It would be a great help if there is a way to show or hide a object only in the current viewport without affecting its visibility in model space or other viewports.
I came across a .vlx file from www.cadstudio.cz/dl./hideshow.vlx that does the job of showing or hiding in model space( and hence in all viewports).
 
If someone got a lisp routine for object display just affecting the current viewport, it'll be real help.
 
Thanks,

Put the object on its own layer and use the viewport freeze option available in the Layer Properties Manager.

You can also accomplish this with commands: LayFrz and VPLayer.

Thanks for the replies. By doing VP freeze or LAYFRZ I would be applying to the entire layer(which turns off all the objects in that layer). I just want a specified object in a layer to be turned off in a specified viewport(not affecting its visibility in model space or any other viewport).
Please find below couple of LISP files I came across few websites that posted LISP files which can turn on/off a object (not layer) in model space. If some pros at autolisp could look at it and modify it to the way I need it will save my day(s).  Thanks in advance,
Suribalu

There is a lisp routine I've seen that will make individual objects "invisible".  Would that be what you are looking for?

Thanks mate for the reply. If the lisp routine you mentioned can make objects invisible just from a specific viewport while leaving the visibility in model space then that's what I'd be looking for.

Nope.  You would be better off putting the object on its own layer and using viewport freeze.
