AutoCAD Civil 3D

[#1]

When I start C3D 2011, it starts to load and then freezes once it gets to loading AEC Point Cloud and the acad.dwt.  It started to do this once I set Hardware Accelerator to be on. It will load about 40% and then totally hose my entire computer.  And of course now it won't load so I can't shut the setting off. Anyone seen this?

TIA

Hi,

I don't understand how AutoCAD is on the way to start, the acad.dwt is not loaded but access to a point-cloud is active/is to be loaded.

May be this is not interesting at the moment. Open Windows-TaskManager, look if there is a process called like WsCommCntrl*, if so and if that is using processor power ==> kill it, and then look back to AutoCAD how it works now.

The problem is....when the program freezes it completely freezes my computer.  Task manager will not open, crosshairs are frozen.  I actually have to turn the computer off with the start button.

Hi,

>> [...] it completely freezes my computer

extremly unusual that the computer freezes at all, or it's some hardware or hardware-driver issue.

So what sysinfos do you have (processor, graphiccard + gc-memory, main memory, operating system).

Did Civil3D run already and the problems came up later or have you just installed it?

What happens if you login with another user-account to your Windows and try Civil3D again?

1] restart the machine in Safe Mode

2] log in as admin

3] first, run Task Manager, and set its visibility as "Always on top"

4] after, run Autocad

Now you should be able to switch off every undesidered setting, and eventually kill the acad.exe process.

You can turn off the Hardware Acceleration at startup by editing the Target in the shortcut used to start C3D. It should look like this in the Properties for the shortcut:

"C:\Program Files\Autodesk\AutoCAD Civil 3D 2012\acad.exe" /ld "C:\Program Files\Autodesk\AutoCAD Civil 3D 2012\AecBase.dbx" /p "<<C3D_Imperial>>"

At the end of this, add a space then /nohardware 

This will disable HA for the session, but will not alter the setting in th eregistry. So be sure to turn it off in the settings. Once the settings are setyou can remove the /nohardware switch.
