This post is going out to my homeboy Troy who said something to me today along the lines of, "None of the blogs are giving any good information right now. All anyone can talk about is AU! I probably won't see any decent posts until late December."
Guilty as charged. My challenge to fellow bloggers is: post something that has absolutely nothing to do with AU, before the Thanksgiving holiday.
In the last few days I've run into several people who are having problems with their Civil 3D 2011 graphics acting really annoying after service pack 1 was installed.
Some are seeing the viewcube show up with a white background (even when their modelspace background is black!).
Some are seeing this issue manifest itself as an error with "The configured Heidi driver cannot be loaded. Switching to default software driver."
Some are seeing "Exception in acmapworkspace.arx ARX Command" or "Unhandled exception 28ed90 (access violation reading 0x0028) at address blah blah blah..."
No matter how you are experiencing it, the root cause is the same: your graphics card is stressing out about Civil 3D.
First thing to try:
Make sure your graphics card is up to snuff. Is your card supported (or is it a cheap piece of crap that came with your box-store purchased machine)?
If the card is supported, you may just need to update the driver. Do that here: http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=6711848&linkID=9240698
If it is a cheap p.o.c. look for a new card here: http://www.nvidia.com/object/bfp_autocad_2011.html
Second thing to try (stolen from: http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=15851876&linkID=9240697):
- Inside of your application, type 3DCONFIG at the command line.
- In the dialog box that appears, select the Manual Tune button.
- At the top of the Manual Performance Tuning dialog box, toggle the 'Enable hardware acceleration' option.
- Select OK and OK to return to the drawing workspace.
- Repeat steps 1-4 again to toggle the 'Enable hardware acceleration' option back to its original setting.
