How to use extrim by pyautocad?

[01131042]

I wanted to use extrim command by this sample of code:

command = "extrim "
doc.SendCommand(command)

Then, user have to pick a polygon by hand. I want to provide there an object predefined in code. Is there an option to pass an object into command instead of picking manually?

@01131042 ,

This area of the forum is for Autolisp/Visual Lisp customization.

Your snippet doesn't look like Autolisp.

If it were Autolisp you could use the vlax-add-cmd function to make an AutoCad command of it without having to modify the code, e.g.

(defun tires ( / #)

  (setq # (getint "\nHow many tires are on the vehicle?:  "))

  (princ (strcat "\nThere are " (itoa #) " tires on the vehicle."))

  (princ)

)

(vlax-add-cmd "tires" 'tires)

which allows you to feed the # from the command line, e.g.

(command "tires" 4)

Have a look inside Extrim.lsp and you will see a defun (Etrim, so if you (load "Extrim") you can call the use of it by (Etrim ent pt), hopefully you understand.

Lisp doesn’t have a SendCommand? (vla-sendcommand)
