Free Lisp - Road Alignment Design

This free lisp is useful while working with Road Alignments. Just select any alignment in your drawing, this lisp will update many Road design details for all the curves. Lisp will assign Curve numbers to each curve in the order of alignment. It will find out Deflection Angle, Circular Radius, Transition Length, Starting Chainage, Ending Chainage and Circular Curve Length. It will just mark Transition Length as Zero. When you run the lisp it will ask for default speed, if you enter speed that value will be filled in attribute blocks of the entire curve. Later you may change transition Length and Speed, in case if you have values. This will be useful in Road Design.
