In this CAD tutorial we'll use the features:
1. Hole
Definition: A specialized tool for creating standard drill holes, counterbores, and countersinks. How it works: While you could just Extrude a circle to make a hole, the Hole tool is smarter. You select a face or points, and then choose from a library of standard hardware sizes (e.g., "ISO M6 Screw"). It automatically cuts the correct diameter and creates the head clearance (counterbore) for you. Best for: Creating mounting points for screws, bolts, and fasteners without needing to look up drill charts.
2. Revolve
Definition: Creates a 3D solid by rotating a sketch profile around a center axis. How it works: Think of a pottery wheel or a lathe. You draw half of the object (the profile) and a center line (the axis). Fusion 360 sweeps that profile around to create a cylindrical or spherical shape. Best for: Round objects like wheels, pulleys, bottles, and chess pieces.
3. Extrude
Definition: The primary tool for turning 2D sketches into 3D forms by giving them depth. How it works: You select a closed sketch region and push or pull it.
Join: Adds material to an existing body.
Cut: Removes material (like a punch).
New Body: Creates a separate object. Best for: Creating the main geometric volume of almost any mechanical part (brackets, blocks, plates).
4. Fillet
Definition: Rounds the sharp edges of a solid body. How it works: You select an edge, and the tool creates a smooth radius. This creates a tangent transition between two faces. Best for:
Ergonomics: Making a handle comfortable to hold.
Strength: Reducing stress concentrations where parts often crack.
Manufacturing: Machining tools (end mills) are round, so they cannot cut perfect sharp inside corners; fillets mimic the tool shape.
All dimensions are in mm/g/s/ISO
