Mr. McGuire: “I want to say one word to you. Just one word.”

Benjamin: “Yes, sir.”

Mr. McGuire: “Are you listening?”

Benjamin: “Yes, I am.”

Mr. McGuire: “Plastics.”

– The Graduate, 1967

 

Dassault Systemes SolidWorks Corp this week announced a new product: SolidWork Plastics.

Actually, it’s not strictly new, and it’s not just one product. SolidWorks Plastics was developed and originally sold by Simpoe, a provider of plastics injection molding simulation software. Dassault entered into an agreement whereby SolidWorks will now sell the software under their banner.

There are two versions of SolidWorks Plastics. The Professional version (US$4,995.00) is for people who design plastic injection molded parts. The Premium version (US$14,995.00) is for mold designers.

If you’ve been using SolidWorks for a few years, you might remember that the 2007 version came with MoldflowXpress, a limited function molding simulation tool that included a generic materials database, part-only analysis, single gate location, and a go/no go result, showing whether a part would fill. MoldflowXpress was what you might call a “good enough to be useful, not good enough to take sales from our more expensive products” tool. Still, it was pretty useful, and nicely integrated into SolidWorks. It became unavailable about the same time SolidWorks’ arch-competitor Autodesk purchased Moldflow. (Imagine that!)

After MoldflowXpress went away, Simpoe was one of the companies that stepped up to the plate, to offer a “gold” partner product for plastics simulation running embedded in SolidWorks.

I’m guessing that users were happy enough with the Simpoe products that Dassault decided to bring them into the fold.

SolidWorks Plastics Professional is quite a bit more capable than MoldflowXpress ever was. It allows parts designers to verify uniform wall thickness (a fundamental best practice of plastics part design), optimize the thickness of features such as reinforcing ribs to avoid sink marks, and predict (and either minimize or eliminate) weld lines. It includes a material database with around 5,000 grades of commercial plastic. It has a very useful set of capabilities for people who design plastic injection molded parts. (And SolidWorks is probably the leading CAD tool for this purpose.) The important thing about SolidWorks Plastics Professional is that it lets parts designers verify manufacturability early in the design process, long before cutting any tool steel. It’s not trivially inexpensive, but compared to the cost of a few trashed molds it’s a bargain.

SolidWorks Plastics Premium is for mold designers. It’s a big-time full-function mold analysis tool, supporting analysis of single-cavity, multi-cavity and family mold layouts, runner balance analysis, and providing a wide range of report plot types for identifying and rectifying problems. It comes with automated report generation capabilities, for sharing results with others. A significant benefit of SolidWorks Plastics Premium, when compared to standalone analysis solutions, is that runs embedded inside of SolidWorks, and uses familiar workflows. Its learning curve should be comparatively easy for experienced SolidWorks users. It should go without saying (but probably doesn’t) that learning curve and usability are exceedingly important, even for people who are domain experts.

While SolidWorks Plastics isn’t technically an entirely new product, now that it’s part of the SolidWorks family, it’ll probably get more attention from resellers, and more awareness among users.  All told, a good thing.

Autodesk provides real-time DFM for plastic part design

April 3, 2012 By Evan Yares 1 Comment

There’s a lot of benefit to be had by doing manufacturability analysis (DFM, Design for Manufacturing) early in the design process, rather than waiting until later, when design changes are far more expensive.

A couple of years ago, Autodesk Labs previewed a product, Project Krypton, which ran inside of 3D CAD programs (including Autodesk Inventor, DS SolidWorks, and PTC Pro/E), and gave real-time feedback on manufacturability, cost, and sustainability of plastic injection molded parts.


Project Krypton has now reappeared, in commercial form, as Autodesk Simulation DFM (Design For Manufacturing.) It works as a plug-in, running in a number of versions of Inventor, Inventor LT, Wildfire, Creo, and SolidWorks. It is available as a subscription benefit for Autodesk Simulation Moldflow Adviser 2013 subscribers, or as a stand-alone product, at US$2,000 for a license to run on any of the supported CAD platforms.

