Swept Boss or base feature is very useful tool, which helps to create 3d product design parts. Some of the application examples are create spring model, complex hollow pipes, air conditioning ducts, curved rods, tubes, twisted parts etc.

Then select the one of the start point of the line sketch, where you want to create closed profile as “First Reference”. In this example, I select the left end of the line sketch as “First Reference”.

Additional Info: Swept Property Manager

Check on the Swept property manager and you could get different options. I also explain the swept property manager and how it effect on your example model.

Profile and path: In this section, you need to select the closed profile and open or closed path as you need to sweeps through it to make the model. First select the closed profile and then shows the path as you need to sweeps the profile through it.

Options: The options contain two main sections such as Orientation/twist type and Path alignment Type.

The orientation type contains different sub-options are Follow path, Keep normal constant, Follow the path and 1st guide curves, Follow the 1st and 2nd guide curves, Twist along path and Twist along path with normal constant.

The path alignment type controls the alignment of the path. It contains sub-options such as none, Minimum twist, Direction Vector and all faces.

Best idea to study these options is try on your base model.

Thin Feature: Using the Thin feature in Swept boss or base property manager, you can create the hollow rectangular duct in this example. Select the thin feature and enter the thickness. You can use the Swept Cut tool for creating this type of hollow rectangular pipes.
