Hi @jeff
I managed to wrongly call a definition into another definition (instead of the result of the first definition) and this resulted in a total nVidia driver crash, but only on the second run.
The strange thing was that it works OK the first time, but on the second run it crashes. I put the script in a button and ran it from there (it extrudes a mesh and assigns the result an IFC tag)
This is all due to my typing mistake, but I thought it might be of interest to you so do you want to have a look, or is typical for bad programming and thus of no interest?
Cheers
