Autodesk Fortifies Digital Prototyping with Ground-Breaking Inventor Features and New Products for 201113 May, 2010 By: Nancy Spurling Johnson
Direct manipulation, as-you-go visualization, and design automation are new for Inventor, and Inventor Publisher and Alias Design for Inventor join the product line.
For years Autodesk focused on transitioning its AutoCAD user base to 3D modeling. Today, the company reports, 3D is but a stepping-stone to broader design pursuits. At the Manufacturing Tech Day media event last month, Robert "Buzz" Kross, senior vice-president of the Manufacturing Industry Group, put it bluntly: "3D is not spectacular," he said, explaining that 3D CAD today is "just what you do — it's just a technique."
What Autodesk really wants you to embrace these days is digital prototyping — that is, using 3D design, visualization, and simulation tools to "experience products before they are built." Kross said Autodesk delivers digital prototyping as a complete package for manufacturing environments. "[That] is what it takes to compete today."
Autodesk's 2011 digital prototyping lineup includes some groundbreaking upgrades for Autodesk Inventor, a few new products, and enhancements across the board for product development professionals focused on conceptual design, visualization, engineering, and manufacturing. Software products are increasingly multidisciplinary, often supporting varied functions throughout the product-development process. Indeed, Kross stated at the event, many users today have a blend of previously distinct responsibilities, including creative design, engineering, and analysis.
What's New in Inventor 2011
Inventor 2011 is full of new features that support all facets of 3D modeling.
Direct model manipulation. New direct manipulation capabilities in Inventor 2011 are said to accelerate design times on common tasks such as assembly modeling by approximately 40%, compared with Inventor 2010. With direct manipulation, all the input needed for a command can be controlled right at the point where users are directly changing geometry. Dynamic input in the sketch environment helps engineers to sketch more freely and directly.
In-the-window visualization. An eye-catching new development, literally, is Inventor 2011's new in-the-window design visualization — it's "not a rendering," Kross emphasized. New shading, lighting, and material properties offer a more sophisticated, photorealistic representation of designs, updating as you go. An expensive modeling solution should offer graphics that are better than "those in a $50 game," Kross said.
Visual display in Autodesk Inventor 2011 features significantly improved shading, lighting, and material properties in the default work environment, giving a more realistic representation of the design at all times.
Simulation. Tools in Inventor Professional 2011 simplify creating and validating multiple design iterations. The new Simulation Guide walks users through the steps required to define the best scenario to represent the particular loads or interactions, making simulation accessible to new and occasional users by helping them to set up loads, constraints, and contacts as well as generate and interpret the results. Tools also enable engineers to simulate the performance of load-bearing frame models quickly. Referring to the advanced features now found in Inventor Professional 2011 and Algor Simulation 2011, Kross said, "We are ahead of what our customers need [for design analysis], which is unusual, but I think they'll be there soon."
Tooling. Inventor Tooling 2011 improves performance for a number of key operations by more than 50%, supports dynamic simulation of mold assemblies, and helps users automatically generate the mold core and cavity for a broader range of plastic parts, whether using native Inventor or imported files.
Design automation. ILogic technology, acquired by Autodesk last year, is now fully integrated in Inventor 2011 to offer rules-based design and design-automation tools that allow users to easily capture and embed engineering and product knowledge directly into virtual models. Autodesk compares this functionality with AutoLISP automation for AutoCAD, but is quick to point out that iLogic is accessible even to the non-programmer. The new iCopy feature lets users customize commonly used assemblies by automating the process of copying and positioning similar components. ILogic also can be used to build an automated configuration-to-order process.
3D print previews. Use the 3D Print Preview tool for a sneak peek at how a 3D printed prototype will look.
The 3D Print Preview in Inventor 2011 displays an accurate representation of the printed model.
BIM exchange. Enhancements to the AEC Exchange functionality in Inventor 2011 have improved data sharing between Inventor and Autodesk Revit or AutoCAD Architecture. To maintain consistency between Autodesk products, models published from Inventor now maintain the same visual fidelity of materials when imported into Revit and AutoCAD Architecture.
