In this CAD tutorial we'll use the features:

1. Revolve

Definition: Creates a cylinder or ring by spinning a profile. How it works: You sketch a cross-section (like a rectangle or a notched shape) and a center line. Fusion spins it 360°. Best for: Creating the "Big End" of a connecting rod (the bearing housing) or bushings.

2. Extrude

Definition: Pulls a sketch into a solid block. How it works: Creates the main arm or shaft connecting two points. Best for: The structural beam that connects the Revolved hub to the other end.

3. Full Round Fillet

Definition: A special setting that completely rounds off a face using three selections (Side A, Center, Side B). How it works:

The Magic: You don't need to know the radius. You just select the two sides of a rectangular tab, and Fusion calculates the perfect semi-circle to cap it off. Best for: The "Small End" of a linkage. Instead of drawing a circle and trimming it, you just Extrude a rectangle and Full Round Fillet the end.

4. Combine

Definition: Merges separate solid bodies into one. How it works:

The Scenario: You often model the "Revolved Hub" as Body 1 and the "Extruded Arm" as Body 2 to keep your sketches simple.
The Fix: Use Combine (Join) to weld them together into a single manufacturable part. Best for: Cleaning up multi-body modeling.

5. Hole

Definition: Drills a precise hole. How it works: Select the center point of your new Full Round Fillet. Best for: Creating the pin hole in the linkage arm.

6. Fillet (Standard)

Definition: Rounds off internal edges. How it works: Adds a smooth radius where the Arm meets the Hub. Best for: Reducing stress concentrations. If you don't fillet the connection between the arm and the hub, the part will snap under load.

All dimensions are in mm/g/s/ISO
