It seems this disappearing objects phenomenon has not been addressed fully.
My polylines are disappering on me, creating panic as it represents weeks of work.
For full info -
they came in as survey figures, which I exploded down to reg'lar polylines,
as it is easier and the whole drawing gets reverted to simple autocad for the client anyway.
As I work on different layers to see gaps or whatnot, they disappear on me.
The first time I thought maybe I made a mistake and went into an older version drawing,
copied and pasted them in to my current drawing.
Irritating as I was working on a fast approaching deadline.
Then it happened again, and I knew it wasn't me. No regen or audit brought them back.
I find out that I have to close my drawing and open and they will return.
Pretty bad, considering 2013 takes 10 minutes to close and open up to operational,
and yes my computer is beefy enough to handle 2013.
And now I have duplicate polylines in my drawing that I have to find and erase those.
Is there something I don't know about that will prevent this from happening?
or am I doomed to shut down my program every half hour to see what I am working on?
That does not work. This is a very large drawing with weeks of data, data coming in every day.
That does not make sense either, why provide all the survey database and extensive program features
if all we would do is reduce it to a cartoon version to work in?
It should be a working product as is.
Why would an autocad C3D 2013 drawing have an issue with polylines?
I need to be able to manipulate OUR drawing and OUR survey database for our purposes.
I only reduce the drawing when I have to provide data to the client.
I suppose I should clarify.
For my purposes I only explode selected survey features into polylines, utility locates
as they hold no surface value and require a lot of manipulation.
So, polylines disappear. Survey features aren't disappearing.
This is a longshot guess/ experiment: after expolding the figure wbock out (selecting delete from drawing), audit purge. reinsert. Option: open wblocked file FLATTEN, audit purge first.
