The next step required is for you to enter length of the Arc, type a number into the box and hit the <Enter> key.
The final step required is for you to enter a Chord bearing, type a number into the box and hit the <Enter> key. (this is the bearing between the start point and end points of the Arc)
An ARC is constructed using the information entered.
