==== Export possibilities ====

By clicking on the button {{en:clt:hotspot:software:cltdesigner:manual:modul_stiffness_matrix:export_button.png|}} a csv file will be created, which contains the input data for RFEM 5.

This file is then opened with Microsoft Excel or import by using the "data from text" option.
