelling reasons for using the ThomasNet.com platform is Product Search (ps.thomasnet.com) that enables users to find the specific components and products they are looking for.
Thomas’ team of content engineers has aggregated detailed information and line item detail for over 100 million parts from over 30,000 suppliers. Product Search allows users to specify the product they are looking for using groundbreaking taxonomy-powered search and navigation features. Specifiers can find the product that meets their requirements by defining precise product attributes such as applications, materials, dimensions and tolerances.
The new site also makes it easier for buyers to find local suppliers, quality certified suppliers, and companies that meet their supplier diversity requirements. Whether searching for women-owned businesses, an ISO-certified custom manufacturer, or nearby distributors, the new ThomasNet.com makes it easier to hone in on exactly what you need and create a supplier short list.
“We make it our business to understand the challenges our users face when sourcing, and the new ThomasNet.com is designed to address them. Product Search combines semantic search technology with curated content to create an unparalleled sourcing tool,” said ThomasNet’s Greco. “Product Search is a perfect companion to our improved supplier directory and 2D/3D CAD model library.” According to Greco, interestingly, he said that some 80% of product decisions and purchases are made based on the huge volume of CAD drawings that are available.
Greco said that the new ThomasNet.com platform includes a suite of applications, including:
- Supplier Directory – Over 610,000 suppliers including multi-media company profiles
- CAD Library – Millions of downloadable 2D/3D models and drawings from leading industrial product component OEMs
- ThomasNet News – the latest product, company and industry news
- Job BoardJob Board – to help find your first or next job
- Deal of the Day – Big savings on electronics, office supplies and business services
- Purchasing Tools – Free RFQ Event management and Contract management tools
As for the future, Greco said that in the next 12-18 months extensions will be made to Thomas.Net to what exists today, including additional marketing and product services, as well as additional search utilities targeted to solving specific engineering problems. He also said there will be two to three major upgrades to ThomasNet.com in the next 12 months.
Even with all that is available on the Internet, I still consider ThomasNet.com the “go to” application for product and service discovery and sourcing during the product development process.

Wohlers Associates just published Wohlers Report 2012, an in-depth analysis of additive manufacturing (AM) and 3D printing worldwide. This new edition marks the 17th consecutive year of its publication. I can attest that the Report is the most thorough and comprehensive document of its kind.
Wohlers Report 2012 covers all aspects of additive manufacturing, including its history, applications, processes, manufacturers, and materials. It documents pertinent developments in the past year, covers R&D and collaboration activities in government, academia, and industry, and summarizes the state of the industry in countries around the world. It also tracks the extraordinary growth of personal 3D printers—machines priced under $5,000, with the majority in the $1,000 to $2,000 range.
The information is used to track industry growth, provide views and perspective, uncover trends, and offer insight into the future of additive manufacturing. “The 2012 edition is the most ambitious effort in the report’s history,” said Terry Wohlers, president of Wohlers Associates and a principal author of the new report. Major new parts on applications, materials and processes, and front- and back-end considerations were added. The final part of the report concludes withtrends that are expected to shape the future of the technology and industry.
Additive manufacturing is the process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies. Additive manufacturing is used to build physical models, prototypes, patterns, tooling components, and production parts in plastic, metal, and composite materials. AM systems use thin, horizontal cross sections from computer-aided design (CAD) models, 3D-scanning systems, medical scanners, and video games to produce parts that can be difficult or impossible to produce any other way.
The report sells for $495 worldwide and is available in PDF form. The report’s table of contents, as well as additional information on the market and industry, are available at wohlersassociates.com.
I’ve known Terry Wohlers for many years and consider Wohlers Report THE source of timely and comprehensive information for additive manufacturing. I don’t recommend many books, but highly recommend this one for anyone who wants to get accurate in-depth information on AM.

