Your software is powerful, convenient, efficient, the concept and theory of the structure is very clear, and I have learned a lot through using this software. For example, the modeling of the cable is very efficient and convenient.
In SAP2000, either the members are used to simulate the cables and the prestress is added by temperature reduction, or the cables have to be drawn out one by one. In RFEM, in the curved surface panel, you can directly add the supports perpendicular to the curves. This is very efficient. RFEM can also calculate the membrane structure, including the air pillow type of membrane structure; it is really full-featured.
