New command button to open a template

does anyone know how i can open an existin drawing from a button or pull down? I need the script

Well you can get a menu that will open a drawing by pressing

"Ctrl-O" if you have it set as default value for it.

"Ctrl-N" gives you a new drawing

Maybe this will help you:

i too am looking to do this..... the above link is helpful but the solution is a lisp code. rkmcswain says

Try this:

(vlax-invoke-method
   (vla-open
    (vla-get-Documents
      (vlax-get-acad-object)
    )
    "C:\\BBBB.DWG"
  )
 "Activate"
) 

is it possible to put this in a macro, or attach this code to a button?

thanks all

or how would i add a definition to the beginning of this so i can run it from a command?

i've not seen a lsp like this before that runs automatically - i would expect to load it first, then use a command to run it?
