Bevel Level (its almost like a boss battle title)

Beveling gives segments to the edges of your shape and can vary in the way it looks depending on if you edit the segments (top row) or the offset (bottom row).

Beveling also affects how a shape will render when smooth. Without any beveling the shape will render like the first rectangle in the top left corner and look like a cigar shape. Once you bevel the shape will retain its original form better and you can decide how the shape will look smooth rendered.

 

When beveling you can bevel different parts of the shape  in order to get different outcomes when the shape is smooth rendered. You can bevel all the sides, the ends, or the sides. (left to right in above picture) And when rendered these will give you the shapes below.
