Hello, there is the "KUTU_KESIT_SON_rv3_mrd" file that I use for ideçelik attached. In this file, when I "copy" the L elements I use for the steps from the file and "paste" the L elements into the same file named "KUTU_KESIT_SON_rv3", HEA profiles appear instead of L elements. what could be the problem? In addition, the C10 column in the data gives an error when the analysis is made due to the B32 inclined beam connected to this column. However, there is no error in the C09 column next to it. However, both beams are connected at the same angle. Column height has nothing to do with it, I tried it and it gives the same error.
