This command draws a construction line midway between 2 points and perpendicular to them. So for example if the 2 points indicated were the end points of an existing line then the new construction line would be drawn through the mid-point of that line at 90 degrees to it.

Select the Perpendicular Line button button and the command prompt reads:

Give Point:

Use any of the snaps and input options  to indicate 2 points. A line three times the width of the current Page is drawn. This is drawn on a layer called 'Constructions' which is set to 'blue' by default.
