PLEASE SEE ATTACHMENT: Any Ideas on why my UCS keeps giving me these lines attached to my UCS. It not only attaches here but also on each of my Objects. It slows down the computer and the only way I can seem to get rid of them is by shutting down the program and reopening. Is there a quicker/more efficient way of fixing this issue?
I have the same problem.
The ghost lines appear after working for a short while in all visual styles except 2dwireframe, attached to both 2d objects and solids. Turning off AutoCAD hardware acceleration solves the problem, though I haven't tried adjusting Nividia driver settings.
Windows 7 64-bit, video card is Nvidia Quadro 4000 driver version 126.96.36.19961
The most likely cause of this is a graphics driver problem.
If you are using a certified card then you should use a driver listed here:
If your card is not certified then try switching hardware acceleration off as suggested in the previous post.
I changed the driver and the ghost line problem eventually came back.
It might be an AutoCAD problem, because:
- the lines start at endpoints and go along the world UCS X axis whatever the current UCS
- The ines don't attach to starting points, only ending points of lines, arcs splines, plines etc.
- the lines rotate with objects in a polar array if it's associative, otherwise they do not
- when drawing a polyline of zero width temporary lines appear at pick points, give it a width and they do not
- the lines attach to some points of the XYZ characters in UCS icon
Does this UCS issue occur in all drawings that you work on or just specific ones? I am asking because you can sometimes get unusual display issues if your drawing is at very high coordinates.
When it happens, it is in all drawings at the same time. Close and restart AutoCAD and the drawings are all fine for maybe one or a few hours then it happens again.
It's in all visual styles except 2dwireframe, but shows when orbiting in 2dwireframe. Drawings can be all 2d objects or with solids and surfaces. All lines, arcs and splines show it, and some 3d objects. I'll try to get a screen shot next time.
This happens to me quite often, but only when I've worked with a number of large files and have pushed memory usage to the limits.
Once they appear, the only way to get rid of them is to close and restart AutoCad.
so far we have not been able to reproduce this phenomenon within Autodesk Support.
It would therefore be great if we could get more details on the system configuration of affected machines, like what operating system, what video card and driver, how much RAM the machine has etc.
Also if anyone has exact steps how to reproduce the issue, this would be great.
Once we can reproduce the issue, out development team can look into what may be causing it.
Many thanks in advance!
My machine is an HPZ800, 64-bit, 12.0 GB RAM, INTEL XEON CPU E5506 @2.13GHz (2) processors
OS - Windows 7, Graphic Card - ATI FirePro V8700 (FireGL)
I know it happens when I am 3D modeling, but cannot tell you that there is an exact step that makes this happen. The only way to get rid of this issue is to restart the entire program. Even with exiting the file out and reopening it still appears as my photo shows. Notice: This issue doesn't seem to happend when working in 2D or a very very small 3D drawing.
Please let us know what you come up with. Thank you!
Please see attached pictures. It has happened a couple of times today. Picture 1 shows UCS before shutdown and restart (with error issue), Picture 2 shows the UCS after shutdown and restart (what the object is meant to look like).
Thank you for your help!
