The best I can find is here: https://help.autodesk.com/view/fusion360/ENU/?guid=ASM-TIMELINE
but there is no list of icons and definitions. Some icons give a description when you mouse over it but not all do or are clear.
Google search (Gemini) spit this out when I was looking for this answer, but again, not a nice little table with an icon on one side and a description on the other.
Yes, the timeline in Autodesk Fusion 360 has a reference guide for its symbols and functions. The timeline captures the history of your design, and the icons represent the different features and actions you have performed. [1, 2]
Common Fusion 360 timeline icons
Design features
- Sketch: An icon representing a pencil drawing a shape. Double-clicking this icon takes you into the sketch environment so you can edit it.
- Extrude: A square with a 3D extrusion arrow pointing out of it. This represents a body that has been extruded from a sketch.
- Revolve: An icon showing a half-circle revolving around a center axis. This represents a feature created by revolving a sketch profile.
- Sweep: An icon showing a shape being swept along a path.
- Loft: An icon representing a lofted feature, which transitions a shape between two or more sketch profiles.
- Fillet/Chamfer: A square with a rounded or chamfered corner. These icons represent modifications to edges on a 3D body.
- Hole: An icon that looks like a drill bit.
- Pattern (Circular/Rectangular): Icons showing a repeated pattern, created with either a circular or rectangular command. [3, 4, 5, 6, 7]
Assembly and components
- Component: Represented by a cube in the browser and sometimes color-coded in the timeline if the Component Color Swatch is enabled.
- Joint: An icon representing a joint used to define the motion between two components. [8, 9, 10, 11, 12]
Informational symbols
- Suppressed Feature: A feature icon that is dimmed or grayed out in the timeline. The feature is temporarily inactive and not displayed in the canvas.
- Errors/Warnings: A feature icon with a yellow or red background indicates that a feature has a problem and needs to be resolved.
- Dependent Feature: When you select a feature, small hash marks appear on other features in the timeline that depend on it.
- Renamed Feature: You can right-click any icon and rename it, which is helpful for keeping track of specific actions in a complex design. [13, 14, 15, 16, 17]
