With lofted boss and lofted cut, we are able to add or remove materials based on multiple cross-sections. Let's talk about them in more detail:

• Lofted boss: This adds materials by linking different cross-sections together. This includes the start and end of the shape. If we choose to, we can link these cross-sections with guide curves.
• Lofted cut: This removes materials by linking different cross sections together. This includes the start and end of the cut shape. If we choose to, we can link these cross-sections with guide curves.

These features are polar opposites: one adds materials while the other removes materials in the same way. The following diagrams illustrate these features: 

The preceding diagram shows a Lofted Boss, while the following diagram shows a Lofted Cut. Note that both features require at least two sketches if we wish to apply them. We can add as many sketches as we wish in order to define the sections:

Lofted boss and cut can provide us with a unique way of controlling how we add or remove materials compared to other features such as swept boss and swept cut and extruded boss and extruded cut. Now that we know what lofted boss and lofted cut is used for, we can start applying them. Let's start by applying a lofted boss.
