In this CAD tutorial we'll use the features:
1. Revolve
Definition: Creates a 3D solid by rotating a sketch profile around a central axis. How it works:
Profile: You sketch the cross-section of the part (e.g., the "V" shape of a pulley groove).
Axis: You select the center line.
Action: Fusion spins the profile 360° to create a solid cylinder with that complex profile. Best for: Parts with radial symmetry like wheels, shafts, and flanges.
2. Extrude
Definition: Creates linear geometry (adds or removes material in a straight line). How it works:
Join: You can use it to add a keyway slot or a mounting boss to the center of your revolved part.
Cut: You can use it to cut a shape out of your revolved wheel (like cutting the space between spokes). Best for: Adding non-cylindrical features to a cylindrical part (e.g., keyways, bolt heads, lightening holes).
3. Circular Pattern
Definition: Duplicates features around a center axis. How it works:
Efficiency: Instead of drawing 5 separate spokes or 8 separate bolt holes, you draw one.
Pattern: You select that one Extrude feature and the center axis. Fusion calculates the math to space them perfectly evenly (e.g., 360° / 5 = 72° each). Best for: Creating spokes, bolt circles, or gear teeth.
4. Fillet
Definition: Rounds off sharp edges. How it works: Adds a radius to corners. Best for:
Castings: If your part is meant to be cast metal (like a heavy pulley), you need fillets on all internal corners to prevent cracking during cooling.
Aerodynamics: Smoothing the edges of spokes.
All dimensions are in mm/g/s/ISO
