Applying the bending and stretching deformation rule
In Figure 3.1, you can see an elbow joint. This is one of the most common joints modeled on a mesh being deformed by an armature. Deformation refers to the bending or stretching of a mesh and is used to describe any shifting of the mesh after the mesh is finished.

Our first deformation rule is that the edges of our grid need to be parallel to the axis of deformation. That is a bit of a mouthful, so we are going to break it down with a few examples. In Figure 3.2, we have a plane that has been bent around the y-axis.

Go through the following steps to make this shape:
- First, start by pressing Shift + A.
- Add a plane from the mesh dropdown.
- Then, go into Edit Mode.
- Click on RMB, and select Subdivide.
- In the bottom left of the Viewport, the Subdivide tab will appear ...
