Draft Constrain

To use constraining, press SHIFT while drawing.



In all tools that support constraining, you can force the next point to be constrained horizontally or vertically in relation to the last point entered. The vertical or horizontal constraining depends on where your mouse lies when you press SHIFT. If you are more north or south from the last point, it will be vertical. If you are more east or west, it will be horizontal. To change, just release SHIFT and press again at another location.
