3D Exercise 72

Exercise 72

In this CAD tutorial we'll use the features: 

1. Revolve

Definition: Creates a 3D solid by rotating a sketch profile around a center axis. How it works: You draw the cross-section of your object (like slicing a wheel in half) and a center line. Fusion 360 sweeps that profile 360° to create the full shape. Best for: Cylindrical or spherical objects like hubs, rims, bottles, or shafts.

2. Extrude

Definition: The primary tool that gives depth to a 2D sketch. How it works: You select a closed shape (profile) and pull it to add volume (Join), cut a hole (Cut), or make a new object (New Body). Best for: Creating connecting spokes, mounting tabs, or flat features that attach to your round "Revolved" parts.

3. Mirror

Definition: Creates an exact copy of a feature, body, or face across a plane. How it works: Instead of modeling the same arm or spoke on both sides, you model it once on the left. Then, you select the feature and the Center Plane (Mirror Plane) to instantly generate the right side. Best for: Drastically reducing work on symmetrical parts. "Model half, Mirror the rest."

4. Fillet

Definition: Rounds off sharp edges to create smooth transitions. How it works: You select the edges where your Extruded parts meet your Revolved parts. Best for:

• Stress Relief: Making the connection between a spoke and a hub stronger.

• Aesthetics: Making the part look like a single cast piece rather than separate blocks glued together.

•
