Tony Hotchkiss, Ph.D., P.Eng., is a professor of CAD/CAM/CAE at the State University of New York College at Buffalo and a former Cadalyst contributing editor. He wrote Cadalyst's popular "AutoLISP Solutions" column through December 2008. "AutoLISP Solutions" tutorials have been tested to function with the version of AutoCAD that was current at the time the tutorial was published. Specific LISP routines may or may not function with other versions of AutoCAD, and Cadalyst staff cannot provide technical support in the event a routine does not function. Peer support for AutoLISP-related problems may be available via Cadalyst's Hot Tip Harry Discussion Forum at www.cadalyst.com/forums; users are encouraged to post requests there.
