ZOOMIN and ZOOMOUT
Can anyone tell me how I adjust the scale parameters for the above command?
When I type ZOOMIN, I get an Input Scale of 2
When I type ZOOMOUT, the Input Scale changes to 0.25
I understand that I can change the scale once I've typed in the command but what if I want an automatic value when I enter the command?

Is there an over ride command which lets me change them to any value I want?

Hi Jeff,
I don't know if is possible to adjust the scale parameters, but a simple way to do it is redefine the commands (ZOOMIN & ZOOMOUT)

Look at the follow LISP sample code...

(defun C:ZOOMIN ( )
  (progn
	(setvar "CMDECHO" 0)
	(command "_zoom 2x")
	(setvar "CMDECHO" 1)
  )
)

(defun C:ZOOMOUT ( )
  (progn
	(setvar "CMDECHO" 0)
	(command "_zoom 0.25x")
	(setvar "CMDECHO" 1)
  )
)

Hi DS,
That looks great - except I don't know how to programme in LISP!
I think a quick self-learning session is in order. Many thanks for your input. Cheers!

Hi Jeff,
glad to help you
