Can you confirm which templates you are using ? Does it make a difference if you use the as-shipped templates ?
Your comments about what happens after selecting the sketch plane could indicate a potential graphics issue - have you confirmed your graphics drivers are current ?
When you state this started to occur after installing some MS updates - can you confirm which MS updates ? You can see which were installed & when from Control Panel, Uninstall Program, View Installed Updates.
If you have installed .net4.5 then that could be an influencing factor - 2013 currently supports .net4.0 not 4.5
PS. Support for backward compatibility is absolutely nothing to do with forcing you to do upgrades, (yes I could have used a different phrase there).
1. I am using the as-shipped templates.
2. Because of your suggestion I took the time (and risk) to upgrade my Nvidia drivers but the problem still persists
3. I will try to attach a pdf file of the latest MS updates that correspond to the time frame of failure of Inventor.
4. I have NOT installed net4.5. In trying to determine if was done automatically for me I looked at the upgrade record under the control panel util "Uninstall an update" and all I see is .NET Framework 4 client profile and .NET Framework 4 Extended.
Well we're not aware of any issues related to what you show there.
As a next step could you try unloading all add-ins from Tools, Add-ins & retrying.
Also, try using the App Options, Hardware tab to try the various other grpahics modes. Note that you'lll need to exit Inventor after making these changes to ensure you're using the new mode. Does Diagnostics from the App Option Hardware tab show any errors ? (Right at the end of the report).
Sorry for the delay but had to get parts out the door.
I never found a fix for this arbitrary problem triggered by a Microsoft automatic update.
Finally removed IV 2013 and reinstalled plus SP1. Also reverted back to my "good" GPU driver.
As I type this I am back on line. I will let you know the next time this happens.
Thanks for your effort on this issue.
I'm having similar problem of what this person posted. Can you sent me active link where I can download update of: DL20082900 in 64bit please. there was broken link!
