Change Position of Front Clipping Plane

[kpennell]

Can anyone think of any reason why the following code won't work?  Just testing as of right now.  The current position of the front clipping plane is about -500, and the back clipping plane is about -760.

    (setq VPortEnt (ssget))

    (if VPortEnt
        (progn
        (setq VPortEnt (ssname VPortEnt 0))
        (setq VPortEnt (entget VPortEnt))
        );progn
    );if

    (setq NewClip -600)
    (entmod (subst (cons 43 NewClip)(assoc 43 VPortEnt) VPortEnt))

If I understood correctly,

you're trying to entmod a viewport, and you can't entmod a viewport!

To change the position of a named view clipping plane, you may entmode the named view...
