3D Exercise 51

Exercise 51

In this CAD tutorial we'll use the features: 

1. Extrude

Definition: Adds depth to a 2D sketch profile to create a 3D solid body. How it works: You select a closed sketch (like a circle or square) and pull it into 3D space. You can pull it to add material (Join), remove material (Cut), or create a brand new object (New Body). Best for: Creating the base shape of almost any design, turning flat drawings into blocks, cylinders, or walls.

2. Shell

Definition: Hollows out a solid body to create thin walls. How it works: Instead of manually modeling the inside of a box, you take a solid block and tell Fusion 360 to "scoop it out." You can leave it closed (like a hollow egg) or remove specific faces (like an open box) while defining a uniform wall thickness. Best for: Quickly creating containers, vases, or plastic casings for electronics without drawing the internal geometry.

3. Fillet

Definition: Rounds the sharp edges of a solid body. How it works: It removes material from outside corners to make them round, or adds material to inside corners to make them smooth. You select the edge and specify a radius (e.g., 5mm). Best for: Ergonomics (making handles comfortable), strengthening parts (removing stress concentrations at corners), and aesthetics.

4. Coil

Definition: Creates a spring-like or spiral primitive solid. How it works: This is an automated "Sweep." You define the diameter, the number of revolutions (turns), and the height. Fusion generates the helix automatically without you needing to draw the complex path manually. Best for: Modeling compression springs, custom threads that aren't standard sizes, or heating elements.

5. Emboss

Definition: Raises or recesses a sketch profile onto a face, even if that face is curved. How it works: Unlike Extrude (which moves in a straight line), Emboss "wraps" your sketch onto the surface like a sticker before pushing it in or out. Best for: Putting logos or text onto curved surfaces (like a text on a cylinder) or creating grip patterns on a round handle.
