problem with ifc export

[NOPKGer]

does anyone else have problems with ifc export via the API?
When I try to export larger files (> ~4000 elements) Cadwork crashes. And I get the following errors:
QtWarning: QMutex: destroying locked mutex
QtFatal: QThread: Destroyed while thread is still running

it seems to happen especially if the file does not exist before.
In addition, all active elements are always exported even if I enter an empty list in the function

here is my code as an example:

def export(activeElements):
    userpath = uc.get_user_path_from_dialog()
    filename = uc.get_3d_file_name().split(".3d")[0]
    filename += ".ifc"
    filepath = os.path.join(userpath,filename)
    bc.export_ifc(activeElements,filepath)

Hi @NOPKGer ,

The export is running in another thread. If you run this and continue to use the 3d in parallel and change elements, for example, this can lead to problems.

Do you change the model while the export is running?

In the next update, this export (bc.export_ifc(..)) will be executed with Progressbar.

If you want to run the export silently, please use the following functions (Here too, UI interactions such as visibility control and changes to elements can be problematic):

bc.export_ifc4_silently(...)
bc.export_ifc4_silently_with_options(...)

Hey, I didn't do anything during the export.

but with the silently function it seems to work at least that not all active elements are taken for export but it still crashes.

could you pls attach your 3d file (it has to be zipped for uploading) ?

I was able to reproduce the problem. However, this only happened if I show or hide elements while the export is running.
We will discuss this internally and work out a solution.
