I have a model that is causing access violoations in FreeCAD during the graphical display of the model.
The model is very large - 1.4 mb, and contains ARCH/DRAFT objects.
If I turn off the display of all arch objects, save one, I can open the model and pan, zoom, rotate to my hearts content.
However, as I enable the display of more objects, the display freezes on me and an exception is thrown/caught.
My system information is
OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.16110 (Git)
Build type: Release
Branch: (HEAD detached at upstream/releases/FreeCAD-0-18)
Hash: f7dccfaa909e5b9da26bf50c4a22ccca9bb10c40
Python version: 3.6.6
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)
I also run a Radeon RX 7 570. The radeon software version is 19.4.1.
I have attached the screen shot showing the error
What other information do you need? Also, how do I provide the model given that it is too large.
Finally, what command line arguments can I give to FreeCAD so that it will give us more information so we can debug this problem?
Regards,
David

Re: Need help diagnosing access violation
I forgot to mention that the same model works fine on an old Lenovo Thinkpad 410 running Windows 7.
It also works fine if I boot my workstation with Ubuntu 18.04.2 instead of Windows 7.

Please read item 5 of the forum rules above, it mentions alternatives.
See Start up and Configuration
Then this may possibly be a graphics driver issue... In recent months we've seen people having issues on Windows after updating their Radeon driver (sometimes the update was automatic). Some reported fixing their issue by downgrading their graphics driver...
