Usability

A Smoother, Faster Fusion

As part of our ongoing efforts to make Fusion faster and more responsive, this release includes significant foundational performance enhancements that elevate your experience. Here are some of the highlights:

·      Windows Selection: Up to 10% faster when performing on large designs.

·      Invert Selection: Up to 40x faster inverting selections on large designs. 

Note: These improvements are based on datasets provided by our customers, and performance gains may vary depending on the specific dataset. 

Data Management

BOM Auto Refresh (Fusion Manage)

The Bill of Materials now updates automatically in real time as events occur within Fusion Manage workflows. Changes from Assign Item Number, Quick Release, and Change Orders are reflected instantly, ensuring the BOM always displays the most current information.

No manual refresh required. Your data stays in sync across workflows, reducing the risk of working with outdated information, improving accuracy and minimizing errors.

Hide Children

You can now treat entire sub-assemblies as a single component in the BOM, making it easier to simplify ordering and procurement workflows. This behavior can be configured in Fusion Desktop, Fusion Manage, or the Fusion web client. While BOM subcomponents are hidden, Fusion continues to maintain accurate physical properties such as mass.

Design

New Isoparametric Curves

Sketch > Create > Project/Include > Isoparametric Curve

Take surface modeling precision further with isoparametric curves, now available directly in the Sketch environment. Designed to give you more control where it matters most, these curves help refine loft profiles and rails, support mid surface continuity, and enable more intentional surface connections.

You can now extract surface U or V curves in two flexible ways. Use Single to place a curve by selecting a direction and defining an offset. Or choose Distributed by choosing a direction and number of curves to be equally distributed over the surface. 

Because isoparametric curves are fully parametric, they respond intelligently to upstream changes. As the surface evolves, the curves update automatically to reflect changes in size and shape. For even more creative freedom, leverage blend curve connected to an isoparametric curve to sculpt smooth, continuous transitions with confidence.

Snap Points for Points at Vertex

Construction Geometry > Point at Vertex

Snap Points are now supported for Point at Vertex, making it easier to create construction points with greater precision across a wide range of geometry. Snap Points provide accurate placement directly on key geometric references, even when no explicit vertex exists.

You can snap to vertices, face centers, edge points, edge centers, sketch points, and tangential points on curved surfaces such as spheres, cylinders, and tori. A dynamic preview helps visualize placement before selection, while maintaining backward compatibility with existing models.

This enhancement removes guesswork and improves accuracy when working with complex or curved geometry. By enabling point placement in locations that were previously difficult or impossible to reference, designers can work more efficiently, reduce errors, and move through workflows with greater confidence.

To use Snap Points, activate Point at Vertex, hover over the desired geometry, and select from the available snap points. Tangential points are automatically computed for curved faces.

Auto Look at Sketch Improvements

Preferences > Design > Auto look at sketch

Auto look at Sketch now offers three flexible behaviors, giving you greater control over how the camera behaves when entering the Sketch workspace. With Off, the camera remains fixed and does not rotate as you enter the Sketch workspace. Always Orthographic, the default setting, automatically rotates the camera and switches to an orthographic view for a consistent, sketch focused orientation. User Camera Settings preserves the current ViewCube camera settings when entering the Sketch workplace.

These options only affect camera behavior when entering the Sketch workspace and do not override existing ViewCube camera settings.

Configure Constraints

In this release, we’re introducing initial Configuration support for the Constrain Components command, making it easier to control and reuse constraint settings without the need to recreate similar geometric relationships. You can now configure Suppression to determine whether a constraint participates in each configuration, adjust orientation by configuring the Flip aspect, and adjust position by configuring the Offset or Angle aspects. This update represents an important step toward more flexible configurable constraints.

Learn more about configuring parametric features.

Other Enhancements

Drawings

Consistent Unit Conversion for Dimension Tolerances 

Dimension tolerances in drawings now update automatically when document units are changed. When units are modified through Document Settings, both the nominal dimension values and their associated tolerance values are converted to the selected unit type.

This ensures all dimension annotations remain accurate and consistent throughout the drawing, eliminating the need to manually re-enter tolerances after a unit change and helping maintain precision with less effort.

Electronics

Enhanced Drill Assignment & Symbol Management

We’ve streamlined drill symbol management in Fusion Electronics with a more flexible system. Drill-symbol visibility and editing are now integrated into both global preferences and per-design settings, giving you the ability to set defaults for all designs, but then tailor the drill legend to each design and its drill data. 

All assignments are saved with the design file, ensuring portability and consistency across workflows. You now have access to 44 symbols—18 graphical and 26 letter-based—for clearer documentation of PCB hole specs. Symbols are auto-assigned to drill sizes lacking user-defined values, replacing the previous default Ø with the next available symbol.

Search for Component by Attribute Values

Electronics > Place > Place Components

You can now search by attribute values in the Place Panel to find the right components for your designs more quickly. The search box searches across all attributes by default. To narrow your results, use the search options dropdown to limit the search to specific attributes.

Attach Existing 3D Model to Footprint

Electronics > Library Editor

The “Attach Existing 3D Model” option now allows you to attach a STEP file or any design in your hub directly to a footprint. This automatically creates a single package for you, keeping your data panel clean and organized as you import STEP files.

