Kent Cooper created this update to an AutoCAD tip submitted more than a decade ago. The original tip allowed you to perform a single fillet with radius zero, after which it restored the original radius value to the built-in Fillet command. Kent’s version allows for the same functionality, except you can perform as many fillets as you need with a zero radius. Load the LISP file, then type in the command FZ, pick two entities to fillet with a zero radius, and then keep going as long as you need to. Press Enter to end, and the original radius value for Fillet will be restored. An error handler resets the value in case you press Esc also.
