Fundamental to any PLM system is the idea of Access Control and data security. Only authorized personnel can access a PLM system and view or manipulate its contents. This is controlled via a login procedure that includes a user password. Personnel are added to the list of authorized users by the PLM administrator after someone has approved of their specific access rights.

Once access has been granted to users, it must then be determined what operations they can carry out on the PLM system. The simplest (and default) security model which allows all users to carry out any operation is very undesirable and could lead to actions that can destroy or leak vital data.

This scenario requires the development of a Security model which determines which user can carry out which operations. Security models are normally based on two concepts:

  1. Roles
  2. Organizations

A role in the database would define what the user who is assigned that role is allowed to do. Typical roles are as follows:

  1. Viewer – this role would be allowed to view data but not make any alterations or modifications
  2. Team Member – this role would be allowed to alter and update a limited subset of the data along with being able to carry out certain operations (e.g. initiate a workflow)
  3. Team Leader – this role would be able to do everything that a Team Member could do along with the ability to operate on a larger subset of data and carry out more operations (e.g. progress a workflow, change ownership)
  4. Approver – this role would be able to approve certain operations on the data (e.g. approve a release of information)
  5. Database Admin – normally limited to a handful of technically qualified people

Once roles in a database have been defined, the organizations are put in place. These normally mirror actual organizational structure, although this is not a necessity. Organizations in a PLM system usually work on specific projects or programs. Once the organization is defined, users are allocated to various organizations and are assigned specific roles.

The final result can be represented in a table as follows:

Within Organization Outside Organization
User Role View Modify Approve View Modify  
John Doe Team Leader Y Y N Y N
Paul Revere Team Member Y Y N N N
David Earp Approver Y N Y Y N

So how is security set up in your PLM system? Are all the security capabilities been used to ensure that no intellectual property is destroyed or leaked?

People are wondering about their workflows now that Product product-design-collection-badge-256Design Suite and Factory Design Suite have been combined into the new “Product Design Collection.” Many of my customer visits in the last three weeks have included the same question: “How is upgrading to Product Design Collection going to affect us?” All of my customer visits the last three weeks were also factory layout users. They have moved from AutoCAD to Factory Design Suite, or FDS. Having made the transition once already, they find themselves faced with the same task: move again.

The discontinuation of FDS and the new subscription model by Autodesk can be daunting for managers and IT departments – not to mention hardware requirements, OS support, developing new workflows, and retraining users. It’s no wonder that some of our customers feel the best course of action is to do nothing for right now.

In actuality, the best strategy at this point is to get informed. Establish three basic realities for your company.

  • What operating system will my company be running in 2017, and on what hardware?
  • What will be the data requirements for transferring files between customers and suppliers 24 months from now?
  • What new technologies and standards will come into play, like 3D Laser Scanning, BIM requirements, cloud access, mobility, licensing models, industry requirements such as energy savings. The list can go on depending on your work environment.

Take back control: develop a three-year plan. It’s actually not as unnerving as many people think.

  • Take a look at Autodesk’s Product Design Collection and what’s included here.
  • Understand the difference between a perpetual license and a subscription
  • Get help from the people who live it: an Autodesk reseller like Tata Technologies. We recently ran a webinar for our Autodesk customers explaining the transition from Suites to PDS, and have since made it available to the general public in the i GET IT Live archives. CLICK HERE TO WATCH OUR PRODUCT DESIGN COLLECTION WEBINAR.

Getting someone like us involved to help clear things up is not the only way to avoid feeling alone or overwhelmed; there are great websites to get information. One of them is the Autodesk Community. I use it a lot, especially lately because of all the changes.

GOOD LUCK, EVERYONE! Please do not hesitate to call us at 877-668-8282.

Back in the day…

There it was, one of the first internet communities, Usenet, about to undergo a sea-change unlike any it had seen before. It was 1993, September, a month that would never end.

IT - Ethernet Cable outletIt started much like the years had before; an influx of new people coming into the universities, getting online for the first time. The community absorbed them in much the same manner as they had in the past. These first-timers were indoctrinated with the well-established etiquette and protocols that were required to thrive in this brave new world.

