In this CAD tutorial we'll use the features:

Creation and Modification Tools

Extrude: This feature allows you to take a 2D sketch and add thickness to it in the third dimension. It's the most common command for building a solid part from a sketch.
Sweep: This command creates a 3D solid by extruding a 2D closed profile sketch along a 2D or 3D path sketch. The unique feature of Sweep is that the closed profile can be tapered or twisted as it extrudes along its path, allowing for complex, curved geometry.
Fillet: The Fillet feature creates a rounded internal or external face on the part. It's used to smooth out sharp edges.

Patterning and Utility Tools

Circular Pattern: This feature duplicates faces, features, bodies, or components and arranges them in an arc or circular pattern. It's a quick way to create multiple, evenly spaced copies around a central point.
Move/Copy: This command moves the selected face, body, sketch, or construction geometry a specified distance or angle. It's used to precisely position or duplicate existing geometry.
Combine: This command performs boolean operations between solid bodies. This means you can use it to join multiple bodies together, cut one body from another, or find the intersecting volume between them. The tutorial specifically mentions using Extrude to make two bodies and then using Combine to join them.

Construction Geometry

Plane Along Path: This command creates a construction plane normal to an edge or sketch profile. The plane is perpendicular to the path at the selected location and is crucial for creating the initial sketch profile needed for the Sweep command.

All dimensions are in mm/g/s/ISO

Step 1

Create Sketch 1 in the Top Plane

Step 2

Create Sketch 2 in the Front Plane, use the circular Pattern To make 4 profiles

Step 3

Use the Sweep Feature, The profile is the Sketch 2 and the path is the sketch.

Twist Angle -405 degrees

Step 4

Create a new Sketch in the front plane (sketch 3)

Step 5

Use Sweep in 1 retangle , and the path is the sketch 1, twist angle -405 deg

Step 6

Use Sweep in 1 retangle of the sketch 3 , and the path is the sketch 1, twist angle -405 deg

Step 7

Create a new Sketch in the front plane (Sketch 4)

Step 8

Extrude the sketch 4 , 1mm

Step 9

Use the Circular Pattern in the body 7

Distribuition Partial

Angle 180 Deg

Quantity = 30

Step 10

Use the Combine Feature , Target Body is the body 5 and the tool Bodies is the yellows bodies in the photo bellow. In the Operation select Intersect and select create a new Component.

Step 11

Add Fillet to the component 1, fillet is 0,5mm

Step 12

Create a New Plane along the Path , the path is the sketch 1, distance type Physical, distance 3mm.

Step 13

Create a sketch (sketch 5) in the new plane, a circle in the mid point with 30mm of diameter.

Step 14

Extrude the Sketch 5 , 1 mm

Step 15

Use the circular Pattern in the body of the last extrusion.

Setp 16

Use the Combine to combine the step 15 and Step 6, the operation is Intersect, and creat a new component.

Step 17

Add Fillet to component 2

Step 18

Combine the bodies and the components

Step 19

Use the Move and Copy Feature in the component 3.

The angle 180 deg, and select create Copy.

Here we finish our Exercise.
