Re: The program runs very slowly, every change takes 30 seconds Hello Mr. Erhan; You are experiencing slowdown in your project, especially in which situation and when trying to make changes. I did not encounter any slowness when I opened your project and performed various operations in a few joints, when I tried to edit tabs such as column settings, flooring, or when I made analysis and got all the steel drawings. Can you check if you have uploaded your project file correctly? If the slow version of your project is this saved file, can you restart your computer and open the program by pressing and holding ctrl+shift? If the slowness continues, let me know. ** The combination you use for the weak direction is not geometrically appropriate, it is the beam-beam weak direction combination. Column-beam stiffened butt plate connection, which you can see in the image, is geometrically appropriate. In this sense, edit your model. Good work.
