In this CAD tutorial we'll use the features:
1. Revolve
Definition: Creates a solid by spinning a sketch profile around an axis. How it works: You draw half of the object’s profile and a center line. Fusion spins it to create the 3D volume. Best for: Creating the starting shape for cylindrical objects like bottles, pods, or cases.
2. Shell
Definition: Hollows out a solid body. How it works: You select the body (and optionally a face to remove, like the top). Fusion removes the internal material, leaving a wall of a specific thickness. Best for: Turning your solid "Revolved" block into a hollow container or housing.
3. Split Body
Definition: Cuts a single solid body into two separate, independent bodies. How it works: You need a "Splitting Tool," which can be a construction plane, a sketch line, or a surface. When you execute the split, "Body 1" becomes "Body 1" and "Body 2." Best for: Manufacturing. You model the product as one piece first to get the shape right, then Split it into a "Lid" and a "Base" later.
4. Offset Face
Definition: Moves a solid face in or out, adjusting the volume of the part without changing the original sketch. How it works: You select a 3D face and drag the arrow.
The Tolerance Trick: If you 3D print a lid and a box that are the exact same size, they won't fit. Use Offset Face to push the face of the lid inwards by -0.2mm. This creates the physical gap (tolerance) needed for the parts to slide together. Best for: Adjusting fit and clearance after you have modeled the geometry.
5. Extrude
Definition: Pushes or pulls a profile to create depth. How it works: Standard creation of solid geometry. Best for: Adding details like a latch, a button, or a lip to the edges you just exposed with the Split Body tool.
6. Combine
Definition: Performs boolean operations (Join, Cut, Intersect) on bodies. How it works:
Join: Glues bodies together.
Cut: Uses one body to subtract from another. Best for: If you modeled a separate handle or a mounting boss, use Combine (Join) to fuse it to your main Shell.
7. Fillet
Definition: Rounds off sharp edges. How it works: Applies a radius to smooth transitions. Best for: Applied at the very end to make the split lines smooth to the touch.
