3D Exercise 63

Exercise 63

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. Best for: Creating the main "Master Model" block before you start cutting it up.

2. Revolve

Definition: Creates a solid by rotating a profile around an axis. How it works: Spins a profile 360° (or less) around a center line. Best for: Creating cylindrical parts like handles or knobs that you might later want to split in half.

3. Chamfer

Definition: Cuts a flat, angled bevel on an edge. How it works: You select an edge and define a distance. Best for: preparing edges for assembly (so parts slide together) or for aesthetic "finished" looks.

4. Offset Plane (Construction)

Definition: Creates a plane parallel to an existing face at a specific distance. How it works: Creates a floating surface to sketch on or to use as a cutting tool. Best for: Positioning the "knife" that you will use to cut your body in half.

5. Split Body

Definition: Cuts a single solid body into two separate bodies. How it works: You select the Body to Split (your part) and the Splitting Tool (a plane, a sketch line, or a surface). Fusion slices the object. You now have two distinct objects in your browser (e.g., "Body1" and "Body2"). Best for: Turning a solid designs into a 2-part enclosure (Top Case and Bottom Case) or slicing a model to make it 3D printable.

6. Combine

Definition: Performs boolean operations between two or more bodies. How it works:

• Join: Merges multiple bodies into one.

• Cut: Uses one body to remove material from another.

• Intersect: Keeps the overlapping volume. Best for: Creating "Interference Fits." For example, if you have a Peg and a Block, you can use Combine (Cut) to subtract the Peg from the Block, creating a perfectly shaped hole.

7. Remove (vs. Delete)

Definition: A "Soft Delete" that removes a body from the workspace but keeps the operation in the parametric timeline. How it works:

• Delete (Keyboard Key): Destroys the history. If you referenced that body earlier, your timeline breaks (Yellow/Red errors). Avoid this.

• Remove (Feature): You right-click a body in the browser and select "Remove." Fusion adds a "Remove Feature" icon to the timeline. It tells the software "Calculate everything up to this point, then hide/remove this object." Best for: Getting rid of "Tool Bodies" (like a cutter you used in a Split or Combine operation) that you no longer need to see, without breaking your design history.
