This free lisp is useful while working with Land Survey Drawings. If you have surveyed either side of the road and if you wish to mark the centre of the road, using this free lisp it can be done quickly. Lisp will prompt you to select a line segment of the polygon on either side, once you select segments, a centre line is drawn. Please note that if both the side of the road is not parallel along the alignment, then offset command will not give the exact centre line and hence this lisp can be used to draw centre line.
