fatal error: unhandled access violation reading 0x0000 exception at 328162a0h

[Anonymous]

I am user of AutoCAD 2012 and a beginner in 3d. I made this 3d box culvert drawing in Acad2012 and tried to render it, but the program abort and gives the message: fatal error: unhandled access violation reading 0x0000 exception at 328162a0h. I did search in the web and a possible solution was that the reason is that the medium library has to be downloaded because not everybody uses it, and for that reason it's not installed with the program. I tried this solution, went to autodesk and downloaded it and installed it. Apparently it is installed ok, but when I open the drawing and try to open the render library the same message appears and abort program. 😞  And attachment is available for checking. Thanks in advance to whom may help.

sisonricosison, thanks for your response. The program opens and run just fine, the abort problem occurs when opening the render option window.

Hi,

>> tried to render it, but the program abort and gives the message

You should take care about some points:

• When you do _ZOOM _EXTENTS you'll recognize that there are objects far far away from each other. Especially for rendering it's extremely important that the scene is correct.
• When you render, you should always do that in perspective mode, that is the only valid definition for the distance between the objects and the camera. When you are working in parallel mode the camera might be close to the object or far away (or even behind the objects).
• Avoid high coordinates ... from the objects mentioned about (distributed far away) there are e.g. 2 block-insertions at a coordinate of X=-499348.7416 / Y=-2.4020 / Z=505222.1143 .. X and Z value are at a range where every render algorithm has it's troubles.
• When I opened your drawing (with AutoCAD 2017) I ran command _AUDIT, it found 2 errors. Not sure if your AutoCAD 2012 find them too, but it's worth to try that.
• Whenever a drawing crashes a good way to try is to create a new drawing parallel to the current one and then use copy & paste to get the geometry into the new drawing ... does _RENDER again crash?

Good luck, - alfred -

Alfred.NESWADBA;

Thanks, very much. I did exactly what you recommend and it worked. Yes, AutoCAD 2012 through audit found the 2 errors and fix it too. I did the other steps too. A drawing is attached. Thanks to God and thanks for your detailed instructions. God bless you.
