When you run Blender you are presented with Blender's Graphical User Interface (GUI) which,

by default, displays an arrangement of panels (windows) for working in 3D Modeling and

Animation.

This arrangement constitutes what is termed the General Workspace. To work with the Grease

Pencil for 2D Animation you change this arrangement to the 2D Animation Workspace. Before

making this change it is advantageous to explore the Grease Pencil as it presents in the default

General 3D Workspace.

The Blender 3D Interface – Version 2.91.0

To explore the Grease Pencil you must have an understanding of the arrangement of controls in

the General screen arrangement (see Chapter 1).
