Cursor Lock Functions
You can lock the cursor as a ruler by selecting a lock function from the context-sensitive menu or by using keyboard commands. The ruler is set to pass through the local origin, i.e., the point selected last.

Perpendicular | T | The direction perpendicular to the line nearest to the cursor. | Move the cursor over the line. |

When you have selected the ruler function and then move the mouse, the cursor will move in the direction of the ruler. When using the ruler, the cursor functions as a snap point with which you can select a point in relation to the reference point. The movement direction of the snap point is perpendicular to the direction of the ruler.
