In this CAD tutorial we'll use the features:
1. Rib
Definition: Creates a thin wall or web support from an open sketch curve. How it works:
The Magic: You do not need to draw a closed triangle and extrude it. You just draw a single diagonal line floating in the air between two walls.
The Action: The Rib tool automatically extends that line down and sideways until it hits the solid walls, filling the gap with a web of material. Best for: Adding structural strength (stiffeners) to L-brackets or plastic enclosures without adding excessive weight.
2. Mirror
Definition: Creates a symmetrical copy of a feature or body. How it works:
Efficiency: Instead of drawing two separate ribs, you model one. Then you select the Rib feature and the center plane to copy it to the other side. Best for: Symmetrical reinforcement.
3. Extrude
Definition: Creates the main solid shape. How it works: Creates the base L-bracket or housing walls. Best for: The primary geometry that the ribs will attach to.
4. Fillet
Definition: Rounds off internal corners. How it works:
Structural Integrity: A sharp corner where a Rib meets a Wall is a weak point (stress concentrator). Adding a fillet here spreads the load and prevents the part from snapping. Best for: "Blending" the rib into the main body.
5. Chamfer
Definition: Cuts a flat angle on an edge. How it works: Removes the sharp outer edge. Best for: Aesthetic finishing or creating a "lead-in" for bolts.
6. Hole
Definition: Creates mounting points. How it works: Drills through the bracket base. Best for: Bolt holes to mount the bracket to a wall.
All dimensions are in mm/g/s/ISO
