I've modelled a prefabricated cabin with STAAD.PRO and everything was almost good since something has happened. I ave two different kind of plate. One (floor plate) is 5mm thick and the other one is 2mm thk (corrugated steel plate for roof and walls).
I selected the floor plates and I have assigned the plate 5mm thick (everything ok).
I selected the wall and roof plates and I have assigned the plate 2mm thick. The results is that the roof and the transversal wall have accepted the modification, the longitudinal wall instead no. Have been created 3 new plate type 2mm thick that I'm unable to delete. Somebody can help me?
thank you
Riccardo
