Catics - 3D02_03 Model — Exercise 98 - 3D02_03

In this CAD tutorial we'll use the features:

1. Revolve

Definition: Creates a 3D solid by rotating a sketch profile around a center axis. How it works: You sketch the cross-section (the side view sliced in half) and a centerline. Fusion spins it to create the solid. Best for: Creating cylindrical base shapes like hubs, axles, or rims.

2. Mirror

Definition: Creates a symmetrical copy of a body or feature. How it works:

Mirror Body: If you only Revolved the bottom half of a spool, use Mirror to create the top half instantly. This ensures both sides are mathematically identical.
Mirror Feature: If you cut a hole on the front face, use Mirror to cut the same hole on the back face. Best for: Reducing work. Never model the same thing twice if it is symmetrical.

3. Offset Plane

Definition: Creates a sketching canvas parallel to an existing face but at a specific distance away. How it works:

The Problem: You want to draw a detail on the "spoke" of your wheel, but the spoke is recessed inside the rim.
The Solution: Create an Offset Plane deep inside the rim to sketch on the correct level. Best for: Sketching on recessed surfaces or creating "floating" geometry.

4. Extrude

Definition: Adds or removes material. How it works:

Join: Add a mounting boss to your hub.
Cut: Cut a lightening hole through the offset plane you just created. Best for: Adding the specific details (holes, slots, keys) to your Revolved base.

5. Circular Pattern

Definition: Duplicates features around a center axis. How it works: You model one detail (like one bolt hole or one lightening cutout). Then you pattern it 5 or 6 times around the center. Best for: Bolt circles, spokes, and gear teeth.

6. Chamfer

Definition: Cuts a flat angle (bevel) on sharp edges. How it works: Select the edges of your bolt holes or the rim. Best for:

Assembly: Helping bolts slide into holes (the "lead-in").
Durability: Removing razor-sharp edges that would chip or cut the user.
