I am looking for a way to create superellipses in autocad. I found and arx routing online which says it works for version2000, but when I try to run it on ADT2006 it says it is incompatible with this version of AutoCad. I can not even speak with confidence that this routine would work but does any one know how to convert an old arx routine to a new one. Even better does anyone have a reliable tool to generate superellipses.
