Whilst rendering a view in AutoCAD 2012, depending on the resolution I set it at, a fatal error occurs and AutoCAD closes or the render disappears in place of a small square in the bottom left hand corner and it claims to be finished. Currently, I am restricted to setting the resolution to 1500x1200 without it crashing but would like to ideally use a much higher resolution. To add to this the more detail I put into the drawing, the lower the resolution must be to avoid a crash - is there a way to avoid this?

I have seen suggestions, when trying to render for a large format poster, to render in segments and stitch together on alternative software. Is this actually possible on a perspective view as each time you move the camera, the perspective changes?

Could it have anything to do with your system specifications?

I hope not, it's more or less new.

You may well need that Nvidia something plus card.  No kidding.  Think about it.  What is rendering?ShadingTexture mappingBump mappingFoggingShadowsReflectionsTransparencyTranslucencyRefractionDiffractionBlurIlluminationNeed more to understand how this is all about the power of your graphics card and not CPU cores and onboard RAM?  Your system is screaming for help and curling itself up in a fetal box in the corner of your display.Dave.

I've kept it pretty simple in terms of rendering at the moment, just set it to presentation (5) turned on sun status, full shadows and sky and background illumination.

Here are the full stats for my comp:

700W PSU     
AMD FX 8150 (8 x 3.6 GHz) AM3 16MB - Black Edition     
NVIDIA GeForce GTS 450 - 2 GB - (PALIT) - (PCI-E)     
16 GB 1333 MHZ (4x4GB) - (DDR3)     
Asus M5A78L-M/USB3 (AMD 760G) - VGA     

I think the main problem is that i've gone into too much detail and the file size is gigantic (over 100mb).

Rendering is heavily dependent on the CPU and RAM and not on the graphics card.

A 100 MB file is going to be taxing regardless.  If you can't get that down then breaking the file into smaller pieces for rendering may be an option.
 
Another option might be to render it in the Autodesk cloud.  It's worth a check.  Every Autodesk licensed user has access, subscription users have more storage.  It may depend on your company policies as well whether this is an option for you.

Thank you for your responses. I have "WBlocked" as much of it as I can which has drastically reduced the file size - approx a third.

As a result, I have not yet had any problems with rendering albeit only at 2000x1500 - hopefully when the model nears absolute completion I will try for a much higher render output and if need be the use autodesk cloud.
