viewport frame missing/ viewport frame disapeared

[Lyonstp]

I have a plan and profile sheet set up with two viewports in it. Somehow one of the viewport's frame disapeared and I don't know how to get it back. Since it is not showing I can't click on the viewport to unlock it and adjust the view. I also can't delete it. Can someone please help me with this asap! Thanks!

Usually the frame disappears because I have accidently put it on a layer that I have turned off.

oh DUH! that was it. Thanks!!

LOL. I usually discover when I'm about to kick the computer and my partner in crime reminds me to check.

I was trying to find a solution to my missing viewport boundary and found out that if you used vpclip to redefine the boundary and deleted the polyline, your viewport doesn't show the boundary.  You can maximize the viewport and then minimize it to restore the boundary.

This also seems to happen to me a lot when I do not edit the viewport using vpedit or changing the layer of the boundary. I am unsure why it happens but I can usually restore the boundary using AMVISIBLE > Unhide > all. Again, I am not sure how it gets hidden in the first place, but if you know you haven't edited the boundary it usually works.

Thank you sooooooo much and huuuuuuuge thumbs up! The UNHIDE command is so useful since I've tried all the other solutions, heartbreaking that nothing works. Same as you, I have no idea how things disappeared at first, neither. But again, thanks a lot for this message, which did save my whole day work!

That was a post from 2017 and was the posters only post to the forum. That command comes from AutoCAD Mechanical.
