Autodesk does not warrant, either expressly or implied, the accuracy, reliability or completeness of the information translated by the machine translation service and will not be liable for damages or losses caused by the trust placed in the translation service.

Does that also happen when you use AutoCAD PDF (General Documentation) yes.

Please mark a post or posts as accepted solutions if they resolved the issue or give me a bit more detail on this issue so we can continue to work towards getting this solved.

If it does, then the culprit is likely your graphics card driver.

I am using Dell Inspiron 5402, Intel i5 11th gen, Intel IrisXe processor.

It is important, grab it from your Autodesk Account Updates page here Your video card is troublesome based on feedback by others that I noticed in these forums recently: in GRAPHICSCONFIG command turn off hardware acceleration nd see if your issue goes away.

Also tried, turning off the hardware acceleration, but no changes.

I have been using mechanical desktop and have been successfully opened and edited other.dwg files.

So only this particular file cannot be opened.

When this file was opened, the error pops up and forces you to click OK.

However, this particular.dwg file can be opened successfully in Draftsight, which tells me the file is fine.

Does anyone have experience solving this issue Please help me with decoding this issue.

Error means little, its a generic crash report: open your file with RECOVER or RECOVERALL commands in AutoCAD and fix it if you dont want to open it in Draftsight (which is less picky about file formats) and save in Draftsight first.

We have some known issues with drawings created or modified with Draft sight.

Then reopen again in Mechanical Desktop will solve the issues.
