In this CAD tutorial we'll use the features: 
1. Sheet Metal Extrude (Base Flange)
Definition: The starting point for most sheet metal parts. It turns a sketch profile into a flat plate of a specific thickness. How it works: Unlike a standard solid Extrude where you type "5mm," here you select a Sheet Metal Rule (e.g., "Steel (mm)"). Fusion applies the thickness automatically based on that rule. Best for: Creating the initial flat plate or "Base Flange" from which you will bend up walls.

2. Flange
Definition: The most important tool in this workspace. It creates a wall (flange) extending from an existing edge, complete with a bend radius. How it works: You select an edge of your base plate and drag an arrow up. Fusion automatically adds the material and the bend relief (the little cuts in the corners) based on your K-factor rules. Best for: Creating the vertical walls of a box, bracket, or enclosure.

3. Unfold
Definition: Temporarily flattens a bent part so you can work on it as if it were a flat sheet. How it works: You select a stationary face (the one that stays put) and the bends you want to flatten. Why use it? If you need to cut a slot that wraps across a bend (going from the front wall, over the corner, to the top wall), you cannot do that easily in 3D. You Unfold it, cut the slot across the flat area, and then Refold. Note: Do not confuse this with "Create Flat Pattern." Unfold is for modeling; Flat Pattern is for manufacturing.

4. Refold
Definition: The partner to the "Unfold" tool. It snaps the part back into its 3D bent shape. How it works: After you finish cutting your complex holes in Unfold mode, you click Refold. The walls bend back up, and your cuts wrap perfectly around the corners. Best for: Returning to the finished view after performing cross-bend operations.

5.Chamfer
A chamfer is a manufacturing and design detail that creates a straight, angled cut across a sharp edge or corner.
• Function: It removes material to produce a beveled edge where two faces meet.
• Result: Replaces a sharp corner with an angled surface.
• Why it's used:
o Manufacturability: Eases assembly and prevents damage to threads or internal features.
o Aesthetics: Provides a clean, modern look.
o Safety: Removes sharp corners for better handling.
