3DCIC 2014: Driving Product Development with Collaboration, Simulation, and Integration

 
June 2nd, 2014 by Jeff Rowe

Last week I attended the 11th 3D Collaboration & Interoperability Congress (3DCIC) in Colorado Springs, CO as one of the event’s media sponsors. The three-day event focused on promoting and improving collaboration and data interoperability throughout the product lifecycle — from concept through retirement.

For the first time this year, NAFEMS (the international association of the engineering modeling, analysis, and simulation community) held its fourth NAFEMS Americas conference, co-locating and coinciding with 3DCIC 2014.

CIC distinguishes itself by being a vendor-neutral event that addresses collaboration and interoperability across several industries for product development, simulation/analysis, manufacturing, and overall business purposes.

The theme of 3DCIC 2014, which attracted more than 250 attendees, was “Driving Product Development with Collaboration, Simulation, and Integration.” Progressive organizations have realized that the integration of design, analysis/simulation, manufacturing, downstream processes, and the supply chain are vital components for keeping them competitive and profitable. It’s really the underlying basis of the sought-after nirvana of PLM. This was also the focus of 3DCIC 2014 – the notion that collaboration is totally dependent on interoperability between disparate groups and processes.

Although it was challenging to carve away time during the conference, I was able to sit down with David Prawel, Founder and President of Longview Advisors and 3DCIC for his take on the conference, as well as the current state of collaboration and interoperability.

Software Evaluation: SolidWorks & SolidWorks Enterprise PDM

 
May 29th, 2014 by Jeff Rowe

Editor’s Note: This is the second installment of a series of four evaluation articles of CAD/PDM systems for SMBs.

Overview

SolidWorks Enterprise PDM is one of two PDM products offered by DS SolidWorks and is a separate purchase. SolidWorks Workgroup PDM is available integrated inside of SolidWorks Premium and Professional.

Data cards are crucial elements for managing design data with EPDM because they contain metadata about the files, folders, items, and templates in the vault database. Data card information is stored centrally, so users can search and locate information about files, folders, items, and templates without needing local copies.

By adding controls such as text fields, list boxes, check boxes, and tabs, data cards are used for managing the design process.

Book Review: Wohlers Report 2014

 
May 22nd, 2014 by Jeff Rowe

An organization that we know quite well, Wohlers Associates, Inc., recently released the Wohlers Report 2014, the company’s annual detailed analysis of additive manufacturing (AM) and 3D printing worldwide. According to the Report, in 2014, interest in 3D printing reached an unprecedented level and exceeded the $3 billion milestone. The phenomenal attention to AM began in 2012, and it was sudden. As Greg Morris of GE Aviation said, “It was like someone flipped a switch.” Governments, major corporations, investors, and the mainstream media developed an insatiable appetite for additive manufacturing, and it occurred quickly.

Wohlers Report 2014

As it has from the beginning, Wohlers Report 2014 covers virtually every aspect of additive manufacturing, including its history, applications, underlying technologies, processes, manufacturers, and materials. It documents significant developments that have occurred in the past year, R&D and collaboration activities in government, academia, industry, and summarizes the worldwide state of the industry. This edition is the report’s 19th consecutive year of publication.

Wohlers Associates believes the industry will continue strong growth over the next several years. It will be fueled by sales of under $5,000 “personal” 3D printers, as well as the expanded use of the technology for the production of parts, especially metal, that go into final products. “The industry is experiencing change that we have not seen in 20+ years of tracking it,” stated Tim Caffrey, senior consultant at the company and one of two principal authors of the new report. He added, “What’s most exciting is that we have barely scratched the surface of what’s possible.”

CAD/PDM Software Evaluation: Autodesk Inventor/Vault Professional

 
May 16th, 2014 by Jeff Rowe

Editor’s Note: This is the first installment of a series of four evaluation articles of CAD/PDM systems for SMBs.

Overview

Autodesk Vault Profession is one of three levels available from the company. Also available are Vault Basic and Vault Workgroup.

Vault Professional is a standalone application providing access to vault data. Integrated add-in clients for CAD and non-CAD applications are used to manage data. When working on files managed by any vault-type system, it is important to note that copies of files that are stored in the vault are checked out. Files are never directly edited in the vault; these files are read-only until they are checked out. In effect, copies of files are checked out of the vault for editing. In a vaulting scheme, a file can be checked out only by one user at a time. Changes made to checked out files are sent back to the server when a file is checked in.

