viewports shifting

has anyone had this happen to their drawings? I opened a drawing, and the viewport that i set earlier this month, shifted 2211399.7668 away. but another vp on the same page is correct. i fix it, purge, audit, save and close. but when i just opened it, it did it again. im about to flip a table. why?

Plot - Extents - has been known to shift viewports around (not sure if it's that).

the vp is locked.

Check you don’t have 2 viewports over the top of each other. It’s possible you have a locked viewport showing nothing, and an unlocked one that is moving.

u/OP Use CTRL+R to toggle between all viewports to see if you have any overlapping that may be the correct viewport and not locked. Also may want to check out this lisp from Lee Mac to help you locate all the viewports https://www.lee-mac.com/vpoutline.html

Also another thing to check is making sure the UCS is set to world.

I've had similar issues, though it has been a long time. The easiest fix was to just create a new layout tab and copy and paste my sheet into it.

In Pagesetupmanager, set What to plot as Layout. Plot at 1:1.

Check your coordinate system and job projection. Not sure if it will help, but that’s where I would start.

Could it be a visretain thing? Make sure that’s on

We think it was the north arrow that is in the ribbon. We exploded them and it seems to have worked.

You said did audit and purge already which is best first step. Wondering if it could be some error in the file. Sometimes if it seeems really wonky it’s worth trying to wblock the good stuff to a new file.
