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.