COFES 2014: Focuses on the Year 2020 and 20/20 Vision

 
May 7th, 2014 by Jeff Rowe

I just returned from the Arizona desert and COFES 2014. The annual event (in its fifteenth year), also known as the Congress on the Future of Engineering Software (COFES), is more than just an event featuring technology as its central theme for technology’s sake. It’s actually more of an immersive educational experience that brings together many of the best minds in the technical realms of engineering software, hardware, education, and architecture, among many others.

COFES is recognized as a think-tank event that gathers vendors, users, press, and analysts together to discuss the many important issues facing both customers and providers of diverse technologies. The three-day event provides a relaxed and informal atmosphere designed to foster genuine conversation.

According to Cyon Research, the organization behind it, COFES is:

  • A think tank where great minds come together to discuss best practices and to share ideas for managing change
  • A technology summit that promotes discussion and problem-solving among industry thought-leaders, analysts and customers
  • A business event that delivers practical strategies for achieving financial success in the engineering and design technology sector
  • An informal environment where business leaders and technology providers can meet to identify and address key industry issues and challenges

Having been to a few COFES events myself, it is certainly those things, but also a lot more.

The theme for COFES 2014 was “Correcting 2020 Vision,” that forces our attention to look further down the road to a six-year horizon. Many of the discussions centered on the non-linear nature of the future beyond a two-year horizon. The stated goal at COFES 2014 was to help attendees achieve this clearer vision – one that better reflects the business realities we will all face by 2020.

Until the second day of the conference, I couldn’t discern if the 2020 reference was just the year and/or a reference to visual acuity. As it turns out, it was some of both. Although no one can predict the future with absolute certainty, the year 2020 provides a good vision and timeline for what might be on the horizon. The trick is now that the horizon has been set, how do we build the vision?

The format of the Congress encourages active (and sometimes very spirited) exchanges and interactions on everything ranging from PLM to 3D printing to STEM to coding to engineering search engines. The keys are the discussions, dialogs between individuals and not just corporate entities. Discussions take place at all meals, around the pool, outdoors between formal sessions, and around moderated roundtables. Companies, some you’ve heard of and some you haven’t, sponsor briefings in dedicated technology suites. These provide a good opportunity to learn what new and established companies are planning. In any case, all of the discussions point to the value of disagreement, diversity, and respect, as well as rethinking rejected ideas. Read the rest of this entry »

ANSYS Acquires SpaceClaim: May the Force(s) Be With Them

 
May 1st, 2014 by Jeff Rowe

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. Read the rest of this entry »

Autodesk Keeps CAM Door Open and Re-Certifies GibbsCAM

 
April 23rd, 2014 by Jeff Rowe

Over the course of the past year, Autodesk has gotten heavily involved with the CAM side of product development.

As a case in point, relatively recently, Autodesk has made it clear that it intends to become a major force in CAM to round out its Digital Prototyping philosophy that also includes design and simulation. As examples to this CAM commitment, in the past year or so it has acquired HSMWorks (a relatively small step in CAM), and more recently announced its intention to acquire Delcam (a relatively giant leap in CAM).

It was really big news when, Autodesk announced its intention to acquire Delcam, one of the world’s leading suppliers of advanced software for manufacturing. The companies offer complementary ranges of software, with Autodesk’s programs for design (CAD) and engineering (CAE) able to be combined with Delcam’s strengths in manufacturing (CAM).

On completion of the acquisition, Delcam will become a subsidiary of Autodesk. It will maintain its focus on continued growth of its market share in the manufacturing sector, counting on added strength that will come from becoming part of a larger organization.

Both Delcam and Autodesk invest heavily in product development, and this will likely continue after the acquisition, as there is likely to be little overlap and duplication of effort.

Delcam is a publicly traded company and will be purchased with cash that Autodesk has stashed outside the U.S., keeping it there most likely for advantageous tax purposes and for opportunities for transactions like this one.

GibbsCAM and Autodesk Inventor Interoperability

Cimatron Limited, a developer of integrated CAD/CAM software for toolmaking and manufacturing, announced this week that its GibbsCAM software has been certified for Autodesk Inventor 2015 under the Autodesk Certified Apps Program. This marks the fourteenth consecutive year that GibbsCAM has been certified under the program.

