Fusion 360 Parametric Design and History 3

Question 1

What is the function of the 'Change Parameters' dialog in Fusion 360?

Accepted Answer

To view, create, and edit all model parameters including user-defined and driven dimensions

Answer

The Change Parameters dialog (Modify > Change Parameters) lists all sketch dimensions and user parameters, where you can edit values or add formulas.

Question 2

In Fusion 360, what does a yellow warning icon on a timeline feature indicate?

Accepted Answer

The feature has a warning — it succeeded but may have produced unexpected or suboptimal results

Answer

A yellow triangle icon indicates a warning — the feature was computed successfully but there may be a potential issue, such as a fillet radius exceeding face dimensions.

Question 3

What is the purpose of 'Capture Design History' in Fusion 360?

Accepted Answer

To switch the model from Direct modeling (no history) back to Parametric mode, starting to record timeline features

Answer

When history is turned off (Direct mode), Capture Design History re-enables parametric recording so subsequent operations are logged in the timeline.

Question 4

In Fusion 360 parametric design, what is a 'driven dimension' (also called a reference dimension)?

Accepted Answer

A dimension that is computed from existing constraints but cannot directly control the geometry

Answer

A driven (reference) dimension displays a size for information but is controlled by other constraints, so you cannot type a new value directly into it.

Question 5

What does it mean when Fusion 360 shows a feature in the timeline with a red 'X' icon?

Accepted Answer

The feature has an error and failed to regenerate — downstream features may also be affected

Answer

A red error icon means the feature could not be regenerated, often due to a deleted reference, invalid geometry, or a parameter value that produces an impossible result.
