NX10 memory access violation error
NX10 memory access violation error
(OP)
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.

RE: NX10 memory access violation error
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.

RE: NX10 memory access violation error
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.
RE: NX10 memory access violation error
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.
RE: NX10 memory access violation 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.

Tomas
RE: NX10 memory access violation error
I had an older system at home that while the Radeon card worked, it was not a supported card at the time.

RE: NX10 memory access violation error
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.
