Disappearing viewports

[ragnheidur.karadottir]

Hi!

I have a drawing with about 10 layouts. In some of the layouts some of the viewport have disappeard. When I hoover over the layout tab I can see the viewport, but when I open the tab it doesn't show. I have turned on and unfrosen all the layers, unfrosen all viewports.Any solutions?

 ps.  I made a screencast but I dont know where it is in the world 🙂

check that MAXACTVP is set to big number.
Max active view ports

Hi

I have done that but it didnt help. I have been working on thet drawing and plotted pdf before. But then the viewport was gone in many of the layouts.

[Dexterel]

can you upload a dwg to see if my experience is same? Will also help to understand way this is happening.
maybe audit but probably recover will help here.

OK

My opinion is the viewports have been deleted.
Mechanics how? Who knows? Maybe you select the viewport polyline true a process (quick select or use a layer to make selection true lisps) and deleted.
This is base on my knowledge, maybe someone else knows better and can solve your problem.

I, too, did not see any viewports in the Paper Space tabs. (only at the bottom of the sheet.)

The xref's &/or images wouldn't load for me, which made me think if those images were placed in paper space of each layout tab versus creating a viewport in paper space to show the images from model space.

-Just a thought.

But you are right. When hovering over the tabs at the bottom, the images appear.

[Dexterel]

is it just possible the images were in paper space (and not model) so no layout.
Somebody detach the xref and maybe after reattached in model?
The hovering is the strangest thing, this is my best explanation.

The image seen hovering over a tab is not "live". It's a stored raster as is the preview seen in various methods of opening a drawing file. So the image may show things that are no longer there.

[Dexterel]

Of course, but how do you delete a viewport without opening the layout? This is the strange thing here, the mechanics on how to delete this viewport (if there ever was one).

[Dexterel]

I do not understand how AllenJessup solve this.
By "no longer there" you mean like I said deleted :D?

[AllenJessup]

The only way I know of at present is to use the LAYDEL command and delete the layer the viewports are on. That will delete viewports in multiple layouts. There may be a couple of other ways I don't know of.

[AllenJessup]

I tell the people I work with that unless I install software that records every keystroke and mouse click there is often no way to tell exactly how something happened. If it's not a recurring problem I want to fix it and move on. If something happens once in one drawing it's because of an error. Either on the users part of the programmers part. If it's unusual enough that I've never seen it happen before and if it doesn't happen again it's not something you're going to solve.

Deleted, no longer XRefered, broken DRef, missing FDO. It was there and now it's not.

[Dexterel]

so you agree I was right (and solve this) when I sad:
"My opinion is the viewports have been deleted"
and as I explained to delete the viewport you need a lisp
and other explanation is detached xref.
But yes you are right you solve this, good job.
