Yes. Lines are segmented by a small diamond shape. The shapes enable you to manipulate the thickness and length of a line.

  1. To increase the length of a line vertically, scroll over the diamond and a vertical arrow will appear. Then drag the line to the desired length. 

  2. To increase the width of the line, scroll over a segment diamond and a horizontal arrow will appear. Drag the arrow horizontally. 


LegiTip: IIf the  vertical and horizontal arrows don't appear when you scroll over the diamond, save the system and then try again.
