Hi, I`m using AutoCad 2007 and have this problem:I have a road with many points in the axis and lines at the left and the right edge. I need the perpendicular distances from every point to the left and the right edge. I`m trying to write a script but i can`t formulate how to be biult the perpendiculares.

Such functions are quite difficult in the plain AutoCAD. This can be done automatically in AutoCAD Civil 3D.
