Lisp command not recognised

[jnj1502]

Long ago I adapted a bit of Lisp code from George Omura's Keycad.lsp routine that combines several keyboard shortcuts into a single shortcut. It has worked well for me, except that one of the shorcuts has stopped working.

The command is designed to set the fillet command to have a 0" radius when the shortcut "ff" is entered. The line in question is as follows:

(DEFUN C:FF () (COMMAND "FILLET" "RADIUS" "0"))

When I try to use the shortcut, the following message appears in the command line:

Command: ff
FILLET Unknown command "FILLET". Press F1 for help.
Command: RADIUS Unknown command "RADIUS". Press F1 for help.
Command: 0 Unknown command "0". Press F1 for help.
Command: nil

If I enter "FILLET" or "F" in the command line, the Fillet command is recognised and works normally.

Any clues?

Oh, in case it matters, I'm running ADT 2005.

Yes it matters cos' FILLET has changed in 2005. The best I can come up with here and now is to set radius separately and then start the command:

(DEFUN C:FF ()
(and (setvar "FILLETRAD" 0.0) (princ "Radius = 0.0"))
(COMMAND "FILLET")
(princ)
)

ADT undefines several commands and substitutes its own in order make it possible to use apparently AutoCAD commands to modify ADT elements. This can adversly affect customizations. Use (command "_.Fillet") to get access to the AutoCAD command or use (command "_AECfillet") if you want it to work on ADT elements. In general it is good to use a "_." prefix for commands so that
they are unaffected by command redefinition.

Excellent point, dbroad

Thanks to you both. My shortcut is working again.

What other commands require the "_." prefix in order to be used in LISP routines within ADT?

[robert.1.hall72202]

thats all you use???
mine looks like this


;Zero Fillet
;-----------
(defun c:FZ ()
(setq Save_FilletRad (getvar "FILLETRAD"))
(setq Save_TrimMode (getvar "TRIMMODE"))
(setvar "FILLETRAD" 0)
(setvar "TRIMMODE" 1)
(setvar "CMDECHO" 1)
(command "._FILLET")
(while (> (getvar "CMDACTIVE") 0)
(command pause)
)
(setvar "FILLETRAD" Save_FilletRad)
(setvar "TRIMMODE" Save_TrimMode)
(princ)
)



Maybe I have more here than I need?

In general, its safe to add "_." to all command calls. Always test.
You may use the "_" prefix for subcommands but don't use "_."
The underscore is a translation prefix, enabling the same code to
be used for international versions of ACAD/ADT/....

I don't bother saving filletrad because I usually want to keep filleting at 0 after FZ.
