In this CAD tutorial we'll use the features:
1. Revolve
Definition: Creates a cylinder or ring by spinning a profile. How it works: You sketch the cross-section of the bearing housing or pivot point. Best for: The "Hubs" or "Bosses" where the part rotates or holds a bearing.
2. Extrude
Definition: Pulls a sketch into a solid shape. How it works: Creates the structural arm that connects the hubs together. Best for: The main body or "beam" of the part.
3. Fillet
Definition: Rounds off concave intersections. How it works:
The "Weld": When you connect a square Arm (Extrude) to a round Hub (Revolve), the connection is sharp and weak.
The Solution: Apply a large fillet here. It acts like a "weld bead," smoothly blending the two shapes together to prevent cracking under stress.
4. Mirror
Definition: Creates a symmetrical copy. How it works:
Efficiency: Automotive parts are often symmetrical. You model the Left arm, then Mirror it to create the Right arm perfectly. Best for: Ensuring the part is perfectly balanced without doing double the work.
5. Combine
Definition: Merges separate solid bodies into one. How it works:
The Problem: After mirroring, you often have 3 separate pieces: The Central Hub, the Left Arm, and the Right Arm.
The Solution: Select all three bodies and use Combine (Join). This welds them into a single, manufacturable piece of metal. Best for: Cleaning up multi-body assemblies into a single part.
6. Hole
Definition: Drills precise mounting points. How it works: Adds the bolt holes for mounting brake calipers or ball joints. Best for: Final machining details.
All dimensions are in mm/g/s/ISO
