There are a number of simulation/analysis software products available for conducting motion and FEA studies. However, the ability to conduct them both, as well as optimizing assemblies is a tall order, especially for mere mortals and non-CAE specialists. With a relatively short learning curve, for this evaluation SimWise 4D proved its mettle for handling motion, FEA, and optimization in one comprehensive package.
What is known today as SimWise 4D began when Design Simulation Technologies (DST) acquired a license from MSC Software Corp. to the MSC.visualNastran 4D (vn4D) product. That software traces its roots to the Working Model 3D product developed by Knowledge Revolution, which was acquired by MSC in 1999, extended to include FEA capabilities, and renamed Working Model 4D.

Although still a few months away, there are a couple of important conferences that will be co-located this year — Collaboration & Interoperability Congress (CIC) and NAFEMS Americas Congress.
NAFEMS and Longview Advisors just announced plans to co-locate the NAFEMS 2014 Americas Conference and the Collaboration & Interoperability Congress (CIC) in Colorado Springs, CO, running May 28-30, 2014..
The central theme of the co-located events is, “Driving Product Development with Collaboration, Simulation, and Integration.” Read the rest of A Tale of Two Upcoming Conferences: CIC & NAFEMS

The MCAD industry, like in recent years past, had many interesting and significant events that took place in 2013. Below are just some of the highlights that we noted for the year.
It wasn’t all that long ago that an MCAD executive referred to the cloud as “mere vapor,” but that is rapidly changing as real engineering applications become available.
In 2013, the cloud began to transition from just a giant storage device to a true platform for running applications as varied as conceptual design to simulation/analysis to rendering.

Last week we were at the Venetian in Las Vegas for what has to be the biggest spectacle in the CAD business — Autodesk University. While other cities could handle the crowd and serve as venues for AU, Las Vegas has been the destination for the annual event for a long time. Vegas is big, bold, easy to get to, and just a lot of fun to be around, even if you’re not into the “Vegas Lifestyle” — gambling, smoking, etc.
AU takes place at an odd time of year because it immediately follows Thanksgiving and is about four to five months prior to the new versions of Autodesk products being released. That said, though, there are always interesting product announcements made at AU.

Over the years, and with considerable interest, we have observed the ongoing consolidation of the technical/engineering software industry, and it continues unabated today. The consolidation occurs primarily through mergers and acquisitions, whether in whole or in part, but consolidation marches on.
We’ve witnessed consolidation in CAD, CAE, and more recently, CAM, and Autodesk has been a major participant in this consolidation. 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 significant, but relatively small step in CAM), and just last week announced its intention to acquire Delcam (a relatively giant leap in CAM).

Virtually since its inception, the CAD/CAM industry has always had its proponents, detractors, champions, pundits, and naysayers, and this diverse group of industry watchers continues to flourish today.
One of the most heated and opinionated debates that I’ve seen in quite some time came when HSMWorks was acquired by Autodesk a little over a year ago. Rumors circulated that HSMWorks was toast because Autodesk was going to kill it, owing to the fact at the time that the vast majority of HSMWorks CAM customers were also using it as an integration with SolidWorks. Well, as often happens, the rumors turned out to not exactly be as disastarous as claimed (or hoped for).

For many years, all of the major CAD vendors have been stressing the importance of managing the design and manufacturing data created using their software. Surprisingly though, still relatively few design and manufacturing companies, especially SMBs, have a formal PDM system of any type in place beyond Windows Explorer or Excel. Some of the reasons we hear for PDM not being employed include the perceptions (and experiences) that PDM is time consuming and expensive to implement.
While most SMBs have made the transition from 2D to 3D, many are finally exploring how to manage the mountains of CAD and associated product development and project data. These companies are seeking solutions that are more capable and scalable than just files, folders, Excel spreadsheets, and Windows Explorer.

While 3D printing gets a lot of attention on the output side of the design process, going from digital to physical; just as important is the converse, going physical to digital, also known as 3D scanning. Like 3D printers, 3D scanners vary in object capture quality (resolution), and associated cost — ranging from a few hundred to tens of thousands of dollars. 3D scanners are also being used for a growing number of applications, including big-ticket industries, such as automotive and aerospace.
The automotive industry has been particularly fertile ground for 3D scanning with applications ranging from reverse engineering to inspection. I recently came across an interesting automotive 3D scanning application using Artec scanners.

Mitsubishi Agricultural Machinery (MAM), part of Mitsubishi Heavy Industry Group, designs, manufactures and sells agricultural machinery. To better meet the needs of a rapidly changing market, Mitsubishi adopted a strategy known as concurrent engineering, using Lattice Technology’s advanced 3D data format called XVL.
Concurrent engineering is a workflow method that promotes a parallel tasks. For example, job functions such as design engineering and manufacturing engineering are integrated, which allows workers to reduce the time needed to bring new products to market.
