Alibre, Inc. announced the latest version of its flagship 3D CAD application, Alibre Design 10.0 ("V10"). Primarily driven by customer feedback, the new release includes improvements which further differentiate Alibre Design as the most accessible and easiest to use 3D mechanical CAD product on the market. In addition to improving key feature performance ten-fold and decreasing memory consumption by 35%, the application includes productivity improvements in 3D modeling, parametric sketching, and 2D detailing. A new fully integrated CAM add-on, Alibre CAM, supporting 2.5 and 3-axis NC machining, is also available as a component in Alibre Design Expert.
"We've gotten great feedback from our customers and partners who have had early access to V10, so we're excited about the release," comments CEO Greg Milliken. "Alibre has built a unique position in the market by listening to our customers, and V10 is a direct response to their feedback. They are telling us the product is working well. They want us to stay focused on the core functionality everyone needs and not to chase the bells and whistles of the competition -- just make the core faster, easier and more efficient. So that's what we did."
Alibre Design 10.0 delivers significant performance gains while more efficiently utilizing memory. Versus Alibre Design 9.2, equivalent operations are completed in half the time with 35% less memory consumption. The new "Fast Views" feature projects 2D views of large or complex models 4 to 10 times faster. In addition, a variety of detailing features are more responsive including inserting dimensions and annotations such as BOM callouts, creating and editing Views, and generating hidden lines and centerlines. Associative updates of drawing views after a corresponding change to the 3D model have also been improved.
Alibre Design 10.0 includes the new Direct Editing toolset, which is ideal for early-stage conceptual design and working with models imported from other CAD systems. This toolset provides intuitive push-pull modeling as well as the ability to quickly move, add and remove design elements. A new inferencing engine automates many functions within these new tools, further reducing the time it takes to make complex changes. It easily identifies a pocket made up of multiple faces by simply clicking on a single face or allows quick edits to imported geometry without having to go back to the originating CAD system.
Because the tools are so easy to use, at times completely replacing sketch and feature editing, people who are not CAD experts can easily complete previously complex tasks. Direct Editing opens up many new uses like a machine shop needing to make a quick change before manufacturing or a structural analyst removing small details like fillets that unnecessarily complicate FEA.
"CAD vendors seem to be breaking into two camps regarding the approach to 3D modeling," said Milliken. "One camp is completely invested in direct geometry editing claiming that is the only way to go, while the other is committed to parametric, feature-based modeling. For some, it's become a religious battle, which we find a little amusing. We see value in both approaches so we support them both, and we do it at a fraction of the cost of anyone else, even less than the maintenance cost of a product like SolidWorks."
A key addition with Alibre Design 10.0 is the new manufacturing add-on Alibre CAM, a fully integrated NC machining solution supporting 2.5 and 3-axis milling based on proven technology from MecSoft Corporation. Alibre CAM was developed using Alibre Design's API and runs entirely within the Alibre Design user interface. Like all other elements of Alibre Design, Alibre CAM is fully associative, so when a part is edited a previously defined tool path will update automatically. In addition, Alibre CAM supports a large selection of post-processors for popular machine tools as well as the ability to write custom post-processors for any machine.
Commentary By Jeffrey Rowe, Editor
In early 2000 (what seems like an eternity in the MCAD business), Alibre launched the first version of Alibre Design that emphasized a then-new peer-to-peer architecture for collaboration in addition to parametric, feature-based solid modeling. At about this same time, Alibre had a lot of competition from other companies who bet that the mechanical design world would be moving en masse to collaboration within weeks or months. Many of these companies are now defunct because they concentrated on the collaboration aspect of their applications at the expense of modeling features and capabilities. These companies unfortunately realized too late that users for the most part wanted to first
model, as well as collaborate.
This is a lesson that Alibre learned early on as it put forth greater effort in developing more robust modeling functionality in parallel with collaboration functionality. Today, with v10, the Alibre Design application family continues to mature into a well balanced combination of the two functionalities.
For mechanical designers, Alibre Design is available in the following four flavors:
Alibre DesignXpress (free and formerly known as X-CAD) - Basic 3D design capabilities.
Alibre Design Standard ($995) – Parametric solid modeling and associative 2D drafting and detailing plus built-in real-time collaboration tools.
Alibre Design Professional ($1,495) – Includes Alibre Design with integrated sheet metal design and data management tools, plus add-ons.
