3D Exercise 75

Exercise 75

In this CAD tutorial we'll use the features: 

1. Pipe

Definition: A productivity tool that instantly creates a tube or rod along a sketch path. How it works: It replaces the slow process of "Sketch Circle + Sweep." You simply draw a single line (straight or curved). Then, select the Pipe tool and click that line. You can choose:

• Section: Circle, Square, or Triangle.

• Hollow: Check this box to make it a tube (like a straw) instead of a solid rod. Best for: Roll cages, furniture frames (chairs/tables), exhaust manifolds, or the rim of a steering wheel.

2. Extrude

Definition: The standard tool for creating solid geometry from a sketch. How it works: You select a profile and give it thickness. Best for: Creating the rigid parts that connect to your pipes, such as a central hub, a mounting plate, or a seat base.

3. Circular Pattern

Definition: Duplicates features or bodies in a circle around a center axis. How it works: You model one instance of an object (like one leg of a stool or one spoke of a wheel). Then:

1. Select the Object (the Pipe leg).

2. Select the Axis (the center vertical line).

3. Enter the Quantity (e.g., 3 or 4). Best for: Radial symmetry. It saves you from drawing and piping every single leg manually.

4. Chamfer

Definition: Cuts a flat, angled bevel on an edge. How it works: Removes the corner at a 45° angle (usually). Best for: The ends of the pipes or tubes. If a pipe is meant to be welded or inserted into a socket, a chamfer helps it align and fit.

5. Fillet

Definition: Rounds off sharp edges. How it works: Creates a smooth radius. Best for:

• Weld Beads: Adding a fillet where a Pipe meets an Extruded plate simulates a weld.

• Touch: Removing sharpness from the extruded parts so they don't scratch the user.
