In this CAD tutorial we'll use the features:
1. Extrude
Definition: Creates the primary solid shape. How it works: You sketch the profile of your bracket (usually an "L" shape or a "T" shape) and pull it into a solid block. Best for: Creating the main load-bearing walls or "skeleton" of the part.
2. Rib
Definition: Creates a thin wall or support web from an open sketch curve. How it works:
The Superpower: Unlike Extrude, you do not need to draw a closed shape (like a triangle). You simply draw a single diagonal line floating between two walls.
The Action: The Rib tool automatically extends that line down and sideways until it hits the solid walls, creating a perfect support web. Best for: Adding stiffness to brackets or plastic parts to prevent them from bending, without adding unnecessary weight.
3. Mirror
Definition: Creates a symmetrical copy of a Feature. How it works:
Efficiency: Instead of drawing ribs on both sides of a bracket, you model them on the Left side only.
Action: You select the Rib Feature in the timeline and the Center Plane. Fusion instantly duplicates the support structure to the Right side. Best for: Symmetrical parts. If you later change the thickness of the original rib, the mirrored one updates automatically.
4. Chamfer
Definition: Cuts a flat angle (bevel) on sharp edges. How it works: Removes the razor-sharp 90° corners. Best for:
Safety: Making the bracket safe to handle (deburring).
Clearance: Removing material so the bracket fits into a tight corner (e.g., clearing a weld bead on a wall).
All dimensions are in mm/g/s/ISO