It seems archaic now, but back then, in the “before times”, there was no way for mass discussion; social media had not yet been born.

The plot twist

And then it happened. AOL, then a name synonymous with the internet, decided to grant access to Usenet for all of its customers. Picture the mobs that gather outside department stores the morning after Thanksgiving: the unlocking of the door let loose a mass of people that overwhelmed the community. There were just not enough graceful souls able to help coach these new users in “civilized” net behavior. Social norms were thrashed; standards went out the window. It was the equivalent of the wild, wild west. In a word, it was chaos.

Future looking

Misc-Walking-peopleNow think of how you on-board new designers or engineers. You show them who’s helpful and who to avoid. You show them around, pointing out places of interest, teach them company standards, design methodologies, workflow processes, etc. Over the coming decade (to be exact, 2014 through 2024), according to stats provided by the Bureau of Labor Statistics (BLS), the Architecture and Engineering field will grow an average of 3.4%, or about 710,000 jobs.

The biggest (projected) job gainers:

  • Civil – 106,700
  • Mechanical – 102,500
  • Industrial – 72,800
  • Electrical – 41,100

Manufacturing - SuspensionCouple this with the BLS projection of labor force participation over the same time period where we’ll see a 1:1.3 ratio of people leaving the work force to people entering. That will be a lot of churn, meaning a lot of people to on-board. The products will be ever more complicated, and the enabling technology will be as well. Technology is cited as one of the reasons the field isn’t growing as fast as other areas.  The productivity gains in PLM are making companies more efficient, even as the complexity grows.

Conclusion

Business - Chess pawn inverseCompanies will need a strategy for managing changes in their employee base as well as the technology evolution. We offer a series of benchmarking and analysis services called PLM Analytics, and there is one specifically aimed at this issue called PLM Support. Let us know if we can help solve your Eternal September.

Our SIMULIA user community has been using the conventional analysis and portfolio tokens for a while now. These tokens are primarily used to access the Abaqus CAE pre-processor, Abaqus solver, and the Abaqus viewer. The analysis configuration offers Abaqus solver licenses in the form of tokens, and Abaqus CAE as well as Abaqus viewer as interactive seats. The portfolio configuration offers all three components of Abaqus, i.e. the solver itself, Abaqus CAE as well as Abaqus viewer as tokens.

                                                                                                                                                      IS SIMULIA = only ABAQUS!

The new equation has been EXTENDED

                                                                                                                                   SIMULIA = ABAQUS + ISIGHT + TOSCA + FESAFE

The overall simulation offerings from Dassault Systèmes go way beyond Abaqus finite element simulations. The functionalities now include process automation, parametric optimizations, topology optimization, fatigue estimation, and many more. And starting from Abaqus release 6.13-2, all these additional capabilities are included in a single licensing scheme called extended tokens. Here is an overview of these additional SIMULIA products.extended-products

When I first started in the Design and Engineering field, CAD was used primarily by large OEMs and some large suppliers. Most companies’ design work was done on drafting boards with vellum and pencils, or Mylar and ink.

paper

As the technology evolved, CAD became more affordable, and increasingly necessary if one wanted to do business with certain OEMs. But while the design work was being done in CAD, the official documents were still paper – actual paper, created in CAD, printed, signed off by hand and distributed through the purchasing departments.

2Dmaster

Eventually the paper gave way to PDF files for distribution, at least from the OEM; most companies still used paper (some still do!) internally to manufacture and inspect their products. They still create, release, and distribute 2D drawings and balloon the drawings for inspection purposes.

3d_process_current

Technology has reached the point where a 2D drawing is really no longer necessary for the manufacture of a part or assembly, yet many companies still create them, even if the OEM does not provide one. Typically, the 3D model is used for fabrication, unless it is being done by hand. The creation, release, storage, and distribution of 2D drawings is huge. I am sure if companies actually looked at what it is costing them they would be shocked.

