I use Autocad Mechanical 2006 on and off and should consider myself a total beginner. I wrote a lisp routine with wordpad (zz.lsp) to automate a few simplecommands - zoom; explode; wblock. I saved the file to a location on our network and loaded the routine.Acad answers by saying: zz.lsp succesfully loaded. However I have no clue how to start the routine. I thought if you save the routine as zz.lsp you can start the routine by typing zz at the command prompt or you could attach it to a command button. This does not work. Acad tells me this is an unknown command. I'll appreciate any help.
