Sorry ,Tharwat, No offense.

It's not mine, just a little suggestion.

 

I find the source code at here:

Anyone get this lisp to work in Acad 2008 or before version. I get no error, but not working either. Steve

highflybird,

 

There is some function missing from your code namely "HH:ssPts:Sort" and "HH:ayOSMode"

 

Also since you are filtering polylines to a length of 2, this would means that it needs to be

exploded. ???

 

I also doubt very much that this code ad the one shown on the animation are the same.

Yes, the code is the same, but I had to modify it - to add missing subfunctions; to add POLYLINE option (ymg, yes I had to explode POLYLINE)...

 

Here is my version :

Good job!, but you are generous when you say the code is the same. :)
