In this CAD tutorial we'll use the features:
1. Extrude
Definition: The standard tool for creating 3D geometry from a 2D sketch. How it works: You select a closed profile and pull it in a straight line. Best for: Creating the rigid, blocky parts of your design, like a mounting base or a connector.
2. Sweep
Definition: Extrudes a profile along a specific path. How it works: You need two sketches:
The Profile: The shape you want (e.g., a circle or hexagon).
The Path: The line it follows (e.g., an S-curve). Fusion drags the profile along the path to create the shape. Best for: wiring, hoses, paperclips, or organic handles that curve in multiple directions.
3. Shell
Definition: Hollows out a solid body. How it works: You select a face to remove (like the end of a hose) and set a wall thickness. Best for: Turning your solid "Sweep" into a hollow pipe or tube.
All dimensions are in mm/g/s/ISO
