Drawing center lines in autocad

For AutoCAD: If the centerline is a 2D element and all the points are at the same elevation, make any centerline segments into a polyline to make what you are doing a lot easier. To make connecting lines and curves into a polyline, select the segments and use the JOIN command to create a polyline so they are now one continuous line. I don't quite understand what you want, either -- post an image or sample drawing. It's just a question of money and time if you want to use a product like Civil 3D which can do that already or you try to develop it by yourself.

In AutoCAD and later versions with Centerline command you can creates centerline geometry of a specified linetype in association with selected lines and polylines. Does that mean that the distance s are different at different chainage locations along the same track?

Your use of "distance" in the singular is probably what has led people to suggest using OFFSET and Civil3D's Create-Offset-Alignment, but those would not do if there are different distances -- they will only make something that is the same distance from the source object everywhere. If you want to make it automatic, you must have some kind of electronic documentation. In what form do you have the information?

A list of pairs of chainage values with offset distances? One list of chainage values and another list of offset distances in the same order? A text or spreadsheet file of some kind? Something else? Is the distance at each chainage location always the same on both sides of the track-center route?

In the situation illustrated, I can imagine that it might not be, but then you would need a separate set of data for each side. Offset Alignment.
