In the next chapter, we will learn how to use some of those tools in the

modifiers section, where you will apply smoothing to 3D models and

several replication modes to use patterns for modeling.

Besides modifies, you will also learn how to work with rounded profiles

with the Spin tool, which will combine the use of an extrude with a

rotation. That increases the number of options to create 3D models in

Blender and give you more freedom to make complex objects.
