Manipulate viewport with lisp

Is there a "command" or other method I can use to change the properties of a
viewport using lisp? All of the variables are read-only, and none of the
commands seems to allow me to change the properties I want. I want to be
able to change the viewport height and center for both paperspace and
modelspace.

Any suggestions?

Thanks,
Chad

 

Chad,
Viewports can be manipulated with visual lisp (AutoLISP using the active-x
extensions) but not with plain autolisp and/or the lisp command function.
For an example of using vlisp to change the layer of a viewport, search the
newsgroup for a thread titled: "Changing Viewports to Diff layer, Entmod not
working?" (thread started 27 June). One of the posts in this thread
includes a routine to change a viewport layer. While it doesn't
specifically solve your problem, it would't be too difficult to modify it to
change the viewport height and centerpoint in paperspace. Changing the view
settings in model space may be a bit more complicated, that's something I
haven't done.

HTH,
