I need programming help!!!! If you know any young CAD-sters who want to learn AutoLISP, send them my way! The pay is heavenly.

You will find that in short order the vehicle does a jack-knife and heads forward. Simply turn your vehicle around at the start of the path. I am intrigued by your method of achieving reverse modeling, and I hope it is an encouragement to others. Again, MUCH THANKS for a GREAT routine.So the mirroring was a perfect solution given that we were able to see that there was enough room to back up for a few yards then straighten out and move forward again. In other words, we considered the last instance of the vehicle to be the point at which the vehicle stopped completely (on a curve, no trailer), whereupon the steering wheel would be turned all the way in the opposite direction before reversing. To make a long story short, we accomplished the reverse modeling which was required for our purposes by simply mirroring the entire generated path along the front and rear midpoints of the last instance of the vehicle generated by the routine. So, as already commented upon, that would be a nice addition as well.

The other day, I taught one of our engineers how to use the the routine and he asked me if there was a way to model a path in reverse.

However, having the routine draw polylines along the overhang paths would also be nice.

With the current release, overhang paths can easily be seen by having the routine plot a whole bunch of vehicles along the path.

No big deal at all, but this might be something to consider when tweaking future releases. However, for a reverse turn to the left, the right front tire becomes the outermost tire and the radius of the path of the left front tire has to be reduced by the distance between the two front tires to approximate the radius. 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.
