I just installed AutoCAD 2015. When I open up my existing drawings all these crazy lines appear. I have attached a .bmp screen shot. When I print the drawings these lines do not appear anymore. They seem to jump around when I zoom in and out of the drawing. Does anyone know what they are and how I can get rid of them?
Thanks!

Hi,
have not seen then yet (except an old issue with hatches).
Can you upload that drawing? At least with a cleaned modelspace so you don't publicate the model, but only if the lines are then visible too! 😉
Have you tried to run command _AUDIT and see if there are defects in the drawing database?
Can you try to run command _WBLOCK with option "entire drawing" and see if the problem also appears in the resulting dwg?

Hi,
well, on my system there are no strange lines.
So what are your system infos (operating system, graphic card + driver release)
Can you try to disable the hardware acceleration and see if it happens again?

Alfred you nailed it!
I turned off the hardware acceleration and everything looks fine.
Thanks
Hi,
and now it's up to you (or your admins) to find a driver and/or a graphic card, that is working also with AutoCAD 😉
Good luck, - alfred -
I am also having this same problem. Super frustrating. How exactly do I change the accelator specs on the computer?
thanks

>> How exactly do I change the accelator specs on the computer?
Command _GRAPHICSCONFIG is one option, the other is a icon within the statusbar-switches (lower right border of the AutoCAD application window).

Hello
To solve the strange graphic problems of the 2015 version, you can/try :
- Install the latest graphic card driver
and/or
- Disable the Hardware Graphic Acceleration
and/or
- LINESMOOTHING = 0 (Idem Smooth Line Display Option)
and/or (if you have an NVidia graphic card)
- Disable the NVidia FXAA Anti-Aliasing feature

Did update to latest and greatest AMD drivers. Did not solve the problem.
Turned off hardware acceleration and that did solve the problem.
Turned HW acceleration back on and just disabled line smoothing (via the check box under HW acceleration, same as LINESMOOTHING <OFF>).
I was just posting to point out that the complete disabling of HW acceleration is not required. Only disabling Line Smoothing.
Thanks for your response.
Disabling LINESMOOTHING isn't necessary either. Leave LINESMOOTHING ON and just set LINEFADING to OFF. That worked for me with my AMD card, at least.
Hmm. Turning off linefading didn't do the trick for me, but living without linesmoothing is a perfectly workable solution for me until this get's permanently resolved by Autodesk or the graphic card drivers.
