I wrote this because I needed to edit an alignment and just wanted to recreate it from a new polyline.
WARNING save your drawing first you could lose you alignment data WARNING
Also spirals will be lost (converted to arcs and lines)
makepl - to make a polyline from the alignment (you can already easily do this by offseting the alignment)
remakeal - to remake the alignment from a polyline
by remaking the alignment from the polyline hopefully labels wont be lost.
Hope this makes sense.
