Since the path used by the routine is for the left front tire, turns to the right obviously just use the minimum turn radius for the outermost front tire as shown in AASHTO's Green Book. Templates proved to be useless so I did a search and found Turn.lsp. A couple of months ago I was trying to model a path for a rather complicated turn for a WB-62 which involved a bit of weaving with a reverse curve along the path. First of all, a GREAT BIG THANKS for this excellent LISP Routine.

Also, it would be nice to link up a DXF or DWG file with some blocks already defined. One enhancement would be to be able to go in reverse as the newer versions of AutoTurn can do. If you want to use the National CAD Standard then I would use something like C-ROAD-TURN-? or C-ALGN-TURN-?. I did get the script to draw a vehicle and place that along an alignment.