New: Alias Design for Inventor
Autodesk has introduced a version of Alias Design created specifically for Inventor users. Alias Design for Inventor 2011 ($3,995+) installs directly into Inventor and is fully integrated, offering freeform shape-modeling capabilities within Inventor's parametric modeling environment. A free trial is available for download.
Integrated freeform shape modeling capabilities are now available directly within the Inventor environment with the addition of Alias Design for Inventor 2011.
New: Inventor Publisher
Following its run as a technology preview on Autodesk Labs, Inventor Publisher ($2,500) debuts for creating clearer, more comprehensive technical instructions based on 3D CAD data. The software operates on a simple import-author-publish workflow.
- Import. Inventor Publisher imports product data from Inventor or any number of other 3D CAD solutions. Data imported from Inventor links back to the original model, so when that model is updated, the changes automatically reflect in Inventor Publisher. "Downstream documentation" becomes a term of the past because the documentation process can begin before product designs are final.
- Author. Users create exactly the materials they need for print or digital publication. Inventor Publisher was designed for use by non-CAD users.
- Publish. Completed projects can be published to a variety of file formats, including DWF, PDF, Flash, Microsoft Word and PowerPoint, and a variety of image formats, including high-resolution images for print publication.
The Flash format lets users create animations to convey design ideas, communicate assembly instructions, and more. Autodesk's patent-pending algorithm is behind a feature that can automatically "explode" a design to show disassembly.
The Inventor Publisher 2011 interface is designed to be simple enough that even non-CAD users can work with CAD-based data to create exactly the product documentation they need.
Other Digital Prototyping Updates
Other developments in the line of Autodesk products for digital prototyping include the following:
- AutoCAD Electrical 2011 software helps electrical controls designers to quickly create control system designs and more easily access extensive catalog information for large electrical controls projects.
- AutoCAD Mechanical 2011 software's streamlined design environment improves user access to power dimensioning functionality, which automatically aligns part dimensions with the rest of the drawing properties without ever opening a dialog box.
- Algor Simulation 2011 mechanical simulation tools now integrate with Autodesk Moldflow 2011 software, allowing engineers to utilize Moldflow simulation results and the Moldflow material database when performing structural simulations on plastic parts.
- Alias 2011 family — including Alias Sketch, Alias Design, Alias Surface, and Alias Automotive — delivers surfacing capabilities supported by industry-leading sketching, modeling, and visualization tools, according to Autodesk. In the new Alias Sketch, a hybrid paint and vector workflow helps creative professionals more quickly transform ideas into design iterations.
- Moldflow 2011 software helps users validate and optimize plastic part and injection mold designs before manufacturing begins. Users can now easily export Moldflow simulation results to Showcase 2011 visualization software to expose defects and see how the part will look in real life.
- Vault 2011 family, a workgroup solution for managing the complete digital prototype, even for globally dispersed workgroups, features a new visual experience for graphically mapping Vault information directly to Inventor models to streamline workflows, improve reporting and decision-making processes, and accelerate model selection and interaction. For example, a color-coded product can indicate which files are checked out or which office is working on those parts.
Time for a Hardware Upgrade?
With all the advances to design visualization and simulation functionality in the 2011 product line, will users need better hardware to support a software upgrade? Not necessarily, according to Kross. He said that new versions of Inventor, Algor, and Moldflow will leverage GPU power for those users who have it, and added that improvements throughout the 2011 line will be apparent without extra hardware investment.
A requirement for new product visualization in AutoCAD and Inventor was that it function efficiently without special hardware, said Amy Bunszel, director of mechanical products. But if you do upgrade to current processing technology, she added, "you will see some very noticeable gains" in 2011 product performance.
Sketchbook Pro for iPad
Kross also touted the relatively new Sketchbook Pro, a $7.99 drawing and painting application for the Apple iPad. "Most competitors don't have a product like this," he stated. The mobile app joins Sketchbook Mobile for the iPhone, released last year.
Product availability may vary by country, so consult the purchasing options listed on the Autodesk web site.
