Unknown Error in the analysis of tendon module

The same file worked for me once but now I am facing following issue.

The tendons are exported to .dat file from the database.
Let me know how I can identify the issue.

Thanks!

Hi stak,

thanks for sharing. The error can be related to many things in the code, therefore I don’t know what the actual cause is. Can you provide us with the project files (*.sofistik + *.dwg OR *.dat file) in order to recreate and fix the issue?

Thanks