Some OEMs and other companies have an electronic way to handle the storage and distribution portion which is huge but the creation unless automated is still quite costly. Then there is the interpretation of the 2D drawings which can lead to quality problems, which we know is very costly.
There is a better way. […]

Tangent Select1Autodesk Inventor now includes a new selection filter.  It can be accessed the same way as many of the other selection filters using the “right-click” Tangent Select3menu in Inventor.  Let’s look at an example and the associated steps and results:

  1. Set “Faces and Edges” as your selection filter.  This is typically the default while editing individual components.
  2. Select a face, right click, and pick “Select Tangencies.”
  3. Perform an operation (such as changing color) to all the faces at the same time.

 

Use the selection set of tangent faces to:

  • Delete the selection set with Delete Faces.
  • Assign an appearance to the selection set.
  • Add or remove thickness to faces, or create an offset surface from a part face with the Thicken/Offset command.
  • Copy a set of faces from one component to another (handy for tooling development)

The “Select Tangencies” option can also be used to select a continuous set of tangent edges on a component.

Use the selection set of tangent edges to:

  • Fillet or chamfer the preselected edges.
  • Review or check for tangency conditions or closed loops.

You have probably heard about Teamcenter. You know it is used extensively at the major OEMs. But what does it actually do? How is it made? This article will explain, from the very beginning, what Teamcenter is and how it is put together.

Teamcenter is a Product Lifecycle Management (PLM) platform and is primarily designed to support the design and development of products that subsequently get manufactured. Siemens PLM Software gives a single-picture representation of Teamcenter as follows:

Teamcenter

Firstly, Teamcenter is a platform, meaning that it houses multiple capabilities (apps) in a single seamless piece of software. A user logs into one interface and is able to access all the installed and licensed capabilities of their Teamcenter from there. The platform is based on a database, allowing for storage and indexing of data.

Secondly, the platform is scalable to suit the requirements of each organization using the technology. In fact, Siemens PLM Software have categorized the apps into three groups: Start, initial deployment; Extend, increase functionality; and Transform, move to advanced capabilities.

Thirdly, Teamcenter grew out of the necessity to store and maintain all the digital data generated during product development after widespread adoption of CAD applications. It now has extensive capabilities beyond that.

Let us look at the three groups and define at a high level each one of the apps: […]

So your company has embarked on the PLM journey. Strategy is agreed, budget is approved, the preliminary plan for execution is in place and Return on Investment has been computed.

The next step in the process is choosing a software suite and an associated vendor. Unfortunately, the nature of software is such that one cannot mix and match programs or modules to suit specific requirements; the major vendors design their solutions is such a way that organizations are locked into a specific monolithic offering. The choice of vendor then has long term ramifications and, on the face of it appears to be a momentous decision.

So, how does one choose a PLM technology vendor? For the purposes of answering, let us submit two potential techniques:

  1. Undertake a comprehensive study to evaluate the merits of each vendors solution against requirements, conduct benchmarks and produce recommendations (The bake off)
  2. Meet in the main boardroom of the company, ensure attendance of auditors and all interested parties and toss a coin to decide which vendor to choose (The coin toss)

Before debating the merits and demerits of each technique, it is instructive to outline a methodology for the bake off option. The high level steps required to conduct a study are as follows:

  1. Outline business imperatives and goals (e.g. global engineering)
  2. Identify the PLM processes that have to be put in place or facilitated to meet these goals (e.g. extended design reviews)
  3. Create use cases to illustrate the processes (e.g. ability to load complete product into webex session and have geographically dispersed teams critique)
  4. Evaluate each technology against the use case and score its capability to support the use case (e.g. how long does it take to load a product into a review session)
  5. Total up all the scores and make a recommendation.

Clearly the bake off would be the conventional business approach. It offers the advantages of rigor, objectivity and a comprehensive approach. By following the evaluation methodology, an organization is guaranteed of having a technology that supports its needs.

So why even consider the coin toss? Any business person worth his salt would recoil at the thought of employing such a sloppy and unscientific method. But before dismissing this out of hand, consider a few items. Firstly, technology changes at an alarming pace and what is good today in one vendors solution will be outpaced by next year’s release. Secondly, the tough part of PLM implementations is managing organizational change and this has nothing to do with technology. Thirdly, agonizing over decisions is probably worse than making a snap decision – fortune favors the bold.

So consider the coin toss or a at least a compressed bake off; it can certainly save time and maybe allow an organization to leap ahead of its competition.