Simulation

New Simulation Results Experience for LSS, Thermal and Thermal Stress

The post processing experience for Linear Static Stress, Thermal, and Thermal Stress studies has been modernized.

The updated interface delivers:

• Guided Safety Factor insights
• Consolidated result and legend controls
• A redesigned animation bar
• A unified cutting plane dialog

Note: The remaining structural simulation studies will continue to show the Classic Results experience. We plan to add this new experience to those studies in the future.

Results Guidance for Linear Static Stress study

A new guided visualization helps answer one of the most important questions in stress analysis: does the design meet the required minimum safety factor?

The Guided Results experience analyzes the result and provides information on what is happening, why it happened and gives recommendations on the possible next steps you can take to improve your results. Adjust safety factor values directly in the legend or results view and the guidance updates automatically, helping you iterate with confidence.

Result Settings and Legend Options

Result settings and legend controls are now consolidated and positioned directly next to the legend. Easily manipulate the legend as well as result settings to get a suitable visualization of your results.

New Animation Experience

Animation is now accessible through the animation bar at the bottom of the screen, replacing the previous command dialog workflow. There are also additional control options available now to improve the overall usability of animation for simulation results.

New Cutting Planes Experience

Additionally, there is now a new dialog for cutting planes, consistent with Injection Molding and Electronics Cooling simulation. You can now create and modify multiple cutting planes in the same dialog with additional controls available on styling and type of cutting planes.

Note: This new experience only allows you to use the central XY, YZ and ZX planes to create cutting planes. We will add the ability to create cutting planes using any point or surface on the model in the future.

Modernized Simulation Reports Format

We’ve heard your feedback on the updated report format introduced for Injection Molding, and we’re extending that experience to Linear Static Stress (LSS), Thermal, and Thermal Stress studies. The refreshed format offers a cleaner, more modern look along with additional customization options to help you better present and share your results.

Note: Reports in the new format are currently generated one study at a time. Support for creating a single report across multiple studies is coming in a future update.

New Compare Experience

Account > Preferences > Preview Features > Simulation

Welcome to a new experience in the Compare environment. This experience includes the existing capabilities of creating multiple views to compare multiple studies as well as syncing of cameras, result types and legend. But this is just the beginning, stay tuned as more capabilities will be made available for the Compare environment in the future.

Apart from the above-mentioned items, you will also notice improved experience in other areas of Simulation results as well for these 3 study types. 

Additional Details

If you run into any issues with the new Simulation results experience for the Linear Static, Thermal and Thermal Stress studies, don’t worry, you still have the option to switch back to the classic results experience for these studies through User Preferences.

Manufacturing

New Intermediate Curves for Blend

When Stepover Calculation is set to From Tip of Tool and drive curves are defined explicitly, you can now define additional drive curves between the start and end drive curves to control how the blend progresses. This allows complex regions to be machined in a single toolpath when the start and end drive curves differ significantly.

These intermediate drive curves must correspond to surface edges within the machined region and be positioned between the start and end drive curves in the list of selected curves.

Toolpath Modifications for Roughing Strategies (MFG Extension)

You can now optimize 3D Adaptive and 3D Pocket toolpaths by applying modifications such as Trim, Delete Passes, and Leads and Links. When Trim or Delete Passes modifications require new leads and links, safeguards are applied to avoid plunges into stock. However, the resulting leads and links may not be optimal, such as the use of helical leads or full retraction links.

These results can be further refined by applying a Leads and Links modification, though this refinement considers the model only and does not account for the stock.

Note: This feature requires enabling the corresponding Optional Feature in the Preferences dialog. Edits may result in unexpected tool movements through the stock. Simulation and careful review of the results are strongly recommended.

Faster IPS Calculations

General > Manufacture > IPS and Remaining Stock > Processing Mode

A new preference is available that allows IPS and remaining stock calculations to run on the graphics processor. When set to Faster (graphics processor), subsequent calculations are performed on the GPU and may complete more quickly than the Standard option, depending on the GPU.

Learn more about Faster IPS Calculations. 

Machine Auto-transparency

An Auto option has been added to the Transparent setting, available through the graphics toolbar under Machine Visibility and through the machine simulation dialog under Machine. When set to Auto, now the default, machine components that obscure the tool tip, or the center of the model when no tool is present, automatically become transparent when view rotation stops.

Learn more about Machine Auto-Transparency. 

Additive Manufacturing

Multi-axis Rotations Added for True Shape Additive Arrangements.

We are excited to introduce multi-axis rotations for the True Shape arrangement methods in Additive Arrange. This rotates components around multiple axes sequentially, helping to find more orientations and often resulting in a higher packing density.

New Move to Corner/Center Move Command Options

Based on your feedback, we’ve replaced Move to Origin in the Additive Move command with two new options, Move to Corner and Move to Center. These additions give you greater control over how parts are positioned within the build volume, making it easier to place components exactly where you need them.

Component Pre-Selection

You are now able to preselect your components when using the Move, Duplicate, Remove from Setup, and Minimize Build Height commands. Using preselect you can select multiple components much easier with common selection tools such as rectangle select which is not available when Move, Duplicate, Remove from Setup, and Minimize Build Height commands are active.

Additional Enhancements
