NX10 memory access violation error

[Karlis]

Hi I have stumbled across this error and it appears to be solved right here on eng-tips forums.

The remedy was stated as follows, but the subject is closed..

/Go into your display properties....goto the "advanced" tab which can be found on the "settings" tab. From there under the "troubleshoot" tab turn the hardware acceleration all the way off. Then try to open your part or whatever. If it works with that acceleration turned off it is a problem with your graphics card/driver. Just FYI...I've never had good luck with ATI cards and UG./

I have only one question.
Where are these "display properties"? I have been searching all over but I am unable to find it, thus I'm not sure if it corresponds to NX itself or my graphics card which is ATI Radeon HD 8370M.

This error appeared a day ago and it persists every time I try to update my model (part).
Thanks.

I think this is what you're after and it's in Windows you do it. I got this from Siemens Solution Center a while back:

The technique for turning OFF graphics card hardware acceleration has changed
significantly under Windows 7.

STEP 1) Locate graphics device on host

Start ->
Control Panel ->
System and Security ->
Administrative Tools ->
Computer Management ->
Device Manager ->
Display Adaptors ->

STEP 2) Disable graphics device

<Right Click> on grahics device (ie NVIDIA Quadro 600)

SELECT "Disable"

Informational dialog will be raised

"Disabling this device will cause it to stop
functioning. Do you really want to disable
it"

SELECT "Yes"

STEP 3)

Reboot host.

STEP 4)

Test to determine if problem still exists

YES) if problem still exists, then NOT a graphics device issue.

NO) if problem does not still exist, then a graphics device issue.

Caveats:

Host performance will be impaired with graphics device disabled.

And how is this going to solve my problem exactly?
I know there is a remedy for this, but it seems that no one is willing to explain it step by step. The method you posted simply describes how to disable a graphics card. What I need is an instruction on how to disable the hardware acceleration for this graphics card.

Graphics card = hardware acceleration.
Disabling your graphics card won't necessarily solve the problem, rather it is a step in the troubleshooting process that tells you whether the problem you are experiencing is due to your graphics card/driver or something else. If you disable the graphics card, reboot, restart NX, and still encounter the problem, then the graphics card is not the cause. If the card is the cause, try different driver versions to find one that works; you won't want to use NX without the help of a graphics card.

- How did you come to the conclusion that that other thread contained the solution to your error ?
- just because both your session and what's described in that other thread has the "memory access violation" message ?

Memory Access Violation in NX means "You just encountered an error which there is no detailed error message for". - It's the NX equivalent of the windows error "Unknown error".
All detailed error messages has been prepared in advance, such that the developers have predicted that when the user is doing this and that, the xxx might fail.
Therefore the developer has prepared a message "the xxx has failed, please do yyyy and zzzz".

If you have tried disabling the hardware acceleration, and that did not help.
Read the NX logfile after the crash has occurred, search for "+++" and read the detailed error message .
many times you can get quite a good indication on whats wrong.
Have you tried running Part Cleanup ? Do that and save the part.

Is the ATI Radeon chip/card set supported by NX?
I had an older system at home that while the Radeon card worked, it was not a supported card at the time.

I really doubt that my card is supported, it is a weakling by comparison, but for some reason it worked fine for over a year. And now this. I haven't updated anything.
I assumed the question was solved because it was closed, and because the creator had written "success" in correspondence to what I quoted at the beginning of this thread. As I am not a computer programmer, nor expert, I did not know from birth that hardware acceleration = graphics card.
Thank you for the suggestion Thomas, I will try to run the part cleanup.

Threads at eng-tips get closed automatically if there are no replies within a certain time frame (6 months, I think). There is currently no way to mark an issue as "solved"; if any stars were awarded, then it was probably solved - or at least something useful came of the thread.
