Thank you very much for the report and I am very sorry about the experience!
With your report, we found out that there seems to be a bug in the latest BIMx Desktop application. To help with the investigation, could you send a Feedback through the BIMx app? The technical detail in the Feedback will be very helpful for us to fix it in a future update.
Thank you very much for your help, and we are looking forward to hearing from you!
It turned out that 3DConnexion did not issue a driver compatible with Big Sur yet. As of today, they have just released a beta driver supporting Big Sur. Could you give it a try here and please let us know if it works?
Looking forward to hearing from you!
Thank you for the answer, that is very sad to hear!
For further investigation, the Feedback sending from the app would be the most useful for us. As we notice that we haven't received your feedback sent inside the app yet, I'm wondering if you could help us to send one with the issue description? That would greatly help us to understand the situation.
Please let me know if you encounter any problems with this function. Thank you very much and we are looking forward to hearing from you!
