Learn how Autodesk Assistant helps automate fillet selection in Autodesk Fusion by recognizing repetitive geometry patterns, reducing manual work, improving accuracy, and keeping design timelines clean.

Stop clicking every edge: Automate fillet selection with Autodesk Assistant
Whether you’re designing injection-molded parts, lattice structures, housings, or complex mechanical components, selecting dozens or hundreds of similar edges can quickly become one of the most tedious parts of the modeling process. The design work is already done. The challenge becomes manually finding and selecting every edge that needs the same treatment.
Autodesk Assistant helps eliminate that repetitive effort. By recognizing patterns in your selections, it can identify matching geometry and expand those selections automatically, allowing you to spend less time clicking and more time designing.
The problem with manual fillet selection
Fillets are essential in product design. They improve manufacturability, reduce stress concentrations, enhance durability, and create cleaner, more polished products. But when fillets must be applied across repetitive geometry, the process can become surprisingly time-consuming.
Consider a common example: an injection-molded component with a grid of reinforcing ribs. Every vertical edge requires a small radius. Applying the fillet itself takes seconds. Selecting every edge can take significantly longer.
This creates several challenges:
- Lost productivity: Repetitive edge selection adds time without adding design value.
- Missed geometry: Manually selecting dozens of edges increases the likelihood of overlooking one or two.
- Messy timelines: Designers often create multiple fillet features to manage selections, making models harder to maintain.
- Interrupted workflow: Repetitive tasks break design momentum and distract from higher-value engineering decisions.
These small inefficiencies add up over the course of a project.
Let Autodesk Assistant find the patterm
Instead of manually selecting every edge, the assistant can analyze a small sample of geometry and identify similar edges throughout the model.
The workflow remains simple and fully under your control.
Step 1: Select representative edges
Start by selecting several edges that represent the pattern you want to fillet.
In many situations, four similar edges provide enough information for Autodesk Assistant to understand your intent.
Step 2: Create or edit a fillet feature
Work within a single fillet feature whenever possible. Consolidating selections into one operation typically results in a cleaner, easier-to-manage timeline.
Step 3: Describe what you want
Ask Autodesk Assistant to identify and include matching edges while keeping the selection organized within a single feature.
Because the Assistant can interpret design context, it can expand your initial selection based on the pattern you’ve established.
Step 4: Review the results
The Assistant identifies similar geometry and completes the selection automatically, eliminating much of the repetitive clicking that would otherwise be required.
The result is a faster workflow, more complete coverage, and a cleaner design history.
More time for design, less time for selection
When repetitive selection tasks are automated, designers can spend more time focusing on:
- Product functionality
- Design for manufacturing (DFM)
- Cost optimization
- Material selection
- User experience
- Product innovation
Autodesk Assistant helps remove workflow friction so you can focus on solving engineering problems instead of managing repetitive geometry.
Keep your timeline clean
As models become more complex, timeline management becomes increasingly important.
Multiple fillet features created solely to simplify selection can clutter design history and make future edits more difficult.
By identifying and selecting repetitive geometry within a single operation, Autodesk Assistant helps maintain:
- Cleaner feature histories
- Easier model updates
- Improved design intent
- Better collaboration across teams
For large assemblies and long-lived projects, these benefits can significantly improve maintainability.
AI that works alongside designers
Autodesk Assistant isn’t making design decisions for you.
You still determine:
- Which edges should receive fillets
- Fillet dimensions
- Design intent
- Manufacturing requirements
- Final validation
The Assistant simply handles the repetitive selection work that consumes time without requiring engineering judgment.
Think of it less as automated design and more as automated busywork.
By recognizing patterns and expanding repetitive selections automatically, Autodesk Assistant can help reduce manual work, improve consistency, and keep your design history organized.
The next time you’re staring at a grid of identical edges, let Autodesk Assistant do the selecting while you focus on creating better products.
