First of all, I have to state that I am a novice in using the program. I'm having problems with this project that I can't get out of and can't find a solution to, probably because of a burr-stinging inexperienced problem. First of all, the raft foundation is insufficient and I couldn't quite figure out where the source of the problem is. I don't know if it's due to a problem when planning the floors or my ignorance in IDEcad. I do not want to change the system, there is a shop at the bottom, but even if it can only be solved with a system change, I do not avoid applying it. I had a lot of geometry problems, I solved most of them, but there is a problem with the placement of columns that I could not find an easy solution. I look forward to your help in this matter. Other than that, there are no problems in the project, there is an anomaly in the S11 column, as if the program does not care about what I say, even if I change the thickness and length, it does not respond to me much in the analysis. I wonder if the double diagram is caused by the elevator shaft or something else, I would appreciate it if you could inform me about it. I haven't taken the point of blockage too far, I haven't entered the stair floors yet, I have to cut the elevator shaft from the raft, etc. There are a few tasks that I am aware of. I look forward to your suggestions and help. I am at a point where I am clogged with my own knowledge base. Good luck with.
