Hi
 
i have a ghose line the following drawing which i can not see in anywhere in the drawing, even in the plot preview. but it can be plotted out.
 
also, I can select by using layers (in "s-text " layer)
 
anyone knows how it happened and why?

That is odd, I also don't see it on preview but is on plot. Don't know how it happened, maybe from converting from another application?
 
 
You can select that line on "S-TEXT" and delete it (using QSelect)

Question: Where is this "line"you're seeing?The reason I ask is since you didn't include the XREFs, zhb7, the XREF DWG location is showing up at (0,0) and it is very very small (looks to be about 5mm tall on my screen).Being that the text is showing up at (0,0), when you're zoomed out to the extents of the dwg, it is hidden behind the UCS Icon. If you zoom in enough (to 0,0), you will eventually be able to read the text.Could that be what you are referring to?

Hi Rob
 
This line is in the paper space and s-text layer.
 
and I can find it , del it.
 
just want to find out why and how ?
 
in my option, nothing to do with my xref because without xref, you still can
find it and plot it , just can not see it in any view.

I see it now. I've been playing with it for a while to see if I could figure it out and I'm stumped. I've changed the plot area and location and it always seems to start at the bottom-left corner of the selected window (plot area).You can turn it off by selecting "Hide Paperspace Objects" in your plot window or Page Setup Manager (note this didn't seem to affect the other paperspace objects)

Hi,
 
Actually, that line is a 3d point. but you just can not see in paper space
you can chspace to model space. or you can list it to see the information.
 
but my point is how it happened and how can you find it if it happens next time.

There is just something screwy with that line. "list" says it has coordinates for its endpoints, but says it has zero length.
Using lisp to query the entity data gives weird dat for its endpoint (group 11), as follows:
((-1 . <Entity name: 7ffff70f500>) (0 . "LINE") (330 . <Entity name: 7ffff70b020>) (5 . "30AF0") (100 . "AcDbEntity") (67 . 1) (410 . "BUILDING SECTIONS") (8 . "S-TEXT") (100 . "AcDbLine") (10 377.44 247.445 0.0) (11 -1.#IND -1.#IND -1.#IND) (210 0.0 0.0 1.0))
 
So again my guess is the line was not created initially in AutoCAD, but was a problem in conversion.
 

this 3d point was drawn in Autocad 2011 ( I drew it , at that time , i did not realize it was drawn until I plotted the drawing out)
 
yes, i am also wondering how could 3d length be 0. and not be able to see anything, based on the list information, at least , i should be able to see a point . right?

[QUOTE=zhb7]yes, i am also wondering how could 3d length be 0.[/QUOTE]Length is applied in the X or Y direction (or combination of X and Y), it does not apply to the Z-coordinate. And because it is a point, it will be length 0.HAWDesigner2011-01-04 04:14:27

..to belabor the "point"...
 
Not sure why zhb7 refers to the item as a "point" as AutoCAd considers it a "line". When "listing" it, AutoCAD reports one endpoint (x,y) at 0,0 other at 2xx, 4xx, but says 0 length.  Maybe it is a hybrid line-point :)
 
 

I was kinda wondering that too. :)
