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 half the cross-section of your object (like slicing a cup in half) and a center line. Fusion 360 sweeps that profile 360° to create the full shape. Best for: Creating the main body of round objects like chalices, bowls, or lamp bases.
2. Shell
Definition: Hollows out a solid body. How it works: You select a solid block (or revolved cylinder) and select the top face to "open." Fusion removes the inside material, leaving walls of a specific thickness. Best for: Turning a solid "Revolved" block into a hollow container that can actually hold liquid.
3. Pipe
Definition: A "shortcut" tool that creates a solid tube or rod along a sketch path. How it works: Instead of drawing a circle and sweeping it manually, you just draw a Line (the path). Select the Pipe tool, click the line, and choose the shape (Circle, Square, or Triangle). Best for: Creating handles quickly without needing complex profile sketches.
4. Mirror
Definition: Creates an exact copy of a feature, body, or face across a plane. How it works: Instead of modeling the left handle and then trying to model the right handle exactly the same way, you model one. Then, you select that "Pipe" feature and the center plane to generate the other side instantly. Best for: Ensuring perfect symmetry.
5. Extrude
Definition: The primary tool that gives depth to a 2D sketch. How it works: Pushes or pulls a profile to add or remove material. Best for: Adding distinct details that aren't round, like a square base or a plaque on the front of the object.
6. Fillet
Definition: Rounds off sharp edges. How it works: Applies a radius to smooth transitions. Best for: Blending the "Pipe" handles into the "Revolved" body so they look like they are welded or cast together, rather than just intersecting.
All dimensions are in mm/g/s/ISO
