We've had a few users noticing problems with entities becoming invisible in Map 2013. This has happened in a couple of different ways: 1) copy and pasting a block with editable attributes from one drawing into another can make objects disappear; 2) using Dview -> Twist to change the drawing rotation usually causes objects to disappear. The entities are still in the drawing database and can be selected, but they aren't visible and can't be picked by the mouse etc.
If I save and reopen the drawing, or wblock everything out to a new drawing and open it, then they all show up as they should, but that is a bit of a pain. So has anyone else experienced this or have any idea what might be going on.
BTW, this is happening on some older Windows XP machines as well as some newer Win7 systems.
>> copy and pasting a block with editable attributes from one drawing into another can make objects disappear
I know 2 options where that should/could not work (has phenomens like you described):
>> using Dview -> Twist to change the drawing rotation usually causes objects to disappear
What objects do disappear (select them and let us know what the property window or the LIST-command gives you as info about the object type). At least it might also be annotative elements and with _DVIEW in a viewport you have set the viewport scale to another scale then before _DVIEW.
Anyway the above suggestions are only valid for some very special cases. It might be helpful if you have a situation that you can reproduce, one drawing with elements to copy from and another drawing where the issue with disappearing happens when you paste geometry (or the drawing when objects disappear after command _DVIEW) ==> upload these drawings.
As long as you get these errors you should run _AUDIT quite often (or open the drawings with command _RECOVER instead of _OPEN). It might be a defect drawing and anytime you insert that special drawing into the current one you duplicate the defect (it's like a virus then). So if you get errors in your drawing remember back to what you did a few commands before to isolate the problem.

The behaviour I've mentioned has shown up on a few machines since moving to Map 2013, but so far it has been intermittent and I've had difficulty reproducing it today.
In answer to your reply Alfred, this has happened in situations where a block was already defined in the target drawing AND has also happened in cases where the block was not predefined in the target drawing. We don't use dynamic or annotative blocks, these are just the standard, old fashioned attributed blocks.
And it isn't just the block that disappears either, in both scenarios all objects in the drawing disappear. This includes all blocks, hatches, lines, polylines etc for the entire drawing database. I can select anything I want using filters or Quick Select, but I can't see them and I can't select them by mouse. Again, our drawings are quite basic, so annotation scales are irrelevant.
I would suspect a hardware or graphics driver problem, except that, as I mentioned, we've seen it on different machines, with different specs and different OS's.
>> using Dview -> Twist to change the drawing rotation usually causes objects to disappear.
Ok, next shot.
In case of using objects based on the AEC-functionality, like Civil3D has, like ACA or MEP has there is functionality included that might let objects be invisible in 3D-views and visible in 2D/plan-view. So my question is: was the drawing, from where you copy objects from, created/modified by one of these verticals?
And if you have the problem with copy/pastse next time ==> try to wblock this entities into a new drawing, then open this drawing and see if the entities now also disappear when using _DVIEW.
If yes ==> upload this new drawing (and try _AUDIT to see if AutoCAD finds any errors)
If no ==> copy now from this new drawing the entities in your destination drawing.
Good luck, - alfred -
This has been a bit frustrating, but I think I've finally managed to reliably reproduce the error, at least in the case of the attributed blocks.
If I have a standard attributed block and single click on an attribute to activate its grip, then grab the attribute by the grip in order to move it, use the mouse wheel to zoom out and then back in to a different location in the drawing and drop the attribute there, the block I am editing will disappear. If I then do a regen or zoom extents, the rest of the drawing also disappears.
Still working on a reliable way to reproduce this using the dview twist command.
Well i Confirm I have similar problems.
In a viewport in paperspace, if I have zoom in out with my mouse. Map objects appear. If I set my annontation scale from my standard list. My Objects dissappear!!
>> if I have zoom in out with my mouse. Map objects appear.
In case they disappeared: have you tried to just switch off and back on the GIS-layer in the Map3D-workspace?

I'm not sure if your issue is exactly the same as mine or not, but in my case the resolution appears to have been turning on hardware acceleration. I had a parallel thread going on the Autocad group and had mentioned over there that this was resolved - sorry for not following up here as well.
