In this CAD tutorial we'll use the features:
1. Extrude
Definition: The primary tool for creating 3D geometry from a 2D sketch. How it works: You select a closed sketch profile and pull it into 3D space.
Solid Mode: Creates a solid block.
Surface Mode: If you are in the Surface tab, "Extrude" creates hollow walls (like a ribbon) following the sketch lines, without a top or bottom cap. Best for: 90% of all 3D modeling tasks starts here—creating walls, blocks, and cuts.
2. Fillet
Definition: Rounds the sharp edges of a body. How it works: You select an edge, and Fusion 360 replaces the sharp corner with a smooth arc tangent to the adjacent faces. Best for: Removing sharp edges for safety, aesthetics, or "Stress Relief" (sharp internal corners are where parts usually crack; fillets make them stronger).
3. Plane Through 3 Points (Construction)
Definition: Creates a construction plane defined by selecting three specific points in space. How it works: In Geometry, any 3 non-linear points define a plane. Fusion 360 uses this rule. You click three points (vertices, sketch points, or work points), and a plane appears that connects them all. Best for: Creating a sketch plane on an odd angle where you don't have a flat face to click on. It is commonly used to slice corners off a cube or to build geometry connecting three disparate parts of an assembly.
4. Surface Offset
Definition: Creates a copy of an existing face or surface at a specified distance. How it works:
Distance = 0: It creates an exact copy of the face (useful if you want to copy a face from a solid body to start a new surface design).
Distance > 0: It creates a "bubble" or "skin" floating above or below the original surface. Important Distinction: Unlike "Thicken" (which makes a solid wall), Surface Offset just makes another paper-thin sheet floating in space. Best for: Creating internal clearances (e.g., making a phone case that is 0.5mm larger than the phone) or extracting geometry to use as a cutting tool.
All dimensions are in mm/g/s/ISO
