LISP zooming

Hey,

Is there anyway to zoom in and out or to control the viewport

properties via lisp ?

Thanks

Zoom with lisp? Why yes you can. Here is a small example as provided by the Lazy Drafter website.

; Zoomout

; Zooms out by a factor of .5x

;

(defun C:zoomout ()

(command “zoom” “.5x”)

)

What do you mean by "control the viewport"? The layer it is on? The size? Placement? Whether it is locked or unlocked?

Here is another example but this time it is a lisp routine that will lock a viewport.

Make a specific viewport current via lisp.

Set viewport scale with DCL/lisp.

Great ! thanks.

Just a simple one usefull in lisps etc

(command "zoom" "C" pt 100)

zoom about a pick pt for a predefined scale.

Also consider the zoom* methods of the Application Object, e.g. vla-zoomwindow
