@Beth: Throughout the design process things constantly change. Sometimes, even after production has begun. Typically, until the client or a VP says it's perfect, things are in flux.
PLM does not allow for going back to a previous version. You're replacing the last version with the newest one in the system. When management wants to go back to a previous version, it's no longer there. You have to hope that the designer kept a copy in their files and can reload it.
I guess I'm still confused. Wouldn't those changes to the 3D sketches or models be maintained in a PDM or PLM system using the inherent verison control capabilities to ensure everyone is using the latest version? Or are you talking about more conceptual designs prior to actually having a formal 3D CAD model?
@Beth: Maybe my comment wasn't clear to you. It's not about "keeping track of changes". As a designer, I have to create CADs (or 3D sketches). When management asks to see a tweak or change, it ranges from a few minutes to a several hours of work. If I save over the latest version and management wants to "go back", I've created more work for myself. If I save duplicates, I'm using a lot of space on the server (that's where IT comes in).
I used excel as a tracking tool before PLM. It worked well. I've helped develop custom PLM systems for companies over the years and still work as a UX Design consultant for up and coming companies. PLM systems are great for production but only marginally helpful for creatives.
My point is that having a system that can store, maybe, up to 3 versions, without crashing the serving or weighing down the cloud, would be great. Designers would appreciate it.
@NadineJ: The pain point I think you're describing is change management around engineering changes--a common and tricky thorn in the side of all engineering teams, now and in the past. Product Data Management (PDM) and PLM systems were born, originally, out of the need to maintain a central repository of engineering data (and keep track of changes), but they are admittedly often complex, big, and expensive systems--well beyond reach of many shops. Excel spreadsheets have been another stable for managing the changes, but clearly not able to do so in any kind of automated and centralized fashion.
Products like Sunglass and other Web-generation-based collaboration platforms are taking on this problem again and attempting to solve it in a much more streamlined and simpler fashion. Perhaps it's time to get your IT group or your engineering management to revisit the problem now that the technology is bit less onerous.
This is a nice evolution. I'd welcome any opportunity to work with it. I'd like to see the other big problem in the design process addressed. I call it go-back-itis. I can spend hours on a change (or two) only to have the decision makers want to "go-back" to the original.
Of course, I save every version. And, I'm always friendly with IT to make sure I have the amount of space I need in order to keep saving every version, just in case.
Beth, I have noticed many "innovations" in the design engineering space that follow developments in the software engineering field from many years ago. That makes sense for a couple of reasons. Software, since it has no real "manufacturing" process is a bit different. Second, software is appearing in the products, and even for physical objects, in the design flow of the products. This use of a Git like distributed repository is a natural, and good, evolution.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
