3D Exercise 103

3D Model 103
Exercise 103

In this CAD tutorial we'll use the features: 

1. Extrude

Definition: The primary tool for creating the main solid shape. How it works: Creates the base cylinder or disk. Best for: Creating the raw "stock material" (the metal disk) before you start machining details into it.


2. Chamfer

Definition: Cuts a flat angle (bevel) on sharp edges. How it works:

  • The Difference: Unlike "Fillet" (which makes edges round/soft), Chamfer makes them flat/angular (usually 45°).

  • The Look: It gives parts a "Machined" or "Industrial" look rather than a "Molded Plastic" look. Best for:

  • Deburring: Removing razor-sharp edges from a metal part so it is safe to handle.

  • Assembly: Helping a part slide into another part (a "lead-in").


3. Hole

Definition: Creates precise standard drill holes. How it works: It uses industry standards (like ISO or ANSI) to cut the correct size for bolts. Best for: Creating the mounting holes (Lug holes) or ventilation holes.


4. Circular Pattern

Definition: Duplicates features around a center axis. How it works:

  • Efficiency: You drill one hole. Then you tell Fusion, "Copy this hole 5 times around the center."

  • Result: Perfect spacing without doing any math. Best for: Bolt circles on flanges or ventilation holes on a brake rotor.



All dimensions are in mm/g/s/ISO