I recently read some encouraging news from CIMdata contained in its soon-to-be-published Version 21 of the CIMdata NC Market Analysis Report. They estimate, that based on end-user payments, the worldwide NC software and related services market grew by 14.4% in 2011. The estimated end-user payments grew from $1.333 billion in 2010 to $1.525 billion in 2011. The market growth rate in 2011 reflects strong overall PLM spending, continuing the recovery from the downturn in the global economy that manifested itself in dramatically higher machine tool sales into the manufacturing industry. Estimates are that worldwide shipments of machine tools increased by 35% from 2010 to 2011, which is directly related to the volume of CAM software employed to drive these tools. CIMdata projects that in 2012 growth in manufacturing will continue and end-user payments for NC software will increase by 12.4% to $1.714 billion.
Since 2002, the NC software market has shown modest but steady growth as global economies generally improved. There has been worldwide growth in the sale of machine tools and manufacturing output; greater emphasis has been placed on the efficient operation of machine tools as manufacturing firms have strengthened their competitive positions, and the overall PLM market, of which CAM software is a component, has continued on a strong growth path during this period. CAM software purchases are related to all of these factors—particularly machine tool sales.
Alan Christman, CIMdata’s Chairman and author of the NC Market Analysis Report said, “2011 was an excellent year for manufacturers and most providers of NC software. Most firms saw good growth in 2011, and CIMdata expects this growth to continue in 2012 and beyond. The continued strength and growing importance of global manufacturing powers like China and other emerging economies should result in increased investment in advanced technologies like CAD, CAM, and other segments of the overall PLM market. We have seen moves documented in the popular press to bring manufacturing back to the US, which will require still more investment in advanced manufacturing technologies to be competitive with economies with lower labor costs. The next few years should continue to be strong for NC and the broader PLM market.”
This is good news for not only the NC software market, because since 2009, when all engineering/technical software sales sucked, most manufacturing software sectors are today experiencing and enjoying a resurgence in sales. So, is engineering software for manufacturing really emerging from the depths of despair of just a couple of years ago? I’d have to say, yes. Not only are sales stronger, but a number of software vendors have socked enough cash away to make a number of notable acquisitions, making them stronger. Sales aren’t like the “old days” yet, but indicators are definitely moving in a positive direction.

I recently attended a web-based company update by way of a quarterly PTC Virtual Corporate Visit. Over 500 people registered for the event that featured Jim Heppelmann, PTC’s President and CEO, as well as a customer, Dave Winter, VP R&D Lifetime Products. This time, though, I’ll focus on what Mr. Heppelmann had to say.
He started off by saying that PTC has a product and service advantage, meaning that PTC vision is being the premier provider of technology solutions that are transforming how products are created and serviced. PTC focuses on product companies and the processes that determine what and how they will create products and where and how those products will be serviced.
What PTC is offering is not just better products and services, but rather, a better way of creating products and services.
To explain what differentiates PTC’s offerings from ERP, Heppelmann said that ERP optimizes operations through operational coordination, while PTC optimizes product strategy (what-if) with strategy coordination during all phases of the product lifecycle with different functions within a manufacturing organization:
-Hardware and software engineering
-Supply chain and manufacturing
-Sales and service

National Instruments (NI) is an interesting company that develops NI LabVIEW software as its flagship product. The company is fortunate to sell its products to a diverse customer base of more than 30,000 different companies worldwide, with no one customer representing more than 3 percent of revenue and no one industry representing more than 15 percent of revenue. Customer base diversity is an especially good thing in the technical software market.
I have followed NI for a number of years and really got interested in the company a few years ago with LabVIEW 8.5 being used alongside SolidWorks. LabVIEW has followed a natural progression in the evolution of the NI product line for designing and prototyping complex systems, including robots, that are becoming increasingly pervasive in the world around us, and not just manufacturing environments anymore.
National Instruments supports the increasing need for simultaneous simulation of mechanical and electrical systems, also known as mechatronics. As I have been saying for several years, there was a time when mechanical systems and products were strictly mechanical, however, the majority of today’s products continue to become more capable, and more complex, involving the integration of mechanical, electrical, and software subsystems.
A more comprehensive way to view mechatronics is the systematic integration of mechanical, electrical, electronics, and embedded firmware (software) components. When all of the various components are combined the result is an electromechanical system. Maybe a better term is functional ecosystem. In this context, mechatronics is characterized by software and electronics controlling electromechanical systems. This description is widely seen in automotive engines and other automotive systems, as well as production machinery and medical equipment.
A continuing trend is that as mechatronics systems get more complex and as functionality demands increase, in many instances software and firmware are replacing or at least supplementing hardware. A benefit of this transition from hardware to the burgeoning emphasis on software is called “postponement,” that is, the ability to include or change major functionality features during the final stages of production via embedded software.
