In this CAD tutorial we'll use the features:
1. New Sheet Metal Rule (The Foundation)
Definition: Defines the physical properties of the metal you are using. How it works:
The Problem: You cannot just "draw" sheet metal. Steel bends differently than Aluminum.
The Solution: You go to the Sheet Metal Rules library and create a New Rule. You define:
Thickness: e.g., 1.5mm.
K-Factor: How much the material stretches when bent (usually ~0.44 for steel).
Bend Conditions: The default radius for every bend (usually thickness * 1). Why it matters: If you change this rule later (e.g., from Aluminum to Stainless Steel), your entire 3D model updates automatically.
2. Extrude (Base Flange)
Definition: Creates the initial flat piece of metal. How it works:
The Difference: In the Sheet Metal workspace, the Extrude tool is smarter. You select a closed sketch profile, and it automatically applies the thickness from your Rule. You don't type a distance. Best for: Creating the base plate or "floor" of your enclosure.
3. Flange
Definition: Creates bent walls extending from edges. How it works:
The Magic: You click an edge of your base plate and drag an arrow up. Fusion automatically adds the metal wall and the correct Bend Radius in the corner based on your Rule.
Chaining: You can select multiple edges at once to create a box instantly. Best for: Building vertical walls and lips.
4. Mirror
Definition: Creates a symmetrical copy of features or bodies. How it works:
Efficiency: Sheet metal parts are often symmetrical. You model the complex flanges and cuts on the Left side.
Action: Select the Flange Features (from the timeline) and the Center Plane. Fusion generates the Right side.
Crucial Note: In Sheet Metal, it is often better to mirror Features (the flange actions) rather than Bodies so they join properly at the seams.
5. Fillet (Corner)
Definition: Rounds off sharp corners on the flat pattern. How it works:
Safety: Sheet metal creates razor-sharp corners (burrs) when laser cut.
Action: You apply a 2-Corner Fillet to the sharp edges of your flanges.
Aesthetics: It makes the part look finished and safe to handle.