Alibre Design Expert ($1,995) – Includes Alibre Design Professional and even more add-ons for more comprehensive design work.
For those of you that care, the underlying modeling kernel and geometry engine is based on Spatial's ACIS R16 and the constraint management technology, for both 2D sketching and 3D assembly constraints, is based on DCM (Dimensional Constraint Manager) from D-Cubed.
In Alibre Design, all work takes place in windows called workspaces. There are five types of workspaces - part, assembly, sheet metal, drawing, and bill of material (BOM). Each workspace is displayed in a separate window; however, a drawing workspace can contain multiple drawing sheets. Also, you can have as many workspaces open as you need at any time.
The main part of a workspace is the graphical work area where you create parts, assemblies, and drawings. You can split the work area into as many as four views. You can zoom, rotate, pan and set various viewing modes (i.e., orthographic versus perspective, shaded versus wireframe, etc.) in each view independently. To activate a particular view, you click anywhere in the view border, and a red arrow is displayed that indicates the active view.
Like just about every parametric modeler, you create new parts in the part workspace by starting with a sketch, adding dimensions, applying constraints, and adding features. You then extrude, revolve, sweep, loft, etc. the 2D sketch into a 3D form, much like you do in most other contemporary modeling packages. In 3D there is a full complement of additional features, such as bosses, fillets, holes, chamfers, cuts, draft, patterns and shells, along with capabilities such as mirroring and scaling.
Sheet metal parts are designed by creating a new sheet metal workspace. Before starting to design a new sheet metal part, you can set important design properties, such as material thickness, minimum bend radius, k-factor, etc. You then create a base sketch of the sheet metal part, and then add features like flanges, tabs, closed corners, dimples and so on. You can also create punches across bend lines, cut features, and refold bends, and work in either the folded or unfolded state, switching freely between the two. Finally, you can flatten the entire sheet metal part in a single operation, although relief features, such as dimples, are not flattened so they can be dimensioned in a
Once you've modeled some parts, you're ready to assemble them. Like all other modeling tasks in Alibre Design, you first create a workspace for your assembly. You then identify parts and subassemblies that will comprise the assembly, and move them into position. You anchor (or lock) some parts in position and define relationships between other parts. You then apply constraints to create permanent relationships and dimensions between parts, mate and align faces, and so on. You continue this process by inserting more parts and adding more constraints until the assembly is complete.
In Alibre Design, a drawing can contain multiple drawing sheets, each created with user-defined or standard templates and drawing borders. 3D parts and assemblies are used to create standard orthographic views, as well as a full complement of other key view types including sections, details, and broken and auxiliary views. Dimensions can be placed as either driving design dimensions or reference dimensions that are driven by changes to the primary driving dimensions.
Hidden lines are automatically generated, along with support for centerlines and various other key annotations and symbols like GD&T, weld symbols, threads, and so on. The system also allows flexible control of dimension and annotation properties providing support for national and international standards, as well as custom corporate standards.
Exploded views of assemblies with support for BOMs and balloon callouts are also provided, along with a BOM editor that lets you customize the BOM. Finally, 2D drawings are bi-directionally associative with the model.
For v10, it sounds like there are a number of new and enhanced features that will benefit most users of Alibre Design Professional and/or Expert, primarily in the areas of performance and productivity.
A good example are the direct editing push/pull tools that let you edit or delete model features with a push or pull of the mouse, without having to be concerned with design history or editing features or sketches. Just grab a face and pull it up to increase its height, or click and remove fillets or nearly any model element for making rapid alterations without a design history. While Alibre is hardly the first to implement push/pull tools, they make a nice addition to the package.
This time around in v10, Alibre CAM is built into Alibre Design Expert. You can set machining commands for commonly used manufacturing processes and better ensure the model is built as specified. Alibre CAM’s biggest advantage is looks, feels, and behaves a lot like Alibre Design.
Alibre CAM is actually a 3D milling package built with CAM technology provided by MecSoft, developers of VisualMill, that includes 2.5- and 3-axis milling, as well as approximately 50 pre-built post-processors.
With Alibre CAM you can define tool paths and run machining simulations on part models from directly within Alibre Design Expert. Once the simulations are complete and tool paths defined, you can output G code to a machine tool and start cutting parts. The level of integration really comes into play when you have a design change to make. Since the tool paths are parametrically associated to the part, when a change is made to a part, the tool path updates automatically.
