Re: HOW TO FIX USER ACCURATED ANALYSIS ERRORS yes I am new to idecad. I did not receive education. You're right, I mixed up the reinforcement part. It's about the reinforced concrete part. As you said here, the soil tension is checked. I think there are no other programs to teach in Ankara. I think there are other programs, but I like this program. I couldn't look at the 6 version of it. Of course, we have shortcomings, we ask you about them, thank you for helping. I learn as I ask questions, I hope I do not bore you. It is very enjoyable for me, believe me.. I hope I am not giving you a headache. '' if there is 17 t / m2 tension in the ground tension distribution of these 16 points, 1 of them can be 35 t / m2. You examine it in the soil stress distribution and take the initiative and say calculate according to the average soil stress. There are other ways to eliminate these splashes. You can calculate the superstructure and substructure together, or you can define your curtains as shell elements. Or you can define regional arcs in the raft. And you can even make changes in the superstructure.'' In short, when we make calculations, we can interpret that it is more than 17t/m2 in total, but a close value and that it does not exceed the maximum stress, and we can interpret according to the average stress? You can calculate the superstructure and substructure together, or you can define your curtains as shell elements. How do we examine the soil stress distribution? Can you open the threads? define regional arcs in a raft