It’s reasonable to argue that engineers who are designing plastic parts should know enough to be able to recognize manufacturability, cost, or sustainability problems. And, if they don’t, they should take the time to learn (for example, by taking a few hours to read any of the many freely available books on the subject, such as General Design Principles for DuPont Engineering Polymers.) Even though that argument is reasonable, it doesn’t recognize human nature. People, even engineers who should know better, don’t always take the time to “read the manual.” Often, it makes sense to build the “manual” into the tools that engineers use every day. Simulation DFM does that, and quite a bit more.

For inexperienced designers, Simulation DFM provides quick feedback to help them avoid rookie mistakes. It’s sort of like an “idiot light” on a car’s dash, that warns you when something is wrong. And while old-hands might say they prefer gauges to idiot lights, experience has shown that idiot lights are useful to experts (even F1 drivers and fighter pilots) for catching their attention, and getting them to actually look at the gauges.

Simulation DFM doesn’t require that users have any background in molding simulation. It uses “green is good, yellow is not so good, and red is bad” indicators to identify potential manufacturing, cost and sustainability issues, showing the source and location of the problem. Any issues that pop-up can be expanded upon, to provide more detail on the exact source of the problem, even showing, for example, mold filling analyses.  The software requires no additional training, and doesn’t require much user input.

The open question with Simulation DFM is “how good is it?” Since it’s based on the Autodesk Moldflow simulation engine, it should be quite good, even for relatively complex parts (though it doesn’t support multi-body parts.) Yet, even if its capabilities were modest, it would still be of value, in either helping beginning designers to learn good design practice, or helping old-hands catch mistakes they might have otherwise missed.

As an engineer, I’ve long had the habit of using the “anything I can see” test to evaluate the usefulness of software. I look around the room, looking at anything I see, and ask myself “would this software have helped the engineers who designed these things?” In this case, as I sit in my office, I can see at least 20 items (without even turning to look behind me), each with multiple injection molded parts, that would have been quicker, easier, and less-expensive to design, had their engineers had access to up-front DFM software, such as Autodesk Simulation DFM.

The most significant benefit of Autodesk Simulation DFM comes not from its detailed capabilities, but rather from its clean integration into the design workflow. A user need not press a button, or take any specific action when designing a plastic part to benefit from it. All they need to do is notice, as they design, whether the software has picked up any obvious red-flags.

That Autodesk decided to make Simulation DFM available for Pro/E, Creo, and SolidWorks (as well as Inventor) shows that rational minds sometimes do prevail: There are untold thousands of PTC and SolidWorks customers who design plastic injection molded parts, and who are unlikely to switch primary CAD tools any time soon. The challenge Autodesk is going to face is in getting Simulation DFM in front of those users (since PTC and SolidWorks sales reps and dealers are not likely to recommend it.) Maybe not so much of a challenge: Many of Autodesk’s existing Moldflow customers are Pro/E and SolidWorks users.

There’s a certain charm to software that does something of great value, but does not impose any extra demands on its users. Autodesk Simulation DFM looks like it may be that kind of product.

Autodesk, Inc. introduced its new 3D design and engineering software portfolio for manufacturers, including the new Autodesk Product Design Suite that makes design, visualization, and simulation software easier to adopt, use, and maintain. The complete Autodesk Digital Prototyping software portfolio helps manufacturers to design and build better, more sustainable products, reduce development costs and get to market faster.

Autodesk offers three editions of the Product Design Suite:

Product Design Suite Standard ¾ Foundational product design tools for conceptual design,  intuitive 3D surface and solid modeling, drafting and presentations, featuring AutoCAD Mechanical with Inventor Fusion, Autodesk Showcase, Autodesk SketchBook Designer, Autodesk Vault and Autodesk Mudbox software.

Product Design Suite Premium ¾ Optimized Digital Prototyping and visualization tools for maximum performance that features Standard edition tools along with Autodesk Inventor and Autodesk 3ds Max Designsoftware.

