In this CAD tutorial we'll use the features:
1. Extrude
Definition: Creates the rough solid block or "clay" of your object. How it works: You sketch the outline (profile) and pull it into 3D. Best for: Establishing the overall size and shape of the part.
2. Fillet
Definition: Rounds off sharp corners. The Golden Rule: You must apply your major fillets to the outside of the solid block before you use the Shell tool. Why?
Uniform Walls: If you round the outside corners first, the "Shell" tool will automatically create perfectly rounded inside corners for you. This creates a constant wall thickness, which is critical for plastic molding (to prevent warping).
Stress: Sharp inside corners are weak points where plastic cracks. Filleting avoids this.
3. Shell
Definition: Hollows out a solid body. How it works:
The Magic: You don't need to draw the inside walls. You just select the Top Face (the opening) of your solid, filleted block.
The Action: You type a thickness (e.g., 2mm). Fusion removes all the interior material, leaving a thin skin that perfectly follows your exterior shape. Best for: Instantly turning a solid block into a functional cup, box, or housing.
All dimensions are in mm/g/s/ISO
