in this video tutorials SLK''s Tut's presents the setting out of road or railway line curve by perpendicular offsets from tangent lines method.
the concept of this method is so straight like below.
the 1st thing we do is to locate the curve points by determining the tangent length of the curve. then we divide the tangent line with some intervals and take perpendicular offsets from tangent line. after this we join the ends of all offsets which make a nice and smooth curve....
the detail calculation is in the video. lets watch the video to learn the curve setting out or marking....
