In this CAD tutorial we'll use the features:
1. Extrude
Definition: The primary tool for creating 3D geometry from a 2D sketch. How it works: You sketch a closed profile and pull it to create a solid block. Best for: Creating the rough main shape of your object.
2. Offset Plane (Construction)
Definition: Creates a new sketching canvas parallel to an existing face but at a specific distance away. How it works:
The Problem: You want to add a button or a screen above the main surface, but the surface is curved or you need it at a specific height.
The Solution: Create an Offset Plane 10mm above the top face. Draw your button sketch there and Extrude down to the body. Best for: Creating features at different "levels" or elevations.
3. Fillet
Definition: Rounds off sharp edges. How it works: Apply smooth radii to the outside corners of your extrusion to make it ergonomic (comfortable to hold). Best for: Smoothing the blocky "Extrude" shape into something that looks like a finished product.
4. Shell
Definition: Hollows out a solid body. How it works: You select the bottom face of your solid part and define a wall thickness (e.g., 2mm). Fusion removes the inside material, leaving a thin outer skin. Best for: Instantly turning a solid block into a plastic casing.
5. Mirror
Definition: Creates a symmetrical copy. How it works: You model only the left half of the mouse. You Extrude, Fillet, and Shell that half. Then, you use Mirror to generate the right half perfectly. Best for: Saving time. You never want to manually model the left and right sides of a symmetrical object separately.
