Always add overline for page titles. Should be:

****
Bend
****

It's a bit redundant to have a "Description" header - we assume that the text immediately at the top is a description of the feature.

Lines should be a maximum of 120 characters long. Most decent text editors can show you the column number (usually in the bottom corner) or even display a ruler at the 120 character mark.

No need to make this italic, best keep it consistent with the rest of the docs.

It's better to avoid writing these sort of mini tutorials - this section could be placed above in the description and rephrased shorter to something like: "Common usage is to align the view and place the cursor at the pivot of the arc, then bend it... this can be useful for..."

There's nothing wrong with this, but just to note that we can use a special 'hint' directive that has some fancy formatting:

.. hint:: You can turn the bend angle through multiple rotations potentially forming a spiral shape.
