However, please feel free to leave constructive comments (see foot of webpage) and suggested improvements. I offer no support should these routines or commands not function as you expect. You're welcome to download, use, copy, amend, and adapt these files, but at your own risk.
Therefore I assume these lisp routines will also work on AutoCAD, but as I don't have access to AutoCAD I cannot confirm this These free lisp routines were tested using CorelCAD 2013 which accepts AutoLisp. Please find below a list of CAD lisp routines which I have written to automate common UK road design tasks when using CAD programs such as AutoCAD or CorelCAD
