Fusion 360 Leaps Into the Cloud with Extensions and Forge

At its Autodesk University 2021 conference, Autodesk announced upcoming features for Fusion 360 such as generative design updates and integration with the company’s cloud-based Forge platform.

1. Everything Will Get a Forge Update

Autodesk plans for Forge to underpin all its products, granting users the ability to share data across Autodesk and third-party applications without requiring data translation. Moreover, Autodesk president Andrew Anagnost says that the company hopes to “unlock the capabilities of our entire portfolio of products by collapsing them into common Forge components, making these capabilities available outside the confines of an individual product.”

What does this mean? Anagnost says individual products won’t be going away, but “the capabilities found in any one product today will be available in many different workflows tomorrow,” making collaboration simpler than ever before.

Users will also be able to share specific selections of data as needed. Examples include cost and supplier data (powered by Autodesk’s acquisition of the Upchain PLM system), as well as metadata extracted from models and even full visualizations of multiple file types. Autodesk says its Forge data services are compatible with audit trails, revision tracking, data event monitoring and the EU’s General Data Protection Regulation (often called GDPR).

Autodesk’s Product Design extension is planned to automate the creation of several difficult features, including lattices and other types of non-linear procedural patterning. This image is of a product in development, and may not represent the final product.

2. Manufacturers Get a First Look At Forge — In Fusion 360

Autodesk is beta-testing Forge integration in Fusion 360 through the “Manage” extension. The current version of this integration uses a “product information model” to store property data from 3D models created in Fusion 360 and mirror it to the cloud. Users can read files and track events through the extension, with writing capability planned in the near future.

End-user applications for this extension include assigning a unique ID to design iterations to enhance traceability throughout the product lifecycle, tracking full design change history to ensure compliance, and leveraging a pre-configured workflow to track electronic approvals and release approved data.

3. Extensions Expand Capabilities

As Autodesk’s goal for Fusion 360 is to provide an end-to-end design and manufacturing solution, extensions that add capabilities to the core CAD software have long been part of its business model. At the conference, the company showcased two new extensions that leverage the power of cloud computing: a simulation extension, and a product design extension.

The simulation extension moves existing cloud simulation capabilities from a pay-per-project model to a subscription model. This mirrors the business model the company launched for Fusion 360’s cloud-based generative design capabilities in June 2021. Autodesk recommends users who only sparingly make use of cloud simulation continue to use the pay-per-project model, while power users should switch to the extension.

The product design extension provides access to tools that automate the creation of traditionally difficult or impossible geometries. One example is the Volumetric Kernel, which can perform non-linear procedural patterning to automate the creation of complex internal structures like lattices. Stephen Hooper, vice president and general manager of Fusion 360, says this extension is primarily for consumer goods, but other markets can make use of these features as they see fit.

4. Core Features Mature

Rob Cohee, director of product management for Fusion 360, described three focus areas for feature development: design concurrency, depth and modeling capabilities, and documentation.

In the context of Fusion 360, design concurrency means using multiple smaller documents as individual parts, then placing these parts into larger assembly documents as references. This enables multiple users to work on a project at once without getting under one another’s feet. Edit-in-Place functionality enables revisions to referenced files within the assembly, and Assembly Context gives users working on the single-part documents the ability to reference geometry of the overall assembly.

Fusion 360’s modeling performance and stability also improved in 2020 and 2021. Several new features also provided groundwork for the product design extension. For example, Manufacturing Driven Design functionality for plastics repeats programming rules to speed up the addition of lattices and other common manufacturing features.

Documentation has steadily improved in the software as well, with Cohee drawing attention to the recent additions of user-requested features like broken views and weld symbols. Cohee and the rest of the Fusion 360 team plan to continue this momentum in the months to come with auxiliary views, hole tables and improved support for DIN/JIS standards.

Autodesk’s upcoming Simulation extension will provide users with a subscription option for the company’s existing simulation capabilities, which have long been offered on a credit basis. This image is of a product in development, and may not represent the final product.

Al Whatmough, Autodesk’s director of product management for manufacturing, further expanded this list of updates with discussion of how Fusion 360 has progressed its compatibility with common manufacturing processes.

Toolpath editing and additional automation strategies increase milling flexibility, and support for five-axis control will continue to develop in future updates. Turning support has manifested over the past year in the launch of a more robust method of calculating material removal, as well as profile and threading strategies with grooving tools. Part handling strategies for machines with multiple spindles will arrive in later updates. Autodesk has also continued to build out Fusion 360’s support for additive manufacturing on both desktop and industrial machines.

5. Generative Design Takes Large Steps in Fusion 360

Generative design within the Fusion 360 environment, according to Fusion 360 senior product manager Mike Smell, focused on awareness, accessibility and applicability in 2021. The Generative Design extension provides mechanical engineers with automated design tools that leverage user-defined parameters to produce forms optimized for geometric connections, performance objectives, manufacturing considerations or material selection.

For additive manufacturing, a December 2020 update to the extension improved its capability to meet overhang angle and minimum thickness definitions. This update focused on minimizing the support material required for a build, and the result eliminated the step pattern that had previously plagued the extension’s AM results. The May 2021 update expanded manufacturing constraint support in previews, with improved shape and solver strategies for creating outcomes with two-axis cutting, 2.5-axis milling and additive manufacturing. An update in July 2021 added further support for additive manufacturing constraints, including the ability to define symmetry all the way to the outcome.

Future plans for the extension focus on the improvement and expansion of manufacturing awareness during shape generation. Optimization of additive orientations should improve the software’s ability to work with shape and printability, while casting for die and mold will receive support as a manufacturing constraint — this support is planned to lead into a sand casting workflow. Generative design for thin structures is also planned, with potential downstream manufacturing processes like cutting out and welding a nest of plates or bending and forming sheet metal.

Autodesk is also planning to launch a new “Generative Design for Modeling” workflow that can rapidly explore design alternatives, with a focus on geometric connections. The company hopes this will create an on-ramp between shape creation and performance/objective-based workflows. A “Generative Design for Fluid Paths” workflow is also under development, with expected use cases in complex ducting, manifold distribution and flow control devices.
