AutoCAD Civil 3D

[#1]

In dialog boxes the drop down menus appear blank until I drag the mouse over it then the contents appear as I drag the mouse across. Also the cursor doesn't echo back (flash). I have tried updating drivers to no avail.

Running Civil 3D 2011 with all updates.

Windows 7 64 bit

16 gig ram

Quadra fx 1800

Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz

I have attached a couple images to illustrate.

My first guess is that your graphic card may need an upgrade.Try following before that:

1. Check if you get the same behavior on other drawings

2. Type 3DCONFIG and go to Manula Tune, toggle "Enable Hardware Acceleration", Apply

3. If you et the same issue on both occasions then I would see if upgrading video driver helps. Just an idea.

Good luck.

Thanks for the input. Your suggestions had already been looked at. Problem persists.

Can you post your drawing? I can try to open it on my machine to see if it's drawing specific.

[#5]

Due to confidentialy reasons I cannot post the drawing. However I can confirm this is not Drawing related.

Which driver version do you have installed?  Check this list for a list of supported driver versions for the Quadro FX1800 with C3D 2011 on Win7 x64.

Can you confirm that you have Update 1 for Civil 3D 2011 installed?

Quadro fx 1800

driver 266.45

C3D has all updates.

You can try turning off hardware acceleration from within C3D/AutoCAD using the 3DCONFIG command -  restart C3D to make sure the settings are in effect.  Check whether your problem is resolved.

From the snapshots you posted, you have a "desktop manager" software that might be affecting display of windows?  If so, you might try disabling that temprorarily to see if that helps.

If not resolved, you may want to downgrade your graphics driver to one that is in the supported list - the one that you have installed isn't listed as supported/certified as of today.

Tried reverting to this approved driver: 8.17.0012.6570. Did not change anything. Also tried running without hardware acceleration,. no change.

Great!  That rules out a lot of what C3D/AutoCAD depends on for proper display.  Let us know the results after you disable the display manager software that seems to be installed on your system (referring to the extra button with <-> on the windows in your snapshots).
