Can you create a ʼCircular Patternʼ to repeat a feature around an axis in Autodesk Fusion?

Short Answer

Yes — in Autodesk Fusion, you can use a circular pattern to repeat a feature around an axis by selecting the feature, defining a rotation axis, and setting the quantity and angle. The most common professional method is the Solid workspace pattern tool. A limitation is that unstable reference geometry can cause the pattern to fail after model edits.

What You Need to Know Before

Warning: Circular Pattern in Fusion depends heavily on a valid axis and a stable feature history. If you pattern features that rely on faces likely to change later, the patterned instances can fail or lose references during updates.

How to Create a Circular Pattern in Autodesk Fusion

• Command: Circular Pattern

• Shortcut: None by default

• Quick Steps:

  1. In the Solid tab, go to Create > Pattern > Circular Pattern.
  2. In the dialog, set Pattern Type to Features, then select the feature to repeat.
  3. Select an axis under Axis, enter the Quantity, set Angle to 360 deg if needed, and confirm with OK.

Variables & Settings

• Key Setting: Pattern Type

  Choose Features, Bodies, Faces, or Components depending on what you need to repeat. In professional workflows, Features is usually best because it keeps the design intent and timeline behavior cleaner than face-based patterning.

Why it Fails

• Cause 1 (Geometry): The selected feature references faces or edges that change after edits, so Fusion cannot rebuild the patterned instances correctly.

• Cause 2 (layers/Locks): If the axis comes from a hidden construction axis, suppressed component, or inactive component context, selection can fail or produce the wrong pattern result.

• Cause 3 (Command/Logic): The wrong Pattern Type is used, such as patterning faces instead of features, which often breaks more easily when the model changes.

Quick Fix & Best Practice

• Quick Fix: Create a dedicated Construction Axis first, then rerun Circular Pattern using Pattern Type = Features and enable the correct angle/quantity values.
• Manager’s Verdict: Use Circular Pattern for holes, cuts, ribs, and repeated mechanical features around shafts or hubs. Avoid it on fragile face selections when the model is still changing.

FAQ

Can you pattern a body instead of a feature in Fusion?
Yes, by changing Pattern Type to Bodies.

Can Circular Pattern use a custom angle instead of full 360 degrees?
Yes, you can enter any angle value in the pattern dialog.

Why does the pattern not update correctly after editing the model?
Usually because the original feature or axis reference is no longer stable.
