In this CAD tutorial we'll use the features:
1. Extrude (Boss/Base or Cut)
This is often the most used command in 3D modeling. It takes a 2D sketch and pulls it into the third dimension to create a solid body or remove material.

Boss/Base Extrude: Adds material by pulling a sketch profile linearly (e.g., turning a circle into a cylinder).

Cut Extrude: Removes material by projecting a sketch profile through an existing solid (e.g., drilling a hole).

2. Mirror
The Mirror command creates a symmetrical copy of features, faces, or entire bodies across a specified plane or planar face.

Efficiency: It is essential for symmetric parts. Instead of modeling both the left and right sides of a car steering wheel, you model one half and mirror it across the center plane.

Types: You can usually mirror 2D sketches (sketch entities) or 3D features (solids/surfaces).

3. Fillet
Fillets are used to round off sharp edges or corners of a model.

Function: It creates a rounded internal or external face along one or more edges.

Engineering Purpose: Aside from aesthetics and safety (removing sharp edges), fillets are crucial for reducing stress concentrations in mechanical parts, making them stronger and easier to manufacture (molding or machining).

4. Rib
A Rib is a specialized feature designed to add structural support to a part without adding excessive weight or material thickness.

Geometry: It creates a thin-walled support structure (usually triangular or rectangular) between two perpendicular surfaces.

Usage: You sketch a single line representing the cross-section, and the software automatically fills the material to the surrounding walls. It is commonly used in plastic injection molding designs to strengthen walls and bosses.
