Post by: fathihvac on April 17, 2013, 10:28:18 AM

Hello,

  When using autolisp custom commands in the following code :
(command "MyCustomCommand")  it gives "unknown command press "F1" for help" ,to your knowledge the autolisps are already loaded and my custom commands run when i launche them from my custom toolbar.Any help.

Sorry for my poor english.

Call your command with:

Code: [Select]

(c:MyCustomCommand)

Yep, unfortunately acad cannot call one lisp command from another lisp using the command function. And even if you do as Lee's shown, you can't send that command any arguments (e.g. if your custom command asked to select entities).

The only alternative is to split the original command into a normal lisp defun and a c:* defun which calls it using arguments:

Unless the vlax-add-cmd function has been used  ;-)