Product Design Suite Ultimate ¾ Advanced surfacing, simulation and tooling for unbeatable design quality, featuring the same tools as the Premium edition along with Autodesk Inventor Professional and Autodesk Alias Design software.

Launched in 2010 and updated this year, Autodesk Factory Design Suite 2012 is a factory layout and optimization solution that helps manufacturers make better layout decisions through the creation of a digital factory model, helping save time and money. It offers factory specific functionality in both AutoCAD Architecture and Autodesk Inventor, combined with Autodesk Navisworks’ visualization and analysis and Autodesk Vault to improve collaboration. New additions to the suite in 2012 include AutoCAD Mechanical for automating mechanical CAD tasks and 3ds Max Design and Showcase for enhancing communication and bids.

 

As a result of the strategic partnership announced in Oct. 2010, Autodesk and Granta Design Ltd. have built new design methods into Autodesk Inventor 2012 software that help designers estimate a product’s environmental impact and make more sustainable design decisions. The new Eco Materials Adviser in Inventor 2012 addresses sustainable design requirements early in the design process — when it matters most — enabling manufacturers to choose materials that minimize environmental impact without compromising on cost and performance. Powered by Granta’s expert materials database and proven sustainable design methodology, Eco Materials Adviser helps guide material selection and generates eco-impact reports so engineers can record and communicate the benefits of their sustainable design decisions.

Autodesk Inventor Fusion makes its commercial debut following its popular technology preview on Autodesk Labs. It is now included at no extra cost as a companion application to Autodesk Alias Design and Alias Automotive, Autodesk Inventor, Autodesk Moldflow, Autodesk Simulation and AutoCAD products. Inventor Fusion provide robust 3D modeling ease-of-use and direct modeling for rapid design changes. It also unites direct and parametric workflows within a single digital model created in Autodesk Inventor.

Along with the Autodesk Product Design Suite, each product in the Autodesk Manufacturing portfolio offers  new capabilities, spanning conceptual design, engineering, manufacturing, and technical documentation.

AutoCAD Electrical 2012 software expands its support for international standards and     now allows electrical controls designers to view, edit and share their DWG files on web browsers or mobile devices through AutoCAD WS .

AutoCAD Mechanical 2012 software now enables editing 3D models from any source with   Inventor Fusion and intelligent drawing view creation with a new model documentation feature. Also new is mobile and web viewing and editing through AutoCAD WS, so mechanical engineers can spend more time innovating.

 

Autodesk 3ds Max Design 2012 visualization software enables you to demonstrate the operation of designs in real-world settings, providing seamless aggregation of CAD data and transforming digital prototypes into high-quality visuals with “push-button” rendering, cinematic-quality animation and effects and an extensive material and texture library.

Autodesk Alias 2012 products ― Alias Design, Alias Surface and Alias Automotive software ― make it easier to create accurate 3D models with Class-A surfaces and feature improvements to the technical surfacing process with modeling tools that are dramatically easier to use.

Autodesk Inventor 2012 software provides easier ways to interact with 3D mechanical design data; new opportunities for sharing, accepting and updating CAD data regardless of source and complexity; and high-impact performance and productivity improvements for both users and IT departments.

Autodesk Inventor Publisher 2012 software makes it easy to create highly visual and interactive assembly instructions, operating procedures and technical documentation from 2D and 3D CAD data. Users can publish interactive, 3D instructions in multiple formats directly to iPhone, iPad, and iPod touch mobile devices.

Autodesk Moldflow 2012 software introduces new real-time injection-molding simulation functionality, enabling dynamic evaluation of a range of plastic part design alternatives in a fraction of the time it takes to perform a standard simulation, helping to pinpoint the best design more quickly.

 

Autodesk Showcase 2012 visualization software is a key element of the Product Design Suite, transforming CAD data into compelling imagery, movies, and interactive presentations to improve the design review process, secure internal buy-in and win competitive bids.
