3D Exercise 52

Exercise 52

In this CAD tutorial we'll use the features: 

1. Extrude

Definition: The most fundamental tool that gives depth to a 2D sketch, turning it into a 3D solid. How it works: You select a profile (closed sketch region) and pull it. You can add material (Join), remove material (Cut), or create a New Body. Best for: Creating the primary block of your part or cutting simple shapes out of it.

2. Circular Pattern

Definition: Duplicates features, bodies, or faces in a circular arrangement around a central axis. How it works: Instead of modeling a wheel spoke 5 times, you model it once. Then, you select that feature, choose a center axis (like the center of the wheel), and type "5". Fusion creates the other 4 perfectly spaced. Best for: Creating wheels, gears, showerhead holes, or flanges with bolt circles.

3. Fillet

Definition: Creates a rounded, smooth transition on an edge. How it works: It removes material from an outside corner (to make it round) or adds material to an inside corner (to reinforce it). Best for: Removing sharp edges that could cut a user, strengthening parts (stress relief), and improving aesthetics.

4. Chamfer

Definition: Creates a flat, angled bevel on an edge (usually 45°). How it works: Unlike a Fillet which is round, a Chamfer cuts a straight angle. You select the edge and define the distance or angle. Best for: "Breaking" sharp edges so parts slide into each other easily (assembly aid), or for a specific machine-part look.

5. Mirror

Definition: Creates a reflected copy of a feature, body, or component across a plane. How it works: If you are designing something symmetrical (like a car or a game controller), you only model the left half. Then, you use Mirror to generate the right half perfectly. Best for: Saving time on symmetrical objects. Never model the same thing twice!

6. Hole

Definition: An advanced tool specifically for creating drill holes, threaded holes, and counterbores. How it works: Don't confuse this with Extrude Cut. The Hole tool lets you select standard industry sizes (e.g., "M6 screw"), add threads, and shape the top of the hole (Countersink for flat-head screws) automatically. Best for: creating mounting points for screws and bolts. It ensures your hole is the exact standard size needed for the hardware.
