Hi,
I've got a Revit 2015 model that keeps crashing, but that also won't let me alter certain elements. I'm just guessing but I think the 2 issues are linked. The element-related error I get is as follows:-
"cannot construct Analytical Geometry"
and this comes after Revit hangs for about half an hour, usually after just trying to something simple like changing a slab to a different thickness. As it suggests an analytical model issue, I've tried disabling the analytical model for all elements, but with no improvement.
If possible, I would like to get someone more experienced in these things than me to have a look at the file, but the file is about 67Mb in size...
We will analyse the file if you post it.
Quick tip: Switch off 'Structural' checbox for error related elements, not only 'Enable Analyticla Model' paramater.
