Point along perpendicular This is very handy when you wish to ‘square off’ from a particular point. In other words, create a line at a 90° angle from a point. Click on the point where you need to square off and drag around to another. A box will pop up where you may enter a formula or length of the line, change the label, use the arrows or enter the degrees for the ‘square off’, change the line type and change the color of the line. Once again, you can click apply to check that it is doing what you want before clicking ‘Ok’ to accept the instruction and close the box.
