In this tutorial, we'll learn how to model and texture a trombone.
We'll be using a [Curve Point] to model a part of the mesh.
To use the Curve Point, you need to activate an Add-on called 'Add Curves: Extra Objects' that can be found under [File - Preferences - Add-ons].
The starting .blend file used in this tutorial can be downloaded from here.
