Greetings colleagues, I have the following problem when trying to export the Revit 2019 model to IFC, the export window shows the file that will be exported, but it appears dimmed as if it were not inactive and when I execute the export it does not export anything ...! no matter how much I configure or change options, that's why I go to see if someone has had this problem ...! and tell me how I can solve it.
Thank you very much in advance for anyone who can guide me ...!
