What is the ʼCompute Allʼ command in Autodesk Fusion?
Short Answer
In Autodesk Fusion, Compute All forces the design to recalculate all features, sketches, and dependencies in the timeline so the model updates correctly after edits or errors. It is the most common professional way to refresh a parametric model when geometry looks out of date. It can be slow on large assemblies.
What You Need to Know Before
Warning: Compute All can expose failed features that were previously suppressed by partial updates, especially in complex parametric timelines. In large designs or linked components, a full recompute may also take significant time and reveal broken references that must be repaired manually.
How to Use Compute All in Autodesk Fusion
Command: Compute All
Shortcut: Ctrl+B
Quick Steps:
- In the Fusion workspace, go to the top menu bar and click Modify > Compute All.
- Or use the faster professional method: press Ctrl+B to force a full model recompute.
- Watch the timeline for any warning or error markers, then repair failed features if needed.
Use this when edits to parameters, sketches, or upstream features do not visibly update the full model.
Variables & Settings
Key Setting: Capture Design History
Expert Setting: Compute All is most relevant in parametric workflows when Capture Design History is enabled. If Design History is turned off, Fusion behaves more like direct modeling, and full recompute behavior is limited because there is no feature timeline to rebuild.
Why it Fails
Cause 1 (Geometry): A recompute can fail if an upstream sketch, face, or edge reference has changed, causing dependent features like extrudes, fillets, or patterns to lose their references.
Cause 2 (layers/Locks): In Fusion, the more realistic environment issue is a linked or read-only external reference, inserted component, or constrained context that cannot update as expected during recompute.
Cause 3 (Command/Logic): Compute All does not repair broken feature logic by itself; it only forces evaluation, so timeline errors remain if model dependencies are invalid.
Quick Fix & Best Practice
- Quick Fix: Run Compute All with Ctrl+B, then right-click the first failed timeline feature and choose Edit Feature or Redefine to repair the broken reference.
- Manager’s Verdict: Use Compute All after parameter changes, imported edits, or timeline reordering in parametric models. Avoid using it repeatedly as a substitute for fixing unstable feature references in poorly structured designs.
FAQ
What does Compute All do in Autodesk Fusion?
It forces Fusion to recalculate the full parametric design timeline.
What is the shortcut for Compute All in Fusion?
The standard shortcut is Ctrl+B.
Why does Compute All show new errors?
Because a full recompute reveals broken references or failed dependent features that were not fully updated before.
