Ответ:
Если вы используете стержни с сечениями, которые неизвестны в интерфейсе, вы должны применить файл преобразования для сечений. This mapping file can be easily filled with the names of the cross-sections. In the left column of the table, write the names of the cross-sections used in TEKLA, and in the right column, write the DLUBAL names or select them from the library.
Please watch the attached video.
Внимание!
In TEKLA, you have to have the right environment. In the video, Chinese cross-sections should be transferred, so the Chinese environment has to be used in TEKLA.