If you are in the market for a good mainstream modeler - and you have some flexibility on your demands for free-form surfacing and large assemblies, Alibre Design may be a good choice. Alibre Design does not have all the bells and whistles that some of the competition does, but that offers the benefit of making it relatively easy to learn and use. Alibre Design's collaboration capabilities are powerful and unique. The product has appeal for a wide spectrum of potential users, and users new to CAD (2D or 3D) should have a positive experience with Alibre Design as theyenter the world of 3D digital design. It’s also a good value for the money and the capabilities it offers. I’m
anxious to try v10 out for myself.
The Week’s Top 5
At MCADCafé we track many things, including the stories that have attracted the most interest from our subscribers. Below are the five news items that were the most viewed during last week.
Robert McNeel & Associates and SpaceClaim Corp. announced interoperability between Rhinoceros and SpaceClaim, enabling product stylists to include 3D mechanical design elements in their designs. The interoperability solution allows Rhino files to be opened directly in SpaceClaim for creating and modifying solid geometry. The 3D model can then be sent back in the Rhino file format for precise surface modifications by the industrial designer. SpaceClaim Professional 2007's intuitive 3D and Rhino's free form modeling are compatible. Industrial designers must work closely with product engineering to develop stylized
surfaces that also meet mechanical design requirements. This requires data exchange between surfacing and design applications. Rhino and SpaceClaim integration meets that need by enabling product stylists to create free-form surfaces in context of the product design. For instance, from within SpaceClaim industrial designers can directly modify 3D geometry, such as support ribs or bosses, which conform to the stylized surfaces. Precise surface modifications can be made within Rhino and accurately transferred to the SpaceClaim model. Product engineering benefits from receiving more complete designs that require minimal modification.
Noran Engineering, Inc. (NEi) announced that the U.S. Naval Academy has selected its NEi Nastran Finite Element Analysis (FEA) software for use in its accredited degree program in Naval Architecture. The Academy’s curriculum covers many different types of ships, boats, and vehicles that operate on, above, or under water and involves the analysis and simulation of hull shapes, stability, structure, arrangement, survivability, maneuverability, and seaworthiness. The objective is to have students learn modern techniques of marine vehicle design and analysis. Noran Engineering's NEi Nastran has a solid presence in the U.S. Naval community offering
highly specialized capabilities to Navy contractors such as the ability to simulate the response of ship components to shock loads like mine, torpedo, depth charge or missile detonation. Beyond the U.S. Navy, Noran Engineering's software extends to the global marine engineering community covering the industry from defense projects and commercial vessels to luxury pleasure crafts and high profile racing like the America's Cup and Volvo Ocean Race.
SAMTECH announced that it has been appointed by AIRBUS as “Referenced Supplier” for CAE and development services in structural analysis. Under this agreement, the Master Agreement Contract (MAC), signed between Airbus and SAMTECH, SAMTECH will provide CAE software and services to several AIRBUS sites and to all the AIRBUS partners worldwide registered under the “AIRBUS Extended Enterprise.” This AIRBUS decision is the result of the reliability of SAMTECH during a partnership between the two companies that started 20 years ago. SAMTECH also provides development and support services for Airbus parametric structure optimization
applications based on the SAMTECH BOSS Quattro platform and embedding Airbus proprietary knowledge and processes.
UGS PLM Software, a division of Siemens Automation and Drives (A&D) announced UGS PLM Software-sponsored racing team Andretti Green Racing (AGR) -- whose cars are developed with the help of UGS PLM Software technology -- won the 2007 Indy Racing League (IRL) IndyCar Series Championship. Andretti Green Racing uses UGS NX digital product development software for all of the design and development work the company performs on its fleet of eight race cars. Although IRL rules limit the modifications a team can make to the car body and engine, engineers still have quite a bit of leeway in other areas such as the suspension. Fine-tuning
these areas often means designing and fabricating new parts in the brief interval between races.
PTC announced the availability of the industry's first comprehensive out-of-the-box solution for creating, publishing and delivering technical service manuals. Built on Arbortext dynamic publishing software, this solution enables customers to publish high-quality service manuals with embedded interactive illustrations quickly with minimal configuration. The PTC service manual application is a solution that has the power to transform the process of publishing service documentation to significantly improve the quality and efficiency of service organizations. The service manual application includes capabilities to create text and interactive graphics,
collaboration, content management and configuration, and dynamic publishing. It is enabled by the latest release of the following Arbortext dynamic publishing software:
