3D Exercise 53

Exercise 53

In this CAD tutorial we'll use the features: 

1. Revolve (Solid)

Definition: Creates a 3D solid object by rotating a sketch profile around a center axis. How it works: You need two things: a Profile (like half a vase) and an Axis (a center line). Fusion 360 spins the profile 360° (or a specific angle) to create the shape. Best for: Cylindrical or spherical objects like chess pieces, wine glasses, or wheel rims.

2. Thread

Definition: Applies a thread texture or physical thread geometry to a cylindrical face. How it works: You select a cylinder (like a bolt or a hole). You can choose standard sizes (e.g., ISO Metric M10).

• Cosmetic (Default): Looks like a thread but is just a picture (saves computer power).

• Modeled: Physically cuts the spiral groove into the 3D geometry (essential for 3D printing). Best for: Creating screws, bolts, and threaded lids.

3. Chamfer

Definition: Bevels the edges of a solid body, usually at a 45-degree angle. How it works: You select an edge, and the tool cuts a flat slope. Best for: "Breaking" sharp corners so they aren't dangerous, or creating a "lead-in" so a bolt can easily slide into a hole.

4. Loft (Solid)

Definition: Creates a solid body that transitions smoothly between two or more different shapes (profiles). How it works: Unlike Extrude (which is just one shape pulled straight), Loft blends shapes. You can start with a Square on the bottom and Loft it up to a Circle on top. Fusion calculates the smooth transition in between. Best for: Complex handles, aircraft fuselages, or stylized furniture legs that change shape from top to bottom.

5. Sphere

Definition: A "Primitive" tool that instantly creates a perfect solid ball. How it works: You don't need to sketch anything. You simply click the Sphere tool, select a plane, click a center point, and type the diameter. Best for: Ball bearings, joints, or decorative tips.

6. Offset Plane (Construction)

Definition: Creates a new sketch plane parallel to an existing face or standard plane at a specific distance. How it works: Think of your default Top, Front, and Right planes as sheets of paper. An Offset Plane lets you create a new "floating sheet of paper" anywhere in 3D space. You select a reference (like the floor) and drag the arrow up to define where this new plane sits (e.g., 50mm high).
