In this CAD tutorial we'll use the features:

📐 Extrude

Extrusion is one of the most common methods for turning a 2D sketch into a 3D solid model.

What it does: It takes a closed 2D sketch (a profile) and pushes or pulls it along a straight path (perpendicular to the sketch plane) to give it depth, creating a solid feature.
Result: The resulting shape is a prism or a block, depending on the complexity of the 2D profile.
Operations: Extrusions can be used to add material (extrude boss/base) or remove material (extrude cut/hole) from an existing solid body.

🔪 Fillet

A fillet is a feature used to round off sharp exterior or interior corners and edges of a 3D model.

What it does: It adds a rounded transition of a specified radius between two intersecting faces or edges.
Result: It replaces a sharp corner with a smooth, curved surface.
Why it's used:
- Aesthetics: Improves the appearance of a part.
- Stress Reduction: Distributes stress over a larger area, which is crucial in mechanical parts, preventing cracks from forming at sharp corners (where stress concentration is highest).
- Safety/Handling: Eliminates sharp edges for safer handling.
- Manufacturability: Eases molding and casting processes.

🦴 Rib

A rib is a thin, flat structure typically used to provide structural support to a part, increasing its strength and rigidity without adding excessive material.

What it does: It's a strengthening feature that connects a feature (like a boss or a wall) to a base or another wall.
Construction: It's usually created from an open or closed sketch that is extruded up to the next surface, often tapering slightly.
Result: It forms a brace or gusset, usually perpendicular to the walls it connects.
Why it's used: Ribs are common in plastic injection-molded parts and castings to prevent bending or warping under load while keeping the material thickness uniform for cooling and manufacturing purposes.