GibbsCAM directly opens Autodesk Inventor part models, allowing CNC programmers and machinists to program machine tools from the models, extending cost reduction and efficiency through the programming and machining processes. GibbsCAM provides integration with Autodesk Inventor, by directly reading Autodesk Inventor IPT (part model) files, preserving all color information, features and attributes assigned within Inventor to provide continuity in recognizing and communicating part and feature attributes. Alternatively, with the GibbsCAM Autodesk Inventor Add-in, Inventor users can transfer files directly into GibbsCAM with the “Transfer to GibbsCAM” menu option of Inventor software running on the same workstation. Once machining processes are defined in GibbsCAM, they are automatically updated when the Inventor model is revised.

“We are gratified for our continuing partnership with Autodesk and for Autodesk’s recognition of GibbsCAM interoperability with Autodesk Inventor,” said Robb Weinstein, Senior Vice President of Sales and Strategic Planning of Gibbs and Associates, a Cimatron subsidiary. “Our commitment to joint customers around the world remains unchanged, despite changing marketplace dynamics, as we continue to optimize the CNC-programming power and flexibility GibbsCAM provides Autodesk users.”

“We are very pleased to have Gibbs and Associates affirm their continuing dedication to interoperability with Autodesk Inventor through Inventor certification for GibbsCAM,” said Carl White, Senior  Director, Manufacturing Engineering, Autodesk. “Having companies like Gibbs and Associates as partners is highly beneficial to our manufacturing customers.”

In 2008, Gibbs and Associates merged with Cimatron Ltd., and is now operating as a wholly owned subsidiary.

The GibbsCAM product line supports 2- through 5-axis milling, turning, mill/turning, multi-task simultaneous machining and wire-EDM.  GibbsCAM also provides fully integrated manufacturing modeling capabilities that include 2D, 2.5D, 3D wireframe, surface, and solid modeling. GibbsCAM is either offered or endorsed by a number of leading worldwide control and machine tool manufacturers, including GE Fanuc, Infimatic, Siemens, Doosan Infracore, DMG MORI, Haas, Index, MAG, Mazak, Mitsubishi, Okuma, and Tornos.

Jury Awards Millions For Simulation Software Misappropriation (and Misunderstanding?)

 
April 17th, 2014 by Jeff Rowe

Earlier this week, MSC Software Corp. announced that a jury in the United States District Court for the Eastern District of Michigan found that Altair Engineering willfully and maliciously took MSC Software trade secrets (from Adams simulation software) to use in its MotionSolve product. In other words, the ruling spells out that Altair Engineering knowingly took MSC Software trade secrets with malicious intent.

Keep in mind, though, that this award was no slam-dunk, as the suit was first filed in July 2007 as MSC Software Corp. versus Altair Engineering Inc. The six-week trial ended with two days of jury deliberation.

The jury awarded MSC Software $26.1 million for misappropriation of trade secrets and breach of confidentiality agreements by Altair and two former MSC employees who are currently executives at Altair.

Jurors found that Altair had misappropriated some source code as well as concepts or processes that are used to write the code from MSC, and that the employees had also violated one or more non-solicitation, confidentiality, or severance agreements with MSC.

According to the lawsuit, after Altair hired some former MSC Software employees, Altair began developing a software product called MotionSolve that competed directly with MSC’s Adams/Solver.

MSC had previously alleged that at least eight employees had left MSC between 2005 and 2007 and took jobs at Altair. Five of those employee claims were dismissed prior to trial.

SOLIDWORKS Mechanical Conceptual Hits the Market, But Does It Hit the Mark?

 
April 10th, 2014 by Jeff Rowe

With surprisingly relatively little fanfare, DS SOLIDWORKS last week announced the availability of its long-awaited new product, Mechanical Conceptual (MC for short). Dassault Systemes says that MC is the first SOLIDWORKS application on the 3DEXPERIENCE platform — “that embraces the new realities of today’s world of design in the age of experience: it is more social and conceptual and delivers on the promise of ease-of-collaboration among key contributors.” All of this is something I’m still unclear exactly what it is, what it does, and what it means.

I contacted Kishore Boyalakuntla, Director, Product Management, SOLIDWORKS, who is in charge of managing Mechanical Conceptual for some clarification on what the press release announcing the launch lacked.

Mechanical Conceptual was formally introduced a few months ago at SOLIDWORKS World with the following four basic tenets — conceptual, social (collaboration), connected, and instinctive. The conceptual part I understand, because that’s the primary purpose of MC. It also lends itself to collaborative methods because it’s a cloud-based application, as well as instinctive, because it has direct modeling/editing capabilities. The connected part, though, especially to SOLIDWORKS is still a bit of a mystery. Read the rest of this entry »
