Creating Lines

Select the line tool from the Basic palette.

Select either constrained or unconstrained line
Constrained lines are drawn at 30∘45∘and 90∘angles. Unconstrained lines can be drawn at any angle.
*By pressing the shift key (⇧) while drawing a line in the unconstrained option, the line automatically becomes constrained.
