Question
After importing an .stp file, my model is unstable. What can be the reason for this?Answer
There can be many reasons for that. Your model may have tension members and you did not deactivate the "Connect Crossing Members" option during the import.
Figure 01 - stp-Import - Settings
Your model is unstable at the crossing points of tension members.
Figure 02 - Error - Crossing, Connected Tension Members
If I deactivate this option, I still get an error message. Why?
The calculation parameters were probably not adjusted sufficiently in the file before. Tension members often require a special treatment, which can be added in the calculation parameters.
